To Our Stockholders,
The last year has both highlighted the criticality of cybersecurity in every aspect of modern life and tested the foundational strength of our business. I am particularly proud of the way our employees have risen to the challenge of navigating this complex world where ransomware, breaches and nation-state threats regularly make the news. Tenable has been there, at every step along the way, to help our customers understand and reduce their cybersecurity risk, helping keep their businesses safer while accelerating their ability to innovate.
Our commitment to our customers
2021 was a year of milestones on many fronts, including a dramatic rise in high-profile cyber problems. As bad actors evolve from retrieving personal identification to crippling businesses and our communities, we remain completely focused on enabling our customers to answer the one question that is most critical to any digital enterprise: “How Secure Am I?” Our customer base has embraced digital transformation and all that it entails – shifting to the cloud and hyper-distributed modern applications. These same customers increasingly recognize that every new technology investment, every computer and asset type is interconnected and introduces risk. Tenable is working hand-in-glove with more than 40,000 organizations to help them expand their vulnerability management (VM) discipline to other areas of their infrastructure so they can understand and reduce their exposure to risk across software, identity and configurations.
During the year we delivered a platform that can provide our customers with the leverage they need by securing their tech investments so they can accelerate innovation. Tenable.ep brings our point solutions together to deliver the holistic insights and analytics modern enterprises require. We’re helping them understand how areas of attack are interconnected with an integrated solution and a complete picture of cyber risks. We are delivering unified visibility into code, configurations, assets and workloads. Because cyber risk is business risk, Tenable.ep helps organizations understand security concerns in the broader context of their business priorities. Tenable.ep combines the best of our past and present, establishing a better together framework that will serve our customers now as well as over the long term.
Our commitment to corporate social responsibility
In April of 2021, we published our first corporate sustainability report. We outlined our commitment to the environment, to our people and the investments we've made to foster this goal.
We know that Tenable is stronger because we bring different and inclusive perspectives to the table. What’s more, we are 100% focused on making Tenable a premier employer -- a company where people can thrive and succeed with meaningful careers. To that end, we instituted a number of initiatives to enhance the employee experience, including:
Two days annually for career development,
Enhanced learning opportunities, including diversity, equity and inclusion training,
Remote work flexibility,
Offices closed every Friday in August, and
Annual equity grants to all eligible employees in good standing.
Nothing has made me more proud than watching the heroic efforts of our team throughout the last year. Their dedication to our customers, to our partners and to each other are constant. We will

continue to invest in our employees just as surely as we will continue to achieve great results together.
Our commitment to financial performance
Going into 2021 we had great confidence in our ability to execute on our key initiatives even with the great macro uncertainty created by the global pandemic. We are incredibly proud of our results and the financial performance that reflects the team’s hard work. A few highlights:
Accelerated growth in each of the four quarters,
Achieved Rule of 40 (defined below) for full-year 2021, and
Added a record 1,800+ enterprise platform customers, and 250+ net new 6-figure customers.
Our commitment to our investors
In December we held our first investor day. We recognize the importance that investors play in our success and appreciate their diverse views. We pride ourselves on our investor relationships and will continue to seek out thoughtful ways to deepen our dialog.
And we’re just getting started. Just as we pioneered the vulnerability management market, we are once again at the forefront of innovation where technology investments, devices, risks and opportunities are profoundly interconnected. We’re helping organizations of all sizes rethink how they assess and mitigate risk. We believe foundational cyber can and should accelerate innovation in a cloud-first world. And we believe every organization must be able to answer the question, “How secure are we?”
Sincerely,
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-amitsiga.jpg

Business Overview - 2021 Highlights
We are a leading provider of Cyber Exposure solutions. Cyber Exposure is a discipline for managing, measuring and comparing cybersecurity risk in the digital era.
We have continued to expand and diversify our platform offerings from traditional vulnerability management (VM) solutions, which include Tenable.sc and Nessus, to our cloud exposure solutions, which include Tenable.ep, Tenable.io, Tenable.cs, Tenable Web Scanning, or Tenable.io WAS, Tenable.ad and Tenable.ot. Our platform offerings provide broad visibility into security issues such as vulnerabilities, misconfigurations, internal and regulatory compliance violations and other indicators of the state of an organization’s security across IT infrastructure and applications, cloud environments, DevOps environments, Active Directory and Identity environments, and Industrial IoT and OT environments. We also provide deep analytics to help organizations score, trend and compare their cyber exposure over time, and communicate cyber risk in business terms to make better strategic decisions. Our platform offerings integrate and analyze data from our native collectors alongside IT asset, vulnerability and threat data from third-party systems and applications to prioritize security issues for remediation and focus an organization’s resources based on risk and business criticality.
Our 2021 highlights were as follows:
Launched Tenable.ep, our unified, risk-based vulnerability management exposure platform designed to provide visibility across Tenable’s solutions and prioritize vulnerabilities using predictive analytics.
Achieved FedRAMP authorization for Tenable.io and Tenable.io Web App Scanning, allowing the U.S. federal government to deploy both products across various departments and agencies.
Acquired Alsid SAS and Accurics, Inc. for $98.5 million and $160.0 million, respectively.
Closed our new credit facility comprised of a $375 million senior secured term loan and a $50 million senior secured revolving credit facility.
Revenue was $541.1 million, a 23% increase year-over-year.
Calculated current billings was $617.2 million, a 25% increase year-over-year.
GAAP loss from operations was $41.8 million, compared to a loss of $36.4 million in 2020; Non-GAAP income from operations was $51.0 million, compared to $25.8 million in 2020.
GAAP net loss per share was $0.44, compared to a loss per share of $0.42 in 2020; Non-GAAP diluted earnings per share was $0.34, compared to $0.19 in 2020.
Unlevered free cash flow was $95.2 million, compared to $44.3 million in 2020.
Achieved Rule of 40 for full-year 2021, which we define as the sum of percentages for revenue growth and unlevered free cash flow margin.
Refer to the appendix for reconciliations of non-GAAP measures to comparable GAAP measures.

FOR THE 2022 ANNUAL MEETING OF STOCKHOLDERS
May 25, 2022
QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING
Why did I receive a notice regarding the availability of proxy materials on the Internet?
Pursuant to rules adopted by the Securities and Exchange Commission (the “SEC”), we have elected to provide access to our proxy materials over the Internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the “Notice”) because the Board of Directors (the "Board of Directors" or the "Board") of Tenable Holdings, Inc. (sometimes referred to as the “Company” or “Tenable”) is soliciting your proxy to vote at the 2022 Annual Meeting of Stockholders, including at any adjournments or postponements of the meeting. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request a printed copy may be found in the Notice.
We intend to mail the Notice on or about April 13, 2022 to all stockholders of record entitled to vote at the Annual Meeting.
Will I receive any other proxy materials by mail?
We may, in our discretion, elect to send you a proxy card. We may also send you a second Notice on or after April 25, 2022.
How do I attend the Annual Meeting?
The Annual Meeting will be a virtual stockholder meeting through which you can listen to the meeting and vote online. The Annual Meeting can be accessed by visiting https://www.proxydocs.com/TENB and entering your control number which is included in the proxy materials mailed to you. Upon completing your registration, you will receive further instructions via email, including a unique link that will allow you access to the Annual Meeting.

Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on March 31, 2022 will be entitled to vote at the Annual Meeting. On this record date, there were 110,286,675 shares of common stock outstanding and entitled to vote.
Stockholder of Record: Shares Registered in Your Name
If on March 31, 2022 your shares were registered directly in your name with Tenable’s transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote online during the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time or vote by proxy over the telephone or Internet as instructed below to ensure your vote is counted.
Beneficial Owner: Shares Registered in the Name of a Broker or Bank
If on March 31, 2022 your shares were held, not in your name, but rather in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You will receive instructions from your broker, bank or agent that you must follow in order to submit your voting instructions and have your shares voted at the Annual Meeting. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares online during the Annual Meeting unless you request and obtain a valid proxy from your broker, bank or other agent.
What am I voting on?
There are three matters scheduled for a vote:
Election of three directors (Proposal 1);
Ratification of selection by the Audit Committee of the Board of Directors of Ernst & Young LLP as independent registered public accounting firm of the Company for the year ending December 31, 2022 (Proposal 2); and
Advisory approval, on a non-binding basis, of the compensation of our Named Executive Officers as disclosed in this proxy statement (Proposal 3).
What if another matter is properly brought before the meeting?
The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.
How do I vote?
You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For Proposals 2 and 3, you may vote “For” or “Against” or "Abstain" from voting.

Stockholder of Record: Shares Registered in Your Name
If you are a stockholder of record, you may vote online during the Annual Meeting, vote by proxy using a proxy card that you may request or that we may elect to deliver at a later time, vote by proxy over the telephone or vote by proxy through the Internet. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote online during the meeting even if you have already voted by proxy.
To vote online during the meeting, access the Annual Meeting by visiting www.proxypush.com/TENB and entering your control number which is included in the proxy materials mailed to you. Please have your Notice in hand when you access the website and follow the instructions.
To vote using the proxy card, simply complete, sign and date the proxy card that may be delivered and return it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.
To vote over the telephone, dial toll-free 866-230-6244 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the Notice. To ensure your vote is counted, your telephone vote must be received either prior to the start of the meeting or, if you are attending the meeting, before the polls close during the meeting.
To vote through the Internet, go to www.proxypush.com/TENB to complete an electronic proxy card. You will be asked to provide the control number from the Notice. To ensure your vote is counted, your Internet vote must be received either prior to the start of the meeting or, if you are attending the meeting, before the polls close during the meeting.
Beneficial Owner: Shares Registered in the Name of Broker or Bank
If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received a Notice containing voting instructions from that organization rather than from Tenable. Simply follow the voting instructions in the Notice to ensure that your vote is counted. To vote online during the Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization to request a proxy form.
Internet proxy voting will be provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.
How many votes do I have?
On each matter to be voted upon, you have one vote for each share of common stock you own as of March 31, 2022.
If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?
If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or online during the Annual Meeting, your shares will not be voted.
If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all nominees for director, “For” the ratification of Ernst & Young LLP as independent auditors for the year ending December 31, 2022,

and "For" the approval of, on a non-binding advisory basis, the compensation of our Named Executive Officers. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his best judgment.
If I am a beneficial owner of shares held in street name and I do not provide my broker or bank with voting instructions, what happens?
If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. In this regard, brokers, banks and other securities intermediaries may use their discretion to vote your “uninstructed” shares with respect to matters considered to be “routine” under applicable rules, but not with respect to “non-routine” matters. Proposals 1 and 3 are considered to be “non-routine” under applicable rules, meaning that your broker may not vote your shares on those proposals in the absence of your voting instructions. However, Proposal 2 is considered to be “routine” under applicable rules, meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 2.
If you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.
Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.
What does it mean if I receive more than one Notice?
If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notice to ensure that all of your shares are voted.
Can I change my vote after submitting my proxy?
Stockholder of Record: Shares Registered in Your Name
Yes. You can revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:
You may submit another properly completed proxy card with a later date.
You may grant a subsequent proxy by telephone or through the Internet.
You may send a timely written notice that you are revoking your proxy to Tenable Holdings, Inc., Attention: Corporate Secretary at 6100 Merriweather Drive, 12th Floor, Columbia, Maryland 21044.
You may attend the Annual Meeting and vote online. Simply attending the meeting will not, by itself, revoke your proxy.

