Not to mention, Threat Intelligence Sharing was a key component listed in President Biden’s Executive Order on cybersecurity.
A company can no longer operate in a silo when cyber adversaries leverage a full range of tactics across multiple industries. Having a broader picture of these actors and their motivations requires sharing threat intelligence that reduces duplication of effort and response time.
