Homeland Security Components

Homeland Security Information Network

HSIN is a comprehensive, nationally secure and trusted web-based platform able to facilitate Sensitive But Unclassified (SBU) information sharing and collaboration between federal, state, local, tribal, private sector, and international partners. The HSIN platform was created to interface with existing information sharing networks to support the diverse Communities of Interest (COI) engaged in preventing, protecting from, responding to, and recovering from all threats, hazards and incidents under the jurisdiction of the Department of Homeland Security.

Built to enable collaboration through the use of web-based technology, HSIN facilitates collaboration among the various states, territories, the National Capital Region, and major urban areas. HSIN supports Department components and partners in the gathering, analysis and distribution of relevant, timely, and actionable mission-focused information across federal, state, and local government, and private industry COIs.

A key by-product of HSIN is the ability to provide real-time, interactive connectivity between states and major urban areas and the National Operations Center (NOC). HSIN is focused on providing a collaborative environment that interoperates with existing mission area systems developed and managed by our federal, state and local partners. HSIN is focused on enhancing collaboration rather than duplicating the capabilities provided by our partners. As a result of its unique perspective, HSIN facilitates collaboration between mission areas such as Law Enforcement, Emergency Management, and Critical Sectors.

Mission Areas

HSIN has five major mission areas which allow local, state, and federal organizations, private sector partners, critical sector organizations like utility companies, fusion centers and government agencies with multi-missions to collaborate on HSIN everyday:

By using HSIN, these diverse communities are able to work together to perform investigations, identify terrorist activities, respond to areas affected by natural disasters and provide coordination during recovery operations.