Your most current proxy card or telephone or Internet proxy is the one that is counted.
Beneficial Owner: Shares Registered in the Name of Broker or Bank
If your shares are held by your broker, bank or other agent, you should follow the instructions provided by your broker, bank or other agent.
When are stockholder proposals and director nominations due for next year’s Annual Meeting?
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 14, 2022, to 6100 Merriweather Drive, 12th Floor, Columbia, Maryland 21044. If you wish to nominate an individual for election at, or bring business other than through a stockholder proposal before, the 2023 Annual Meeting of Stockholders, you must deliver your notice to our Corporate Secretary at the address above between January 25, 2023 and February 24, 2023. Your notice to the Corporate Secretary must set forth information specified in our bylaws, including your name and address and the class and number of shares of our stock that you beneficially own. In addition to satisfying the foregoing requirements under Tenable's bylaws, to comply with the universal proxy rules (once effective), stockholders who intend to solicit proxies in support of director nominees other than Tenable's nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), no later than March 26, 2023.
If you propose to bring business before an annual meeting of stockholders other than a director nomination, your notice must also include, as to each matter proposed, the following: (1) a brief description of the business desired to be brought before such annual meeting and the reasons for conducting that business at the annual meeting and (2) any material interest you have in that business. If you propose to nominate an individual for election as a director, your notice must also include, as to each person you propose to nominate for election as a director, the following: (1) the name, age, business address and residence address of the person, (2) the principal occupation or employment of the person, (3) the class and number of shares of our stock that are owned of record and beneficially owned by the person, (4) the date or dates on which the shares were acquired and the investment intent of the acquisition; (5) a statement whether such person, if elected, intends to tender, promptly following such person’s failure to receive the required vote for election or re-election at the next meeting at which such person would face election or re-election, an irrevocable resignation effective upon acceptance of such resignation by the Board of Directors and (6) any other information concerning the person as would be required to be disclosed in a proxy statement soliciting proxies for the election of that person as a director in an election contest (even if an election contest is not involved), or that is otherwise required to be disclosed pursuant to Section 14 of the Exchange Act, and the rules and regulations promulgated under the Exchange Act, including the person's written consent to being named as a nominee and to serving as a director if elected. We may require any proposed nominee to furnish other information as we may reasonably require to determine the eligibility of the proposed nominee to serve as an independent director or that could be material to a reasonable stockholder's understanding of the independence, or lack of independence, of the proposed nominee.
For more information, and for more detailed requirements, please refer to our Amended and Restated Bylaws, filed as Exhibit 3.4 to our Registration Statement on Form S-1 (File No. 333-226002), filed with the SEC on June 29, 2018.

Table of Contents

How are votes counted?
Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for Proposal 1, the proposal to elect directors, votes “For,” “Withhold” and broker non-votes (described below); for Proposal 2, the proposal to ratify our independent auditors, votes “For,” “Against” and “Abstain”; and, for Proposal 3, the proposal to approve, on a non-binding advisory basis, the compensation of our Named Executive Officers, ”For," "Against" and “Abstain” and broker non-votes. If you “Abstain” it will be counted towards the vote total for Proposals 2 and 3. For Proposal 2 and 3, it will have the same effect as “Against” votes. Broker non-votes on Proposals 1 and 3 will have no effect and will not be counted towards the vote total for those proposals. We do not expect broker non-votes on Proposal 2.
What are “broker non-votes”?
As discussed above, when a beneficial owner of shares held in street name does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine” under applicable rules, the broker, bank or other such agent cannot vote the shares. These un-voted shares are counted as “broker non-votes.” Proposal 1 and 3 are considered to be “non-routine” under applicable rules and we therefore expect broker non-votes on these proposals. However, as Proposal 2 is considered “routine” under applicable rules, we do not expect broker non-votes on this proposal.
As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you must provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.
How many votes are needed to approve each proposal?
For Proposal 1, the election of directors, the three nominees receiving the most “For” votes from the holders of shares present online at the meeting or represented by proxy and entitled to vote on the election of directors will be elected. Only votes “For” will affect the outcome. Broker non-votes will have no effect.
To be approved, Proposal 2, ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for 2022, must receive “For” votes from the holders of a majority of shares present online at the meeting or represented by proxy and entitled to vote on the matter. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Since brokers have authority to vote on your behalf with respect to Proposal 2, we do not expect broker non-votes on this proposal.
For Proposal 3, advisory approval of the compensation of our Named Executive Officers will be considered to be approved if it receives "For" votes from the holders of a majority of the shares present online at the meeting or represented by proxy and entitled to vote thereon to be approved. If you “Abstain” from voting, it will have the same effect as an “Against” vote on this proposal. Broker non-votes will have no effect.
What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present online at the meeting or represented by proxy. On the record date, there were 110,286,675 shares outstanding
13

Table of Contents

and entitled to vote. Thus, the holders of 55,143,338 shares must be present online at the meeting or represented by proxy at the meeting to have a quorum.
Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote online during the virtual meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairperson of the meeting or the holders of a majority of shares present online at the meeting or represented by proxy may adjourn the meeting to another date.
Will a list of record stockholders as of the record date be available?
Upon request, a list of our record shareholders as of the close of business on the record date will be made available to stockholders. In addition, for the ten days prior to the Annual Meeting, the list will be available upon request for examination by any stockholder of record for a legally valid purpose. To access the list of record shareholders beginning May 15, 2022 and until the Annual Meeting, stockholders should email David Bartholomew, Associate General Counsel, at dbartholomew@tenable.com.
How do I ask a question at the Annual Meeting?
Only stockholders of record as of March 31, 2022 may submit questions or comments in advance of the virtual stockholders meeting. If you would like to submit a question or comment, you may do so prior to 5:00 p.m. Eastern Time on May 21, 2022 by following the instructions in your registration documents on https://www.proxydocs.com/TENB.
To help ensure that we have a productive and efficient meeting, and in fairness to all stockholders in attendance, you will also find posted our rules of conduct for the Annual Meeting when you log in prior to the start of the Annual Meeting. In accordance with the rules of conduct, we ask that you limit your submission to one brief question or comment that is relevant to the Annual Meeting or our business and that such remarks are respectful of your fellow stockholders and meeting participants. Our management may group submitted questions by topic with a representative question read aloud and answered. In addition, questions may be ruled out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the speaker's own personal, political or business interests. Questions will be addressed in the "Question and Answer" portion of the Annual Meeting.
What do I do if I have technical difficulties in connection with the Annual Meeting?
If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Annual Meeting login page. Technical support will be available beginning at approximately 12:00 p.m. Eastern time on May 25, 2022.
How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

PROPOSAL 1
ELECTION OF DIRECTORS
Tenable’s Board of Directors is divided into three classes and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.
The Board of Directors currently consists of nine members. There are three directors in the class whose term of office expires in 2022. Mr. Yoran was previously elected by Tenable's stockholders. Mses. Higgins and Howe were recommended to the Board by a member of senior management and the chief executive officer, respectively. If elected at the Annual Meeting, each of these nominees would serve until the 2025 Annual Meeting of Stockholders and until their successor has been duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is the Company’s policy to invite and encourage directors and nominees for director to attend each annual meeting of stockholders. In 2021, eight of our then serving directors attended the Annual Meeting.
Directors are elected by a plurality of the votes of the holders of shares present online at the meeting or represented by proxy and entitled to vote on the election of directors. Accordingly, the three nominees receiving the highest number of affirmative votes will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the three nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead will be voted for the election of a substitute nominee proposed by the Board. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that any nominee will be unable to serve.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE
Independence of the Board of Directors
As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by the Board of Directors. The Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent registered public accounting firm, the Board has affirmatively determined that the following seven of our current directors are independent directors within the meaning of the applicable Nasdaq listing standards: Arthur W. Coviello, Jr., Kimberly L. Hammonds, Jerry M. Kennelly, Niloofar Razi Howe, A. Brooke Seawell, Raymond Vicks, Jr., and Linda Zecher Higgins. The Board determined that Messrs. Li and Wells, who resigned from the Board of Directors in May 2021 and January 2022 respectively, were also independent while each served on the Board. In making this determination, the Board found that none of these directors or nominees for director had a material or other disqualifying relationship with the Company.
Board Leadership Structure
Our Board of Directors is currently chaired by Mr. Yoran, our Chief Executive Officer. The Board believes that combining the positions of Chief Executive Officer and Board Chair helps to ensure that the Board and management act with a common purpose and provides a single, clear chain of command to execute Tenable’s strategic initiatives and business plans. In addition, the Board believes that a combined Chief Executive Officer/Board Chair is better positioned to act as a bridge between management and the Board, facilitating the regular flow of information. The Board also believes that it is advantageous to have a Board Chair with significant history with and extensive knowledge of Tenable (as is the case with Mr. Yoran).
The Board has also appointed Mr. Coviello as lead independent director in order to help reinforce the independence of the Board as a whole. The position of lead independent director has been structured to serve as an effective balance to Mr. Yoran’s leadership as our combined Chief Executive Officer and Board Chair. The lead independent director is empowered to, among other duties and responsibilities, work with the Chief Executive Officer and Board Chair to develop and approve an appropriate Board meeting schedule and Board meeting agendas; provide the Chief Executive Officer and Board Chair feedback on the quality, quantity, and timeliness of the information provided to the Board; develop the agenda and moderate executive sessions of the independent members of the Board; preside over Board meetings when the Chief Executive Officer and Board Chair is not present or when Board or Chief Executive Officer performance or compensation is discussed; act as principal liaison between the independent members of the Board and Chief Executive Officer and Board Chair; convene meetings of the independent directors as appropriate; and perform such other duties as may be established or delegated by the Board. As a result, the Company believes that the lead independent director can help ensure the effective independent functioning of the Board in its oversight responsibilities.

