State Threat Assessment System

Law Enforcement





The California State Threat Assessment System (STAS) - California’s Fusion Center network - is led by the California State Threat Assessment Center (STAC), California’s primary Fusion Center as designated by the Governor. The STAS is a key prevention component of the statewide Homeland Security Strategy. The STAS assists in the detection, prevention, investigation, and response to criminal and terrorist activity, disseminates intelligence, shares information, and facilitates communications between tribal, local, state, and federal agencies and private sector partners, to help address critical threats and public safety issues facing California.


The STAS is comprised of the STAC, four Regional Threat Assessment Centers, and one Major Urban Area Intelligence Center:


The STAS is designed to detect, deter, and prevent homeland security threats to the citizens and critical infrastructure of California. It fosters a collaborative effort to enhance the reporting, tracking, analysis, and assessment of criminal threat information and suspicious activities; produces and shares timely and actionable homeland security information; and, enhances the safety of the citizens of California, while rigorously protecting their privacy, civil rights, and civil liberties.

The STAS refrains from investigating or reporting on First or Second Amendment activity unless such activity is illicit, illegal, or otherwise poses a threat to public safety. Civil liberties and the privacy of citizens of the state are considered paramount in all STAS activities.
