Cyber Information Sharing and Collaboration Program (CISCP)

The U.S. Department of Homeland Security (DHS) Cyber Information Sharing and Collaboration Program (CISCP) enables actionable, relevant, and timely unclassified information exchange through trusted public-private partnerships across all critical infrastructure (CI) sectors. CISCP fosters this collaboration by leveraging the depth and breadth of DHS cybersecurity capabilities within a focused operational context. Through analyst-to-analyst sharing of threat and vulnerability information, CISCP helps partners manage cybersecurity risks and enhances our collective ability to proactively detect, prevent, mitigate, respond to, and recover from cybersecurity incidents. CISCP's overall objective is to build cybersecurity resiliency and to harden the defenses of the United States and its strategic partners.

CISCP Membership Process

It is free to join and use the CISCP program. To become members, prospective partners sign a Cyber Information Sharing and Collaboration Agreement (CISCA), which enables DHS and its partners to exchange anonymized information. Once partners sign the agreement, DHS coordinates an on-boarding session to customize how DHS and the organization can exchange information