Role of the Board in Risk Oversight
One of the Board’s key functions is informed oversight of Tenable’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. In particular, our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for the Company.
Our Audit Committee has the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee also monitors compliance with legal and regulatory requirements, in addition to oversight of the performance of our internal audit function. Audit Committee responsibilities also include oversight of information security risk management, including thorough oversight of the Cybersecurity Subcommittee of the Audit Committee, which assists the Audit Committee and the Board in overseeing cybersecurity risk management.
Our Nominating and Corporate Governance Committee monitors the effectiveness of our corporate governance guidelines, including whether they are successful in preventing illegal or improper liability-creating conduct.
Our Compensation Committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.
Typically, the entire Board meets with members of management responsible for risk management at least annually, and the applicable Board committees meet at least annually with the employees responsible for risk management in the committees’ respective areas of oversight. Both the Board as a whole and the various standing committees receive periodic reports from members of management responsible for risk management, as well as incidental reports as matters may arise. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board as quickly as possible.
Meetings of the Board of Directors
The Board of Directors met six times during 2021. Each director attended 75% or more of the aggregate number of meetings of the Board and of each of the committees on which he or she served during the portion of the last year for which he or she was a director or committee member.

Below is a description of each committee of the Board of Directors. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board of Directors has determined that each member of each committee meets the applicable Nasdaq rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company.
Audit Committee
The Audit Committee of the Board of Directors was established by the Board in accordance with Section 3(a)(58)(A) of the Exchange Act to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions. The principal duties and responsibilities of our audit committee include, among other things:
selecting a qualified firm to serve as the independent registered public accounting firm to audit our financial statements;
helping to ensure the independence and performance of the independent registered public accounting firm;
discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent registered public accounting firm, our interim and year-end operating results, including a review of our disclosures under "Management's Discussion and Analysis of Financial Condition and results of Operations";
developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters;
reviewing our policies on risk assessment and risk management;
overseeing the organization and performance of the Company's internal audit function;

meeting in executive session with management and the Company's independent registered public accountants;
reviewing related party transactions;
obtaining and reviewing a report by the independent registered public accounting firm at least annually, that describes its internal quality-control procedures, any material issues with such procedures, and any steps taken to deal with such issues when required by applicable law; and
approving (or, as permitted, pre-approving) all audit and all permissible non-audit services to be performed by the independent registered public accounting firm.
The Audit Committee is currently composed of three directors: A. Brooke Seawell, Kimberly L. Hammonds, and Raymond Vicks, Jr. Arthur Coviello served as a member of the Audit Committee until January 2022. The Audit Committee met eight times during 2021. The Board has adopted a written Audit Committee charter that is available to stockholders on our website at www.tenable.com.
The Board of Directors reviews the Nasdaq listing standards definition of independence for Audit Committee members on an annual basis and has determined that all members of the Company’s Audit Committee are independent (as independence is currently defined in Rule 5605(c)(2)(A)(i) and (ii) of the Nasdaq listing rules).
The Board of Directors has also determined that Messrs. Vicks and Seawell each qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of Messrs. Vicks and Seawell's level of knowledge and experience based on a number of factors, including their formal education, Mr. Seawell's experience as a chief financial officer of public reporting companies and Mr. Vicks' public accounting experience.
Report of the Audit Committee of the Board of Directors*
The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2021 with management of the Company. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and SEC. The Audit Committee has also received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm's communications with the audit committee concerning independence, and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee has recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Compensation Committee
The Compensation Committee of the Board of Directors acts on behalf of the Board to review, modify and oversee the Company’s compensation strategy, policies, plans and programs, including:
establishment of corporate and individual performance objectives relevant to the compensation of our executive officers, directors and other senior management and evaluation of performance in light of these stated objectives;
review and recommend to the Board for approval of the compensation and other terms of employment or service, including severance and change-in-control arrangements, of our Chief Executive Officer, the other executive officers and directors; and
administration of our equity compensation plans, bonus plans, benefit plans and other similar plans and programs.
The Compensation Committee is currently composed of three directors: Jerry M. Kennelly, Linda Zecher Higgins, and Niloofar Razi Howe. All members of the Company’s Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq listing rules. The Compensation Committee met five times during 2021. The Board has adopted a written Compensation Committee charter that is available to stockholders on our website at www.tenable.com.
Compensation Committee Processes and Procedures
Typically, the Compensation Committee meets quarterly and with greater frequency when necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer, Chief People Officer and Compensia, Inc. ("Compensia"), the compensation consultant engaged by the Compensation Committee. The Compensation Committee meets regularly in executive session. In addition to our Chief Executive Officer, our Chief People Officer and our General Counsel also regularly attend meetings at the invitation of the Compensation Committee and take part in discussions about executive compensation. From time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under its charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the compensation committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.
24

Table of Contents

During the past calendar year, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee retained Compensia as its compensation consultant. Our Compensation Committee identified Compensia based on Compensia's general reputation in the industry. The Compensation Committee requested that Compensia:
evaluate the efficacy of the Company’s existing compensation strategy and practices in supporting and reinforcing the Company’s long-term strategic goals; and
assist in refining the Company’s compensation strategy and in developing and implementing an executive compensation program to execute that strategy.
As part of its engagement, Compensia was requested by the Compensation Committee to review and update the group of companies that we use for comparative purposes and to perform an analysis of competitive performance and compensation levels for that group. The specific determinations of the Compensation Committee with respect to executive compensation for the year ended December 31, 2021, as well as the role of the compensation consultant in assisting with those determinations, are described in greater detail in the “Compensation Discussion and Analysis” section of this proxy statement.
Under its charter, the Compensation Committee may form, and delegate authority to, subcommittees as appropriate. In 2021, the Compensation Committee delegated authority to Mr. Yoran, in his capacity as our Chief Executive Officer and Chairman, to grant, without any further action required by the Compensation Committee, stock awards to certain employees who are not officers of the Company, up to and including employees at the senior vice president level. The purpose of this delegation of authority is to enhance the flexibility of equity award administration within the Company and to facilitate the timely grant of stock awards to non-management employees, particularly new employees and promoted employees, within specified limits approved by the Compensation Committee. The number of shares underlying awards approved by Mr. Yoran are subject to maximum limits based on a targeted market range of share value and other parameters for each recipient’s classification as set forth in guidelines approved by the Compensation Committee from time to time. Typically, as part of its oversight function, the Compensation Committee reviews on a quarterly basis the list of grants made by Mr. Yoran. During 2021, Mr. Yoran exercised his authority to grant a total of 566,582 restricted stock units ("RSUs") to qualifying employees. No other equity awards were granted pursuant to Mr. Yoran’s authority during 2021.
The Compensation Committee typically makes adjustments to annual compensation, approves changes to the key financial metric targets and formulas used to determine annual bonus payments, approves additional equity awards and establishes new performance objectives at one or more meetings held during the first quarter of the year. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data,

analyses of historical executive compensation levels and current company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant.
Compensation Committee Interlocks and Insider Participation
None of the current members of our Compensation Committee has ever been an executive officer or employee of ours. None of our executive officers currently serve, or has served during the last completed year, on the compensation committee or board of directors of any other entity that has one or more executive officers serving as a member of our Board of Directors or Compensation Committee.
Report of the Compensation Committee of the Board of Directors*
The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis (“CD&A”) contained in this proxy statement. Based on this review and discussion, the Compensation Committee has recommended to the Board of Directors that the CD&A be included in this proxy statement and incorporated into the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Nominating and Corporate Governance Committee
The Nominating and Corporate Governance Committee of the Board of Directors is responsible for identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board), reviewing and evaluating incumbent directors, recommending to the Board for selection candidates for election to the Board of Directors, making recommendations to the Board regarding the membership of the committees of the Board, assessing the performance of management and the Board, and developing a set of corporate governance principles for the Company.
The Nominating and Corporate Governance Committee is currently composed of three directors: Arthur W. Coviello, Jr., Kimberly L. Hammonds, and Linda Zecher Higgins. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing rules). The Nominating and Corporate Governance Committee met four times during 2021. The Board has adopted a written Nominating and Corporate Governance Committee charter that is available to stockholders on the our website at www.tenable.com.
The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including the ability to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Corporate Governance Committee also intends to consider such factors as
26

Table of Contents

possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of the Company, demonstrated excellence in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of the Company’s stockholders. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. Board diversity and inclusion is critical to Tenable’s success. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of the Company and the long-term interests of stockholders. In conducting this assessment, the Nominating and Corporate Governance Committee typically considers diversity (including gender, racial and ethnic diversity), age, skills and such other factors as it deems appropriate, given the current needs of the Board and the Company, to maintain a balance of knowledge, experience and capability.
The Nominating and Corporate Governance Committee appreciates the value of thoughtful Board refreshment, and regularly identifies and considers qualities, skills and other director attributes that would enhance the composition of the Board. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Corporate Governance Committee will review these directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors’ independence. The Committee also takes into account the results of the Board’s self-evaluation, conducted annually on a group and individual basis. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but also engages professional search firms from time to time to assist in identifying potential candidates. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board by majority vote.
The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee at the following address: Tenable Holdings, Inc., Attention: Corporate Secretary, 6100 Merriweather Drive, 12th Floor, Columbia, Maryland 21044, at least 90 days, but not more than 120 days prior to the anniversary date of the preceding year's annual meeting of stockholders. Submissions must include the name and address of the stockholder on whose behalf the submission is made, the number of shares of Tenable stock owned beneficially by such stockholder on the date of the submission, the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information and a description of the proposed nominee's qualifications as a director. Any submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

PROPOSAL 2
RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Audit Committee of the Board of Directors has selected Ernst & Young LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2022 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Ernst & Young LLP has audited the Company’s financial statements since 2014. Representatives of Ernst & Young LLP are expected to be present online at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
Neither the Company’s Bylaws nor other governing documents or law require stockholder ratification of the selection of Ernst & Young LLP as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of Ernst & Young LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.
The affirmative vote of the holders of a majority of the shares present online at the meeting or represented by proxy and entitled to vote on the matter at the Annual Meeting will be required to ratify the selection of Ernst & Young LLP.

