The Cyber Threat Alliance (CTA) is an independent, non-profit membership organization focused on cybersecurity providers. We currently have 34 private-sector members split across across three tiers, and are actively growing our membership to include cybersecurity companies from around the world focused on every element of the ecosystem.

In addition, we are building diverse partnerships with Computer Emergency Response Teams (CERTs), Information Sharing and Analysis Organizations (ISACs), peer non-profits, and other organizations that are not eligible for CTA membership. Visit our Partnerships page to learn more.

Our Membership Programs

CTA has three member categories: Contributing, Affiliate, and Charter. Each requires a different level of commitment in return for a greater say in how the organization is managed and run.

Charter members make the greatest level of commitment to CTA, in terms of both dollars and people. In return, charter members are guaranteed a board seat, participate in the committees that help govern the alliance, and share and receive threat intelligence.

Affiliate members are expected to make a meaningful contribution in terms of dollars and people. The specific membership fee varies depending on the member’s global annual revenue. Affiliate members participate in the operations of the alliance, are eligible to run for a board seat, and share and receive threat intelligence.

Contributing members make a reduced financial contribution to CTA. The specific membership fee varies depending on the member’s global annual revenue. Contributing members share and receive threat intelligence, but are not eligible to sit on the Board or have a designated participant on CTA’s standing committees (aside from Algorithm and Intelligence, which is open to all members).
