​Our Mission

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.

​State Threat Assessment Center Facts

  • The California State Threat Assessment Center was built as a direct result of the events of 9/11, and the national information sharing deficiencies preceding it.

  • In 2004, the Governor’s Office of Emergency Services (Cal OES), formerly the Governor’s Office of Homeland Security (OHS), developed a plan as a part of its homeland security strategy to establish one major urban area and five regional fusion centers to establish the State Threat Assessment System (STAS).

  • The STAC serves as the state-level partner of the locally owned and operated fusion centers in Sacramento, San Francisco, Los Angeles, Orange County and San Diego.

  • In 2009, the STAC formalized its partnership through a Memorandum of Understanding between California Department of Justice, Cal OES, and California Highway Patrol; the latter vested with the day-to-day command and management of the STAC.

  • The California National Guard, the California Police Chiefs Association, the California Sheriffs Association and the California Department of Corrections and Rehabilitation joined the STAC’s Governance Board in 2013.

​STAC Privacy Policy

Vitally important to the success of the STAC and its mission is its ability to protect and preserve the integrity of the privacy rights and civil liberties of the people of the State of California. To that end, all STAC activities are informed by, and guided through, strict adherence to all applicable state and federal laws, information sharing guidelines, policies and regulations.

​​Suspicious Activity Reporting

STAS members routinely receive tips, leads, or other reports of suspicious activities. Depending on the nature of the information, and particularly when credible information indicates a potential danger to life and property, the STAS member may report the information to CRP, CalOES and other governmental entities with law enforcement, counterterrorism, or national security responsibilities.

The STAC does not conduct investigative activity based on tips, leads or suspicious activity reports.

California's Threat Domains

The STAC produces tailored all-source strategic intelligence designed to alert and inform California's policymakers and other public safety personnel on the numerous threats facing the state every day.

We focus our analyses on the following threats:

  • International and domestic terrorism;
  • Transnational crime (including countering illicit narcotics trafficking, and human trafficking);
  • Criminal gangs;
  • Criminal domestic extremist movements;
  • Cybercrimes (including threats from state and non-state actors);
  • Threats to California's critical infrastructure and key resources; and,
  • Threats developing from emerging and disruptive technologies.