Pre-Approval Policies and Procedures
The Audit Committee has adopted a policy and procedures for the pre-approval of audit and non-audit services rendered by the Company’s independent registered public accounting firm, Ernst & Young LLP. The policy generally pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent registered public accounting firm or on an individual, explicit, case-by-case basis before the independent registered public accounting firm is engaged to provide each service. The Chair of the Audit Committee has been delegated authority to pre-approve certain audit and non-audit services, but the decision must be reported to the full Audit Committee at its next scheduled meeting.
The Audit Committee has determined that the rendering of pre-approved services other than audit services by Ernst & Young LLP is compatible with maintaining the principal accountant’s independence.
THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 2.

PROPOSAL 3
ADVISORY VOTE TO APPROVE THE NAMED EXECUTIVE OFFICER COMPENSATION
The Dodd-Frank Wall Street Reform and Consumer Protection Act and Section 14A of the Exchange Act enable our stockholders to approve, on an advisory non-binding basis, the compensation of our Named Executive Officers as disclosed in this proxy statement. This proposal, commonly known as a "Say-on-Pay" proposal, gives our stockholders the opportunity to express their views on our Named Executive Officers' compensation as a whole. The vote is not intended to address any specific item of compensation or any specific Named Executive Officer, but rather the overall compensation of all our Named Executive Officers and the philosophy, policies and practices described in this proxy statement. At the 2020 Annual Meeting of Stockholders, the stockholders indicated their preference that the Company solicit a Say-on-Pay vote every year. The Board has adopted a policy that is consistent with that preference. In accordance with that policy, this year, we are asking stockholders to approve, on an advisory basis, the compensation of our Named Executive Officers as disclosed in this proxy statement in accordance with SEC rules.
The Say-on-Pay vote is advisory, and therefore is not binding on us, the Compensation Committee or the Board. The Say-on-Pay vote will, however, provide information to us regarding investor sentiment about our executive compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining executive compensation for the remainder of the current year and beyond. The Board and our Compensation Committee value the opinions of our stockholders and to the extent there is any significant vote against the Named Executive Officer compensation as disclosed in this proxy statement, we will endeavor to communicate with stockholders to better understand the concerns that influenced the vote, consider our stockholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.
The compensation of our Named Executive Officers subject to the vote is disclosed in the Compensation Discussion and Analysis section, the compensation tables and the related narrative disclosure contained in this proxy statement. As discussed in those disclosures, we believe that our compensation policies and decisions are aligned with our stockholders’ interests to support long-term value creation and enable us to attract and retain talented executives.
Accordingly, the Board is asking the stockholders to indicate their support for the compensation of our Named Executive Officers as described in this proxy statement by casting a non-binding advisory vote “FOR” the following resolution:
“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion is hereby APPROVED.”
Advisory approval of this proposal requires the vote of the holders of a majority of the shares present online or represented by proxy and entitled to vote on the matter at the annual meeting. Unless the Board decides to modify its policy regarding the frequency of soliciting Say-on-Pay votes, the next scheduled Say-on-Pay vote will be at the 2023 Annual Meeting.
THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 3.

CORPORATE SOCIAL RESPONSIBILITY
We believe good governance at all levels is necessary to drive corporate responsibility, which in turn promotes the long-term interests of our stockholders and strengthens Board and management accountability. We focus our efforts in the following key areas:
Governance of sustainability;
Environmental stewardship; and
Social responsibility in: cybersecurity, diversity and inclusion, employee engagement, and community involvement.
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-legal-dark2xx100a.jpg
Governance of Sustainability
As a part of its primary duty overseeing the Company's corporate strategy, our Board also oversees how environmental and social issues may impact the long-term interests of our stockholders and stakeholders. We stress that corporate responsibility is part of every employee’s job because achieving operational excellence is intrinsically tied to how responsibly we run our business.
As a part of this endeavor, the Board oversees the management team as it seeks to meet the Company's goals and responsibilities relating to sustainability and corporate social responsibility, particularly those that may affect the stakeholders and stockholders of our company, and the communities in which we operate. In addition to our governance best practices, we consider environmental and social issues in our operations. As part of overseeing our corporate strategy and our enterprise risk management program, our Board has a degree of insight into our environmental and social practices. We believe that socially responsible operating practices go hand in hand with generating value for our stockholders, providing cybersecurity solutions for our clients, being good neighbors within our communities, and being a good employer to our employees. In our view, our corporate governance is more effective when we consider environmental and social issues as part of our oversight of corporate strategy, key risks, and our operations more generally.
In 2020, we pooled internal and external resources to assess environmental, social and governance ("ESG") factors that are material to our business. With the assistance of external ESG consultants, we analyzed our businesses to better understand our material ESG risks and opportunities relevant for our company based on the views held by our stockholders, leading ESG frameworks and ESG rating agencies. We utilized criteria established by the Sustainability Accounting Standard Board and the Task Force on Climate-related Disclosures to perform the assessment. In April 2021, we published our first corporate sustainability report and our efforts in this regard are ongoing.
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-earth-dark2xx100a.jpg
Environmental Stewardship
Our Board and management team recognize that we have a role to play in environmental stewardship. Given that the Company is a software solutions company, greenhouse gas emissions and water and energy usage are not material factors to the day-to-day operations of our business. We believe, however, that environmentally responsible operating practices are important to generating value for our stockholders, being a good partner with our customers, and being a good employer to our employees.

Energy consumption and usage within data centers is an important component of our day-to-day operations of our business. We outsource our data center needs to Amazon Web Services (“AWS”). In 2014, AWS shared its long-term commitment to achieve 100 percent renewable energy usage for the global AWS infrastructure footprint. Our new corporate headquarters is a LEED Certified Gold for Core Construction.
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-lock-dark2xx100a.jpg
Cybersecurity
The Company takes great pride in assisting our customers with enhancing their security posture through the use of our services and products. We understand that customers must trust and have confidence in the security of an organization to use its service offerings for managing their vulnerability data. As such, we take the overall security of the Company's products and their supporting infrastructure very seriously.
The Company aligns its information security and risk management program to the NIST Cyber Security Framework and has implemented an information security management system (“ISMS”) to protect the confidentiality, integrity, and availability of assets against threats and vulnerabilities. The Company achieved ISO/IEC 27001:2013 certification, recognizing its proven commitment to the highest level of information security management.
Outside of internal improvements to our platform and customer relationship management, we do not use customer data for any other purposes.
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-leaders-dark2xx100a.jpg
Diversity and Inclusion
We seek to cultivate a diverse and inclusive workforce and environment to achieve exceptional business results. When we value and celebrate differences, we drive more innovation and grow closer to our customers, partners, and communities. We strive to be a career destination where employees from all backgrounds are welcome and empowered, treated with fairness and respect, presented with opportunities to make a difference, and provided opportunities to grow.
We undertake numerous efforts to increase diversity in our employee population and to foster a culture of fairness and belonging through a number of measures in our recruiting, engagement, retention, and outreach practices. Our dedicated Diversity & Inclusion Council and Employee Resource Groups – along with our committed leaders and managers – strive to attract and hire employees who bring broad diversity of background, thought, and style into the company and foster a sense of inclusion to make them want to stay. To support these initiatives, we build partnerships within our communities to support organizations and events that strive for greater representation of women and underrepresented minorities in cybersecurity, hold inclusion and bias mitigation training and offer targeted development opportunities to assist with career advancement. In addition, our global talent acquisition team received a diversity sourcing and recruiting certification.
We, in conjunction with a third party, evaluated our current pay scales, systems and infrastructure to identify any root causes that impact pay equity. From there, we designed a pay equity action plan and, in 2021, we executed on our plan and implemented systemic changes that resulted in a program to drive true and enduring pay equity. We recognize that pay equity requires ongoing analysis and are committed to regularly evaluating our practices for any inconsistencies.

