The Cybersecurity Risk Management Committee is currently composed of three directors: Mr. Huffard, Ms. Keane and Mr. Tosheff. All members of the Cybersecurity Risk Management Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq listing rules). The Cybersecurity Risk Management Committee met four times during 2024. The Board has adopted a written Cybersecurity Risk Management Committee charter that is available to stockholders on our website at www.investors.tenable.com .

The Cybersecurity Risk Management Committee meets quarterly and with greater frequency if necessary. The Cybersecurity Risk Management Committee meets regularly in executive session. In addition to one of our co-Chief Executive Officers, our Chief Security Officer and our Chief Legal Counsel regularly attend meetings at the invitation of the Cybersecurity Risk Management Committee. The Cybersecurity Risk Management Committee also has direct access to our Chief Security Officer and evaluates his performance. From time to time, various members of management and other employees as well as outside advisors may be invited by the Cybersecurity Risk Management Committee to brief the committee members on the current threat landscape and cybersecurity efforts. Under its charter, the Cybersecurity Risk Management Committee is granted authority to retain independent advisors and investigate matters brought to its attention.
