National Security Branch


Uniting the capabilities of the FBI’s national security operations into a single, seamless force...

The National Security Branch (NSB)—created in September 2005 in response to a presidential directive—combines the missions and resources of our counterterrorism, counterintelligence, and weapons of mass destruction elements under the leadership of a senior Bureau official. It also includes the Terrorist Screening Center, which plays a crucial role in providing actionable intelligence to state and local law enforcement, and the High-Value Detainee Interrogation Group, which gathers and applies the nation’s best resources to collect intelligence from key terror suspects to prevent attacks against the U.S. and its allies.