Employee Engagement
The Company promotes and supports employee development and organizational effectiveness by providing high-quality learning and development programs. These programs are designed to meet individual, team, and organizational needs and objectives. We strive to enhance learning and development programs to create a better workplace environment and to build a better Tenable. We aim to incentivize our employees by aligning a portion of their compensation with the overall success of our business. All new hires are given an equity grant and there is broad employee participation in our Employee Stock Purchase Plan.
Our employee engagement program helps us understand employee sentiment on a wide range of topics throughout the employee lifecycle, providing insights that inform our decisions about company initiatives, employee programs, talent risks, management opportunities and more. In 2021, 83.2% of our eligible employees participated in our annual employee engagement survey.
https://cdn.kscope.io/f567462e76d662a63166bc14bd71cf31-heart-dark2xx100a.jpg
Community Involvement
We're a company built on our “We Care” core value, and we look to make a positive difference in everything that we do – in our work, with our customers and our colleagues, and in our communities.
We contribute to cybersecurity awareness, education, and scholarships, and inspire students to pursue cybersecurity careers or a STEM field of study.
Our We Care In Action (“WCIA”) campaign invites employees to submit nominations for charitable organization sponsorship. For each WCIA global cause selected annually by our employees, Tenable makes a donation, and we encourage our employees to contribute either by making a donation, volunteering their time in support of the cause, or learning about and helping to spread awareness for the cause. In 2020, we selected Make-A-Wish foundation as our WCIA global cause.
Each employee is given one day of paid leave per year to participate in volunteer activities for a charitable organization of their choice, including activities for a nonprofit or charitable organization, school events, disaster relief assistance, and peaceful activism.
Just as volunteering in our communities is an important aspect of our corporate culture, we encourage our employees to express their voices in local, state, and national public policy. Employees are given a total of one day off per year to exercise their right to vote.
In addition, we formed a federal Political Action Committee ("PAC") which allows eligible employees to pool their resources in order to support elected officials who share our interests on public policy matters that impact the future of our business. Tenable’s PAC is registered with the Federal Election Commission, and any contributions made by the PAC are fully funded by voluntary employee contributions, not corporate funds. Like other PACs, the Tenable PAC is a means by which our eligible employees can pool their personal contributions to help provide financial support for elected officials. It does not exist to advance any particular partisan or social agenda, but rather to ensure public policies promote growth for our business, our employees, and our customers.
Campaign contributions and similar expenditures are regulated by various federal, state and local laws. A campaign contribution is a donation of something of value to a candidate or a candidate’s committee, to a ballot measure committee, to a political party, or to a PAC that collects funds for the purpose of making contributions to candidates or other political committees. The laws regulating
34

Table of Contents

campaign contributions vary depending on the jurisdiction. The Company’s policy is that it does not make contributions to any candidates or their committees, political action committees or to party committees using Tenable resources.
This policy does not apply to or restrict the ability of our employees to participate voluntarily in political activities with their own funds and on their own time; however, we will not reimburse any employee for political contributions made from the employee’s personal funds. Our policy strictly prohibits coercion of our personnel to engage in political activities of any kind.

Base Salaries - We approved salary increases in 2021 for our Named Executive Officers in light of their and the company’s strong performance and to maintain market competitiveness relative to our peers. Raises ranged from 4.4% to 9.1%.
Cash Bonuses - Our cash bonus structure mirrored that of prior years and incorporated revenue, unlevered free cash flow and bookings goals. Our target cash bonuses are expressed as a percentage of base salary paid out based on quarterly and annual attainment, and remained comparable with 2020. Given our strong performance in these areas, cash bonuses were paid out in accordance with their plan formula above target at 109%.
Long-Term Incentive Compensation - We continue to provide a large percentage of our Named Executive Officers’ compensation opportunity through our long-term incentive compensation program. In 2021, our long-term incentive plan consisted of restricted stock unit (“RSU”) grants subject to service-based vesting. In order to remain competitive, the aggregate dollar value of Messrs. Yoran, Vintz and Riddick’s 2021 grants were increased relative to 2020 by 13.6%, 2.5% and 22.2% respectively.
We believe the increases in our Named Executive Officers' 2021 total direct compensation are consistent with our successful performance and company growth.
2021 Target Total Direct Compensation Overview
For 2021, 94% of our CEO’s total reported compensation and an average of 89% of our other Named Executive Officers’ total reported compensation was at-risk through quarterly and annual bonuses earned and equity incentives awarded, as reported in the Summary Compensation Table.

Listening to Our Stockholders
At our annual meeting of stockholders in 2021, we conducted our first advisory vote on executive compensation, or a say-on-pay vote. Approximately 90.4% of the votes cast on the say-on-pay proposal supported the proposal. In addition to our annual advisory vote on executive compensation, we are committed to ongoing engagement with our stockholders on executive compensation and corporate governance issues.

Table of Contents

Based on the support for last year’s say-on-pay proposal and our commitment to good governance, we did not adjust our compensation program for 2021, but have incorporated the following changes in our 2022 compensation programs:
Long-Term Incentive Plan – Incorporate performance restricted stock units (“PRSUs”) into our long-term incentive plan as a portion of our long-term incentive grants which will be earned based on objective and rigorous performance goals, and thereafter service-based vesting. We believe the introduction of performance criteria is appropriate to continue to align our executives’ pay with performance and incentivize the efficient execution on our growth strategy. For 2022, PRSUs make up 25% of the total grant date fair value of the long-term incentive grants for our Named Executive Officers.
Good Governance – We implemented pay governance practices including:
We have adopted stock ownership guidelines applicable to our non-employee directors.
We have in place a compensation recoupment policy under which compensation paid to or earned by our executives, including our Named Executive Officers, may be recovered in the event of financial restatements and misconduct that contributed to the financial restatements.
Executive Compensation Policies and Practices
We endeavor to maintain appropriate pay-for-performance alignment and sound governance standards as we review and manage executive compensation policies and practices. The Compensation Committee evaluates our executive compensation program on a regular basis to ensure that it is consistent with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. The following summarizes our key convictions with respect to executive compensation and related policies and practices:

Table of Contents

What We DoWhat We Do Not Do
Seek to tie pay to performance and stockholder value creation, while retaining top talent.
Maintain an independent Compensation Committee. Retain an independent compensation advisor.
Annual executive compensation strategy review. Multi-year vesting requirements for equity awards.
“Double-trigger” change-in-control arrangements.
Succession planning by full Board.
Executive retirement & perquisite benefits are limited to those offered to employees generally.
Annual Say-on-Pay voting.
Executive compensation “clawback” policy for our executives, including our Named Executive Officers, and stock ownership guidelines for our non-employee directors.
Stock incentive plans and executive employment agreements that provide for forfeiture of equity awards and severance if an executive is terminated for cause, including due to misconduct that results in reputational harm to the Company.
No guaranteed bonuses. No tax “gross ups” on payments on future post-employment compensation arrangements.
No hedging or pledging of our equity securities.
No mid-year adjustments or modifications of our cash or equity incentives in 2021 due to the COVID-19 pandemic and the recent volatile market condition.

Executive Compensation Philosophy and Objectives
Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance. To achieve these objectives, we believe that our executive compensation program should include short-term and long-term elements, including cash and equity compensation, and should reward consistent performance that meets or exceeds expectations. We evaluate both performance and compensation to make sure that the compensation provided to our executives remains competitive relative to compensation paid by companies of similar size operating in our industry, taking into account our relative performance, our strategic objectives, and the performance of the individual executive.
Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:
Provide market competitive compensation and benefit levels that will attract, motivate, reward, and retain a highly talented team of executives within the context of responsible cost management;
Establish a direct link between our financial and operational results and strategic objectives and the compensation of our executives;
42

Table of Contents

Align the interests and objectives of our executives with those of our stockholders by linking our executives’ long-term incentive compensation opportunities to stockholder value creation and their cash incentives to our annual performance; and
Offer total compensation opportunities to our executives that, while competitive, are internally consistent.
Executive Compensation Design; Pay for Performance
The annual compensation arrangements for our Named Executive Officers consist of both fixed and "at risk" compensation elements which have been designed to align pay and performance.
Our fixed base salaries are designed to retain our executives by providing dependable and competitive annual income. In addition, we emphasize variable compensation through our short-term incentive cash bonus plan based on our Named Executive Officers attainment of pre-established short-term financial targets as determined from time to time by the Company and reviewed by our Board of Directors in connection with our annual operating plan, and "at-risk" compensation through our long-term equity incentive plan, which has historically consisted of service-vesting RSUs.
Given our brief operating history and status as a public company and as a result of the uncertainty in the macro-economy in 2021 caused by the COVID-19 pandemic, we believe that service-based RSU awards have been an appropriate long-term incentive compensation vehicle in so far as they expose our Named Executive Officers to fluctuations in our stock price, thereby aligning the interests of our Named Executive Officers and stockholders and incentivizing them to build sustainable long-term value for the benefit of our stockholders while satisfying our retention objectives. However, in 2022 we have determined to incorporate PRSUs in our long-term incentive plan as a portion of our long-term incentive grants in order to further tie pay to performance. For 2022, PRSUs make up 25% of the total grant date fair value of the long-term incentive grants for our Named Executive Officers.
These at-risk pay elements ensure that a substantial portion of our Named Executive Officers’ target total direct compensation is contingent (rather than fixed) in nature, with the amounts ultimately payable commensurate with our actual performance.

Base Salary
In February 2021, the Compensation Committee reviewed the base salaries of our Named Executive Officers, taking into consideration a competitive market analysis prepared by its compensation consultant and the recommendations of our CEO (except with respect to the CEO's own compensation), as well as the other factors described in “Compensation-Setting Process" below. Following this review, the Compensation Committee determined to adjust the base salaries of our Named Executive Officers to reflect current market positioning.

The base salaries of our Named Executive Officers were as follows:

Mr. Yoran$450,000 $470,000 4.4 %
Mr. Vintz375,000 400,000 6.7 %
Mr. Riddick330,000 360,000 9.1 %
The base salaries paid to our Named Executive Officers during 2021 are set forth in the Summary Compensation Table below.
Cash Bonuses
Cash bonuses are based upon a specific percentage of each participant’s annual base salary and are paid, subject to goal attainment, in five equally weighted installments, one following each quarter and the fifth payment following year-end.
We believe that paying bonuses throughout the year is the most effective way to motivate achievement of our short-term financial goals because quarterly and annual payments align with the time periods for which we provide external guidance to the investment community.
2021 Cash Bonus Structure
In February 2021, the Compensation Committee reviewed the target short-term cash incentive bonus opportunities of our Named Executive Officers in place for 2021, taking into consideration a competitive market analysis prepared by its compensation consultant and the recommendations of our CEO (except with respect to his own bonus opportunity), as well as the other factors described in “Compensation-Setting" below. Following this review, the Compensation Committee determined to increase the target short-term cash incentive bonus opportunity of Mr. Vintz from 86.7% to 87.5%.
Accordingly, the target short-term cash incentive bonus opportunities of our Named Executive Officers for 2021 were as follows:
Named Executive Officer2021 Target Cash Bonus OpportunityTarget Percentage of Base Salary
Mr. Yoran$470,000 100.0 %
Mr. Vintz350,000 87.5 %
Mr. Riddick180,000 50.0 %
Consistent with the prior year, for 2021, our Board of Directors established anticipated target goals for each performance metric used in our annual operating plan, with actual bonus payments at each periodic payment interval calculated by multiplying 20% of a participant’s target cash bonus opportunity by the weighted average percentage attainment level of the applicable goals for each applicable quarter or full year. No payments are made if attainment is below 75%. Accordingly, for

