The State Threat Assessment Center (STAC) serves as California’s information sharing clearinghouse of strategic threat analysis and situational awareness reporting to statewide leadership and the public safety community in support of efforts to prevent, prepare for, mitigate and respond to all crimes and all hazards impacting California citizens and critical infrastructure, while preserving civil liberties, individual privacy, and constitutional rights.

The State Threat Assessment Center (STAC) is California’s state primary fusion center, as designated by the Governor of California, and is operated by the California Highway Patrol (CHP), the California Governor’s Office of Emergency Services (Cal OES), and the California Department of Justice (Cal DOJ).

The STAC Consists of three teams:

  • Awareness Response (ART ) Team
    The ART Team is the center’s hub for sharing information concerning ongoing events.
  • Strategic Analysis (STRAT) Team
    The STRAT Team analyzes trends in homeland secuirty.
  • Critical Infrastructure (CIP) Team
    The CIP Team coordinates state efforts to identify, prioritize and protect critical infrastructure.

The State Threat Assessment System (STAS) helps safeguard the communities of California by serving as a dynamic security nexus comprised of the State, four Regional and a major urban area Fusion Center.  The STAS assists in the detection, prevention, investigation and response to criminal and terrorist activity, disseminates intelligence and facilitates communications between state, local, federal, tribal agencies and private sector partners, to help them take action on threats and public safety issues. The STAS is a key component of California’s Homeland Security Strategy.

The CIP unit assesses risk to California’s critical infrastructure. The unit identifies, prioritizes, and helps protect California’s critical assets from natural hazards, technological hazards and human-caused threats. CIP and its partner such as regional fusion centers, the California Cybersecurity Integration Center, and the Department of Homeland Security provide infrastructure owners and operators with threat information, risk reduction options, and other support to help manage risk to their assets and systems.
