National Security Branch

It’s not just a box on the org chart—it’s a way to unite 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, weapons of mass destruction, and intelligence 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.