(2)    We have chosen not to disclose the various target performance levels for our bookings performance measure as such information is proprietary in nature, the disclosure of which could result in competitive harm to the Company. For 2021, the Board of Directors considered the target performance achievement levels for the Board Metrics to be challenging but achievable with significant effort requiring circumstances to align as projected. The bookings target goal reflected an approximate 20% increase over our actual bookings results from 2020.
For this purpose, each of the above metrics are defined as follows:
Revenue - to be calculated in accordance with GAAP and as set forth in our quarterly and annual financial statements.
Unlevered Free Cash Flow – to be calculated as free cash flow, defined as GAAP net cash flows from operating activities reduced by purchases of property and equipment, plus cash paid for interest and other financing costs.
Bookings - to be calculated as sales of new and renewal subscription licenses, perpetual licenses and related first-year maintenance, and services and training, which are closed in a period. Bookings is based on annual contract value (ACV), whereby we include only the first-year contract value as booked in cases where a multi-year deal is prepaid or billed upfront.
Our Board of Directors believed that, for purposes of the short-term cash incentive bonus plan, these were the most appropriate corporate performance measures to use because, in its view, they would provide meaningful indicators of our successful execution of our annual operating plan and our ability to enhance long-term value creation. In particular, we believe our bookings levels is an effective measure of annual contract value, which management uses to measure the growth of our business.
2021 Cash Bonus Attainment
Our actual performance against the aggregate target level for the various corporate performance measures for each quarter and for the full year, as applicable, as well as the amounts received by each Named Executive Officer, were reviewed by the Compensation Committee in February 2021.

Long-Term Incentive Compensation
In February 2021, as part of its annual compensation review the Compensation Committee determined to grant equity awards to our Named Executive Officers in the form of service-based RSU awards consistent with prior years. RSU awards serve as an incentive that is aligned with the long-term interests of our stockholders because their value increases (or decreases) with any change in the value of the underlying shares. Further, RSUs serve our retention objectives because they are subject to a multi-year vesting requirement based on continued service.
Based upon a review of competitive market practice and the incentive power of these awards, in February 2021, the Compensation Committee granted RSU awards to our Named Executive Officers in amounts that it considered to be consistent with our compensation philosophy and its desired market competitiveness as follows:
Named Executive OfficerRestricted Stock Unit Award (shares)Restricted Stock Unit Award (grant date fair value)Year-over-Year Change
Mr. Yoran171,037$7,500,000 13.6 %
Mr. Vintz93,5004,100,000 2.5 %
Mr. Riddick50,1712,200,000 22.2 %
The RSU awards granted to our Named Executive Officers vest over a four-year period, with 25% of the total number of units subject to the award vesting on the first anniversary of February 17, 2021, the vesting commencement date, and 1/16th of the total number of units subject to the award vesting in quarterly installments over the following three years, contingent upon the Named Executive Officer’s continued employment by us through each applicable vesting date.
The equity awards granted to our Named Executive Officers in 2021 are set forth in the “Summary Compensation Table” and the “Grants of Plan-Based Awards Table” below.
Health and Welfare, Retirement and ESPP Benefits
Our Named Executive Officers are eligible to receive the same health and welfare benefits that are generally available to all full-time, salaried employees, subject to the satisfaction of certain eligibility requirements, including medical, dental, and vision insurance, business travel insurance, an employee assistance program, health and dependent care flexible spending accounts, basic life insurance, accidental death and dismemberment insurance, short-term and long-term disability insurance, commuter benefits, and reimbursement for mobile phone coverage.
Our Named Executive Officers are also eligible to participate in our 401(k) retirement plan (the “Section 401(k) Plan”) that provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. For 2021, during each pay period, we made matching contributions to all participating employees for each $1.00 of an employee’s contribution, up to a maximum of 4% of the employee’s eligible earnings, subject to annual limitations.
We provide additional long-term equity incentives through the 2018 Employee Stock Purchase Plan (the “ESPP”), which became effective in connection with our initial public offering in July 2018. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Code. Generally, all of our regular employees (including our Named Executive Officers during their employment with us) may participate in the ESPP and may contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of our common stock. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Each offering will
49

Table of Contents

have one or more purchase dates on which our common stock will be purchased for employees participating in the offering. Unless otherwise determined by our Compensation Committee, shares are purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of our common stock on the first date of an offering or (b) 85% of the fair market value of our common stock on the date of purchase.
Perquisites and Other Personal Benefits
Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not offer perquisites or other personal benefits to our Named Executive Officers, apart from those generally made available to our employees or in situations where we believe it is appropriate to assist an individual in the performance of his or her duties, to make him or her more efficient and effective, and for recruitment and retention purposes. During 2021, none of our Named Executive Officers received perquisites or other personal benefits that were, in the aggregate, $10,000 or more for each individual.
Compensation-Setting Process
Role of Compensation Committee
The Compensation Committee discharges the responsibilities of our Board of Directors relating to the compensation of our Named Executive Officers, including by overseeing our compensation and benefits policies generally, and overseeing and evaluating the compensation plans, policies, and practices applicable to our CEO and other Named Executive Officers. In so doing, the Compensation Committee reviews our Named Executive Officers’ base salary levels, cash bonus targets, and long-term incentive compensation of our Named Executive Officers and all related performance criteria at the beginning of each year, or more frequently as warranted. Compensation adjustments to base salary are generally effective on March 1 and changes to target bonus amounts are generally effective at the beginning of the year. The Compensation Committee also makes compensation recommendations for the non-employee members of our Board of Directors to our full Board of Directors for their review and approval.
The Compensation Committee retains a compensation consultant (as described below) to provide support in its review and assessment of our executive compensation program.
Factors Used in Determining Executive Compensation
In making decisions about the compensation of our Named Executive Officers, the members of the Compensation Committee do not establish a specific target or benchmark against our peers for each executive and instead take a holistic approach, relying primarily on their general experience and consideration of various factors, including the following:
our executive compensation program objectives;
our performance against the financial, operational, and strategic objectives established by the Compensation Committee and our Board of Directors;
each individual Named Executive Officer’s knowledge, skills, experience, qualifications, and tenure relative to other similarly situated executives at the companies in our compensation peer group;
the scope of each Named Executive Officer’s role and responsibilities compared to other similarly situated executives at the companies in our compensation peer group;
50

Table of Contents

the prior performance of each individual Named Executive Officer, based on a subjective assessment of his or her contributions to our overall performance, ability to lead his or her business unit or function, and work as part of a team, all of which reflect our core values;
the potential of each individual Named Executive Officer to contribute to our long-term financial, operational, and strategic objectives;
the value of each Named Executive Officer's target total direct compensation opportunity (the sum of base salary, cash bonus opportunity and equity awards);
our financial performance relative to our peers;
the compensation practices of our compensation peer group and the positioning of each Named Executive Officer’s compensation in a ranking of peer company compensation levels based on an analysis of competitive market data; and
the recommendations of our CEO with respect to the compensation of our Named Executive Officers (except with respect to his own compensation).
The Compensation Committee does not weigh these factors in any predetermined manner or formulaically, nor is any single factor determinative in setting compensation levels or making compensation decisions. In addition, we have not adopted any formal policies or employed guidelines for allocating compensation between current and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation. Instead, the members of the Compensation Committee consider the above and other information in light of their individual experience, knowledge of the Company, knowledge of the competitive market, knowledge of each Named Executive Officer, and business judgment in making their decisions.
Role of Management
In discharging its responsibilities, the Compensation Committee works with members of our management who provide information on corporate and individual performance, market compensation data, and other compensation related matters.
In addition, our Compensation Committee seeks the CEOs input with respect possible adjustments to annual cash compensation, long-term incentive compensation opportunities and other compensation-related matters for our non-CEO Named Executive Officers based on his evaluation of such Named Executive Officers’ performance for the prior year. Our CEO also attends meetings of our Board of Directors and the Compensation Committee at which executive compensation matters are addressed, but is not present during discussions involving his own compensation.
Role of Compensation Consultant
The Compensation Committee has retained an independent compensation consultant, Compensia, to advise on executive compensation matters, including competitive market pay practices for our Named Executive Officers, and to assist with the data analysis and development of the compensation peer group. During 2021, Compensia attended the meetings of the Compensation Committee (both with and without management present) as requested and provided various services to assist the committee in carrying out its duties. Under this engagement, Compensia reported directly to the Compensation Committee chair and also coordinated with our management for data collection and job matching for our executives. In 2021, Compensia did not provide any other services to us.
In 2021, the Compensation Committee evaluated the independence of Compensia and, based on this review, determined that no conflict of interest was raised as a result of the work performed by Compensia. In reaching this conclusion, the Compensation Committee considered applicable SEC rules and regulations and the corresponding Nasdaq independence factors regarding compensation advisor independence.

Risk Management
Each year, with the help of our independent compensation consultant, our Compensation Committee reviews whether our compensation policies and practices encourage executives or other employees to take unnecessary or unreasonable risks that could threaten the long-term value of the Company, or that are reasonably likely to have a material adverse effect. The Compensation Committee believes that our practices adequately manage this risk in so far as it:
adopts an appropriate pay philosophy,
uses an appropriate, objectively selected peer group to support decision-making,
reflects risk-mitigating design and governance practices in key areas,
incentivizes execution on our business strategy,
is appropriately balanced, with potential for reward based on long term company performance, and
reviews actual pay delivery from performance-based incentives to confirm the rigor of goal setting and the alignment with performance.
Competitive Positioning
For purposes of assessing our executive compensation against the competitive market, the Compensation Committee reviews and considers the compensation levels and practices of a select group of peer companies as well as data drawn from the Radford Global Technology Survey. The Compensation Committee reviews our compensation peer group at least annually with the assistance of Compensia and makes adjustments to its composition if warranted, taking into account changes in both our business and the businesses of the companies in the peer group.
When reviewing the peer group, Compensia and the Compensation Committee use the following criteria to identify companies reasonably similar to us in terms of revenue, market capitalization, and industry focus:
publicly traded companies headquartered in the United States and traded on a major United States stock exchange;
companies in the information technology sector;
companies with similar revenues - within a range of approximately 0.33x to approximately 3.0x of our last four quarters' revenue of approximately $380 million (approximately $130 million to $1.1 billion)
companies with similar market capitalizations - within a range of approximately 0.33x to approximately 3.0x of our then-projected market capitalization of approximately $3 billion (approximately $1 billion to approximately $9 billion);
companies in the Internet/network security software sector; and
companies with revenue growth generally greater than 20%.

