#### Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on March 17, 2025 (the "Record Date") will be entitled to vote at the Annual Meeting. On the Record Date, there were 120,191,047 shares of the Company's common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If on March 17, 2025 your shares were registered directly in your name with Tenable’s transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record with respect to those shares and the Notice was sent directly to you by the Company. As a stockholder of record, you may vote online during the meeting or vote by proxy. Whether or not you plan to attend the Annual 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 17, 2025 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 that organization on how to vote the shares in your account. You will receive instructions from the organization 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 the organization.

#### What am I voting on?
There are three matters scheduled for a vote:

• Election of two 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, 2025 (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).
