Joint Cyber Defense Collaborative

No one entity can secure cyberspace alone.

In our globally interconnected world, our critical infrastructure and way of life face a wide array of serious risks with significant real-world consequences. The Cybersecurity and Infrastructure Security Agency established JCDC—the Joint Cyber Defense Collaborative—to unify cyber defenders from organizations worldwide. This diverse team proactively gathers, analyzes, and shares actionable cyber risk information to enable synchronized, holistic cybersecurity planning, cyber defense, and response.
