Homeland Security Information Network (HSIN)

The Homeland Security Information Network (HSIN) is the Department of Homeland Security's official system for trusted sharing of Sensitive But Unclassified information between federal, state, local, territorial, tribal, international and private sector partners. Mission operators use HSIN to access Homeland Security data, send requests securely between agencies, manage operations, coordinate planned event safety and security, respond to incidents, and share the information they need to fulfill their missions and help keep their communities safe. For more information about HSIN, please contact HSIN@hq.dhs.gov.
