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 2025 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 3, 2025 to all stockholders of record entitled to vote at the Annual Meeting.

#### Will I receive any other proxy materials by mail?
We may, at our discretion, elect to send you a proxy card. We may also send you a second Notice on or after April 14, 2025.

#### 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. We recommend that you log in a few minutes before the Annual Meeting to ensure that you are logged in when the meeting starts. Online check-in will begin at approximately 12:45 p.m. Eastern Time. Information on how to vote online during the Annual Meeting is discussed below.

Stockholders attending the virtual meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting; however, any questions will need to be submitted in advance of the meeting. In accordance with the rules of conduct, we ask that you limit your submission to one brief question or comment prior to the meeting that is relevant to the Annual Meeting or our business and that such remarks are respectful of your fellow stockholders and meeting participants.
