City skyline The Homeland Security Information Network (HSIN) is the trusted network for homeland security mission operations to share Sensitive But Unclassified (SBU) information. The Critical Infrastructure community on HSIN (HSIN-CI) is the primary system through which private sector owners and operators, DHS, and other federal, state, and local government agencies collaborate to protect the nation’s critical infrastructure. HSIN-CI provides real-time collaboration tools including a virtual meeting space, document sharing, alerts, and instant messaging at no charge.

Through HSIN-CI, you are able to:

  • Receive, submit, and discuss timely, actionable, and accurate information.
  • Maintain a direct, trusted channel with DHS and other vetted sector stakeholders.
  • Communicate information pertaining to threats, vulnerabilities, security, and response and recovery activities affecting sector and cross-sector operations.
