The Homeland Security Information Network (HSIN) is the official platform for the Department of Homeland Security (DHS) to safely share Sensitive but Unclassified (SBU) information. The complex and integrated digital community provides a collaborative workspace for interagency communication and cooperation.
HSIN is a multifaceted network of federal, state, local, tribal, territorial, international and private sector (FSLTTIP) stakeholders. HSIN enables access to Homeland Security data; allows for secure distribution of requests between agencies; and provides the ability to manage operations, coordinate planned event safety and security, respond to incidents, and share the information needed to fulfill mission responses to keep communities safe from impending threats.
Since HSIN’s inception, tens of thousands of users across federal, state, local, tribal, territorial, international, and private sector agencies have made HSIN a part of daily operations, planned events and exercises, incident response, and emergency management in the protection of the homeland.
Across many mission areas, HSIN supports:
- Daily operations, such as those at the National Operations Center
- Planned events, including events like the Super Bowl and F1 Racing Series
- Incident response, such as the Maui Wildfires and Hurricane Helene

In 2024, HSIN marked its 20th anniversary. Today, HSIN continues to serve its partners and stakeholders faithfully, helping them achieve mission success. New people, new processes, and new tools are infusing HSIN every day with new ideas and possibilities.

HSIN Communities of Interest (COIs) are self-selecting, self-governing, secure, web-based sites tailored to meet the information sharing and operational needs of Homeland Security partners. These sites comprise community members (HSIN users) working within a particular mission area and cover a variety of missions such as emergency management, law enforcement, cybersecurity, intelligence, defense, border security, and more.
Example: LA SAFE COI
In Louisiana, HSIN helps law enforcement agencies catalog and track gang activity across jurisdictional boundaries. The State Analytical and Fusion Exchange (LA-SAFE) works with law enforcement agencies across the state to share detailed information about gangs and gang members. HSIN allows sworn members of law enforcement in this community to access this information when and where they need it.
Governance is the set of rules and regulations based on DHS policies that guide HSIN operations and activities. HSIN Governance determines the rules of engagement among all HSIN stakeholders and communities, which lays the foundation for a safe and professional community that engages all users.