Employment Arrangements
In February 2019, we entered into amended and restated written employment agreements with each of our named executive which superseded each officer’s prior employment agreement. These amended and restated employment agreement reflect a standardized approach for the payment of severance and change in control payments and benefits to our Named Executive Officers. Under this approach, the post-employment compensation arrangements of our Named Executive Officers were established on a uniform basis and at levels that generally align with current market practice.
For detailed descriptions of the amended and restated employment agreements with our Named Executive Officers, see “Potential Payments upon Termination or Change in Control” below.
Post-Employment Compensation
Under their amended and restated employment agreements, our Named Executive Officers are eligible for certain benefits in the event of their termination of employment by virtue of death or disability and in the event of an involuntary termination of employment, including an involuntary termination of employment in connection with a change in control of the Company. We believe that these benefits are representative of market practice and therefore are necessary to motivate and retain our Named Executive Officers.
These arrangements provide reasonable compensation to the Named Executive Officer if he or she leaves our employ under certain circumstances to facilitate his or her transition to new employment. Further, in some instances we seek to mitigate any potential employer liability and avoid future disputes or litigation by requiring a departing Named Executive Officer to execute and deliver an effective general release of claims in favor of the Company in a form acceptable to us as a condition to receiving post-employment compensation payments or benefits. We also believe that these arrangements help maintain the continued focus and dedication of our Named Executive

Officers to their assigned duties to maximize stockholder value if there is a potential transaction that could involve a change in control of the Company.
Under the amended and restated employment agreements, all payments and benefits in the event of a change in control of the Company are payable only if there is a subsequent loss of employment by a Named Executive Officer (a so-called “double-trigger” arrangement). In the case of the acceleration of vesting of outstanding equity awards, we use this double-trigger arrangement to protect against the loss of retention value following a change in control of the Company and to avoid windfalls, both of which could occur if vesting of either equity or cash-based awards accelerated automatically as a result of the transaction.
We do not use excise tax payments (or “gross-ups”) relating to a change in control of the Company and have no such obligations in place with respect to any of our Named Executive Officers.
We believe that having in place reasonable and competitive post-employment compensation arrangements, including in the event of a change in control of the Company, are essential to attracting and retaining highly qualified executives. The Compensation Committee does not consider the specific amounts payable under the post-employment compensation arrangements when determining the annual compensation for our Named Executive Officers. We do believe, however, that these arrangements are necessary to offer compensation packages that are competitive.
For detailed descriptions of the post-employment compensation arrangements with our Named Executive Officers, as well as an estimate of the potential payments and benefits payable under these arrangements, see “Potential Payments upon Termination or Change in Control” below.
Other Compensation Policies
Hedging and Pledging Prohibitions
Under our Insider Trading Policy, our employees (including officers), members of our Board of Directors, and consultants are prohibited from engaging in short sales, transactions in put or call options, hedging transactions, margin accounts, pledges, or other inherently speculative transactions with respect to our stock.
Stock Ownership Guidelines
The Compensation Committee believes that stock ownership guidelines help align the interests of our non-employee directors with those of our stockholders and may act as a risk mitigation device. In February 2022, our Compensation Committee adopted stock ownership guidelines for our non-employee directors. The Compensation Committee believes that stock ownership guidelines help align the interests of our non-employee directors with those of our stockholders and may act as a risk mitigation device. Under these guidelines, the non-employee members of our Board are each required to beneficially own shares of our common stock with a value equal to at least five times their annual cash retainer.
Compensation Recoupment Policy
In February 2022, our Board of Directors adopted a compensation recoupment (or “clawback”) policy. This policy permits the Compensation Committee, if it determines appropriate and subject to applicable laws, to seek reimbursement of incentive compensation if we are required to restate incorrect financial statements and the executive’s (including each Named Executive Officer’s) misconduct contributed to the noncompliance that results in the obligation to restate the financial

Table of Contents

statements. Under this policy, the Compensation Committee may seek recoupment of the following incentive compensation received during the three years preceding the date we are required to prepare the accounting restatement (but after adoption of the policy):
the incremental portion of any cash incentive awards paid based on the financial statements that were subsequently restated in excess of the lower cash incentive awards that would have been paid had the financial statements been properly reported;
the incremental portion of any equity incentive awards that were received based on the financial statements that were subsequently restated in excess of the portion that would have been earned had the financial statements been property reported; and
if the executive sells any shares acquired pursuant to an equity incentive award after the release of earnings for any period with respect to which financial statements are subsequently restated but prior to the announcement of the restatement, the incremental value of the sales proceeds received form the executive’s sale of those shares over the aggregate sales proceeds the executive would have received from the sale at a price per share determined appropriate by the Compensation Committee in its discretion to reflect what our common stock price would have been if the restatement had occurred prior to the date sale. Our stock incentive plans and executive employment agreements also provide for forfeiture of equity awards and severance if an executive is terminated for cause, including misconduct that results in reputational harm to the Company.
Tax and Accounting Considerations
The Compensation Committee takes the applicable tax and accounting requirements into consideration in designing and overseeing our executive compensation program.
Deductibility of Executive Compensation
In determining executive compensation, the Compensation Committee also considers, among other factors, the possible tax consequences to the company and to its executives. To maintain maximum flexibility in designing compensation programs, the Compensation Committee, while considering company tax deductibility as one of its factors in determining compensation, will not limit compensation to those levels or types of compensation that are intended to be deductible.
Generally, Section 162(m) of the Code as amended by the Tax Cuts and Jobs Act of 2017 (the “TCJA”) disallows public companies a tax deduction for federal income tax purposes of remuneration in excess of $1 million. However, under a transition rule that applies to companies that become subject to Section 162(m) by reason of becoming publicly held, certain compensation is exempt from the deduction limit if it was: granted during a transition period (and, with respect to RSU awards, that are paid out before the end of the transition period), is paid under a compensation arrangement that was in existence before the effective date of a company's initial public offering and was disclosed in the company’s public filings at the time of its initial public offering, subject to certain other requirements and limitations. We currently expect our transition period to expire at our 2022 annual meeting.
Accounting for Stock-Based Compensation
The Compensation Committee takes accounting considerations into account in designing compensation plans and arrangements for our executives and other employees. Chief among these is Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“ASC Topic
55

Table of Contents

718”), the standard which governs the accounting treatment of certain stock-based compensation. Among other things, ASC Topic 718 requires us to record a compensation expense in our income statement for all equity awards granted to our executives and other employees. This compensation expense is based on the grant date “fair value” of the equity award and, in most cases, will be recognized ratably over the award’s requisite service period (which, generally, will correspond to the award’s vesting schedule). This compensation expense is also reported in the compensation tables below, even though recipients may never realize any value from their equity awards.

(1)     This column reflects the aggregate grant date fair value of RSUs granted during the year measured pursuant to ASC Topic 718. This calculation assumes that the Named Executive Officer will perform the requisite service for the award to vest in full as required by SEC rules. These amounts do not reflect the actual economic value that will be realized by the Named Executive Officer upon vesting of the RSU or the sale of common stock underlying such RSUs. The assumptions we used in valuing RSUs are described in Note 10 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021.
(2)    These amounts reflect the cash awards paid under the short-term cash incentive bonus plan for performance during the applicable year. See the Compensation Discussion and Analysis for a more complete description of how the cash bonuses were determined for the year ended December 31, 2021.

coverage for 12 months following termination, and a lump sum cash payment equal to the Named Executive Officer’s target annual bonus reduced by the amount of the quarterly bonuses paid during 2021.
(4)    Represents the value of a lump sum cash payment equal to 12 months of base salary (18 months for Mr. Yoran), payment by the company of the employer-paid portion of premiums for continued group health coverage for 12 months following termination, a lump sum cash payment equal to one times the Named Executive Officer’s target annual bonus (1.5 times for Mr. Yoran) reduced by the amount of the quarterly bonuses paid during 2021, and a lump sum cash payment equal to one times the Named Executive Officer’s target annual bonus (1.5 times for Mr. Yoran).
CEO Pay Ratio
Under the Dodd-Frank Wall Street Reform and Consumer Protection Act and SEC rules, we are required to provide a reasonable estimate of the ratio of the annual total compensation of Mr. Yoran, our Chief Executive Officer, to the median of the annual total compensation of our other employees. In accordance with Instruction 2 to Item 402(u) of Regulation S-K under the Securities Act of 1933, as amended, because there has been no change in our employee population or employee compensation arrangements in the last year that we reasonably believe would result in a significant change to our pay ratio disclosure, we elected to utilize the same median employee we had identified in 2020 to calculate our 2021 CEO pay ratio. For our last completed year, which ended December 31, 2021:
The median of the annual total compensation of all of our employees (other than Mr. Yoran), including employees of our consolidated subsidiaries, was approximately $176,067. This annual total compensation is calculated in accordance with Item 402(c)(2)(x) of Regulation S-K, and reflects, among other things, salary and bonus earned and aggregate “grant date fair value” of RSU awards granted during 2021.
Mr. Yoran's annual total compensation for 2021, as reported in the Summary Compensation Table included in this Proxy Statement, was $8,480,631.
Based on the above, for 2021, the ratio of Mr. Yoran's annual total compensation to the median of the annual total compensation of all employees was approximately 48 to 1.
This pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Securities Act of 1933, as amended, and applicable guidance and is based upon our reasonable judgment and assumptions. The SEC rules do not specify a single methodology for identification of the median employee or calculation of the pay ratio, and other companies may use assumptions and methodologies that are different from those used by us in calculating their pay ratio. Accordingly, the pay ratio disclosed by other companies, even companies within the same industry as us, may not be comparable to our pay ratio as disclosed above.
The methodology, including any material assumptions, adjustments and estimates, we used to calculate identify the median employee and calculate the 2021 pay ratio is described below.
For purposes of the pay ratio calculation, we included substantially all of our full-time, part-time and temporary employees globally as of December 31, 2020. As permitted by the SEC rules, we excluded 5% of our global employee population from the calculation by excluding all employees in a given jurisdiction located outside of the United States, starting with the jurisdiction that had the lowest number of employees as of December 31, 2020, and continuing to exclude all employees in jurisdictions with an increasingly greater number of employees as of such date until 5% of our total global employee population was excluded.
62

