CTA intelligence sharing is grounded in 5 guiding principles
FOR THE GREATER GOOD
We protect customers, strengthen critical infrastructure, and defend the digital ecosystem.
TIME IS OF THE ESSENCE
We prevent, identify, and disrupt malicious activity by rapidly sharing timely, actionable intelligence.
We reward context sharing to identify an indicator and provide useful information about it.
We attribute intelligence to the member who submits it, but anonymize any and all victim and sensitive data.
YOU MUST GIVE TO RECEIVE
We require all members to share a minimum amount of intelligence with the alliance to prevent the free-rider problem.