Table of Contents

We excluded these employees given the small number of employees in those jurisdictions and the estimated cost of obtaining their compensation information. As of December 31, 2020, our workforce consisted of 1,301 employees (including individuals employed by our consolidated subsidiaries), 912 of whom were U.S. employees, and 389 (or approximately 30% of our total employee population as of December 31, 2020) were employees located outside of the United States, after excluding 66 employees located outside the United States via the methodology described above.
To identify the median employee from the employee population described above, we determined the sum of each employee's (i) annual base salary as of December 31, 2020 (calculated as annual base pay using a reasonable estimate of hours worked during 2020 for hourly employees and using annual base salary for our remaining employees), plus (ii) earned annual cash incentive bonus or commission, as applicable, for 2020. Permanent employees who joined in 2020 were assumed to have worked for the entire year, and thus we annualized the pay of such new hires. This compensation measure was consistently applied to all employees included in the calculation and reasonably reflects the annual compensation of all of our employees. Compensation paid in foreign currency was converted to U.S. dollars using a spot exchange rate on December 31, 2020. In determining the median compensated employee, we did not make any cost of living adjustments to the compensation paid to any employee outside of the U.S.
Once we identified our median employee, we calculated the median employee’s annual total compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, including for this purpose the aggregate grant date fair value of equity awards (as determined in accordance with footnote 1 of the 2021 Summary Compensation Table) granted in 2021, yielding the median annual total compensation disclosed above. With respect to Mr. Yoran's annual total compensation, we used the amount reported in the “Total” column of our 2021 Summary Compensation Table.

TRANSACTIONS WITH RELATED PERSONS AND INDEMNIFICATION
Related-Person Transactions Policy and Procedures
We have adopted a related person transaction policy that sets forth our procedures for the identification, review, consideration and approval or ratification of related person transactions. For purposes of our policy only, a related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we and any related person are, were or will be participants in which the amount involved exceeds $120,000. Transactions involving compensation for services provided to us as an employee or director are not covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of our voting securities, including any of their immediate family members and any entity owned or controlled by such persons.
Under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, our management must present information regarding the related person transaction to our Audit Committee, or, if Audit Committee approval would be inappropriate, to another independent body of our Board of Directors, for review, consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to us of the transaction and whether the transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, we will collect information that we deem reasonably necessary from each director, executive officer and, to the extent feasible, significant stockholder to enable us to identify any existing or potential related-person transactions and to effectuate the terms of the policy. In addition, under our Code of Business Conduct and Ethics, our employees and directors have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, our Audit Committee, or other independent body of our Board of Directors, will take into account the relevant available facts and circumstances including, but not limited to:
    the risks, costs and benefits to us; 
    the impact on a director's independence in the event that the related person is a director, immediate family member of a director or an entity with which a director is affiliated; 
    the availability of other sources for comparable services or products; and 
    the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.
The policy requires that, in determining whether to approve, ratify or reject a related person transaction, our Audit Committee, or other independent body of our Board of Directors, must consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, our best interests and those of our stockholders, as our Audit Committee, or other independent body of our Board of Directors, determines in the good faith exercise of its discretion.
Certain Related Person Transactions
The following includes a summary of transactions since January 1, 2021 to which we have been a party, in which the amount involved in the transaction exceeded $120,000, and in which any of our directors, executive officers or, to our knowledge, beneficial owners of more than 5% of our voting securities or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest. Other than described below, there have not been, nor are there

currently any proposed, transactions or series of similar transactions to which we have been or will be a party other than compensation arrangements, which include equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation” and “Director Compensation.”
Employment Arrangements with Messrs. Schonberger and Vintz
We have employed Ron Schonberger, the brother of Amit Yoran, our Chief Executive Officer and Chairman, as our Associate General Counsel since October 2017, and Frank Vintz, the brother of Stephen A. Vintz, our Chief Financial Officer, as a Senior Director of Customer Success since March 2017. Each of Mr. Schonberger and Mr. Frank Vintz is paid compensation consisting of salary, bonus and the fair value of options to purchase common stock or RSUs. In 2021, Mr. Schonberger and Mr. Frank Vintz each received total cash and equity compensation of approximately $400,000.
Transaction Success Fee to Security Growth Partners LLC
On February 17, 2022, Security Growth Partners LLC, or SGP, received a transaction success fee from Cymptom Labs Ltd., or Cymptom, of $690,000 as consideration for services provided to Cymptom to facilitate the sale of Cymptom to Tenable. N. Elad Yoran, the brother of Amit Yoran, our Chief Executive Officer and Chairman, is a member of and affiliated with SGP. The success fee was paid by Cymptom out of the proceeds we paid to acquire Cymptom. The Board reviewed and approved the success fee as a related party transaction in connection with its approval of the acquisition of Cymptom.
Indemnification
We provide indemnification for our directors and executive officers so that they will be free from undue concern about personal liability in connection with their service to the Company. Under our Bylaws, we are required to indemnify our directors and executive officers to the extent not prohibited under Delaware law. We have also entered into indemnity agreements with our executive officers and directors. These agreements provide, among other things, that we will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under Delaware law and our Bylaws.

HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.
This year, a number of brokers with account holders who are our stockholders will be “householding” the Company’s proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please notify your broker or us. Direct your written request to Tenable Holdings, Inc., Attn: Corporate Secretary, 6100 Merriweather Drive, 12th Floor, Columbia, Maryland 21044. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.

APPENDIX
RECONCILIATION OF NON-GAAP MEASURES
In this proxy statement, we discuss certain operating metrics and non-GAAP financial measures, as described below, which we think are important to better understand and evaluate our core operating and financial performance. These non-GAAP financial measures, which may be different than similarly titled measures used by other companies, are presented to enhance the overall understanding of our financial performance and should not be considered a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP included in our Annual Report on Form 10-K. We believe that these operating metrics and non-GAAP financial measures provide useful information about our operating and financial performance, enhance the overall understanding of our past performance and future prospects and allow for greater transparency with respect to important metrics used by management for financial and operational decision-making.
Calculated Current Billings
We define calculated current billings, a non-GAAP financial measure, as total revenue recognized in a period plus the change in current deferred revenue in the corresponding period. We believe that calculated current billings is a key metric to measure our periodic performance. Given that most of our customers pay in advance (including multi-year contracts), but we generally recognize the related revenue ratably over time, we use calculated current billings to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers. We believe that calculated current billings, which excludes deferred revenue for periods beyond twelve months in a customer’s contractual term, more closely correlates with ACV and that the variability in total billings, depending on the timing of large multi-year contracts and the preference for annual billing versus multi-year upfront billing, may distort growth in one period over another.
The following table presents a reconciliation of revenue, the most directly comparable financial measure calculated in accordance with GAAP, to calculated current billings:
Year Ended December 31,
(in thousands)20212020
Revenue$541,130 $440,221

Calculated current billings$617,166 $494,692 
_______________
(1)    Deferred revenue (current), beginning of period for 2021 includes $2.6 million related to acquired deferred revenue, which is not included in deferred revenue at December 31, 2020.
Free Cash Flow, Unlevered Free Cash Flow and Unlevered Free Cash Flow Margin
We define free cash flow, a non-GAAP financial measure, as net cash provided by operating activities less purchases of property and equipment. We believe free cash flow is an important liquidity measure of the cash (if any) that is available, after purchases of property and equipment, for investment in our business and to make acquisitions. We believe that free cash flow is useful as a liquidity measure because it measures our ability to generate or use cash.
We also use the non-GAAP measure of unlevered free cash flow, which we define as free cash flow plus cash paid for interest and other financing costs. We believe unlevered free cash flow is useful as a liquidity measure as it measures the cash that is available to invest in our business and

meet our current and future financing needs. Unlevered free cash flow margin is defined as unlevered free cash flow as a percentage of revenue.
The following table presents a reconciliation of net cash provided by operating activities, the most directly comparable financial measure calculated in accordance with GAAP, to free cash flow and unlevered free cash flow:
Year Ended December 31,

Acquisition-related expenses(6.5)(0.7)
Tax payment on intra-entity transfer2.8 — 
Proceeds from lease incentives— 14.2 
Capital expenditures related to new headquarters(0.9)(17.2)
Free cash flow and unlevered free cash flow in 2021 were reduced by approximately $8 million due to prepayments of software subscription costs, insurance and rent, offset by a benefit of approximately $15 million from prepayments of similar items made in 2020. The 2020 prepayments reduced free cash flow and unlevered free cash flow by approximately $17 million in 2020.
Non-GAAP Income from Operations
We use non-GAAP income from operations as a key indicator of our financial performance. We define non-GAAP income from operations as loss from operations, excluding the effects of stock-based compensation, acquisition-related expenses and amortization of acquired intangible assets. Acquisition-related expenses include transaction expenses and costs related to the intercompany transfer of acquired intellectual property.

Non-GAAP Net Income and Non-GAAP Earnings Per Share
We use non-GAAP net income, which excludes the effect of stock-based compensation, acquisition-related expenses and amortization of acquired intangible assets, including the applicable tax impacts, and the tax impact of intra-entity asset transfers resulting from the internal restructuring of legal entities as well as deferred income tax benefits recognized in connection with acquisitions, to calculate non-GAAP earnings per share. We believe that these non-GAAP measures provide important information to management and investors because they facilitate comparisons of our core operating results over multiple periods.
