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.

What Can You Do About Terrorism?

nctc.jpgTerrorists want you to be afraid. They want you to imagine them in the shadows, to imagine them as something greater than they are. We hope you’ll turn that fear into a healthy awareness of what’s around you, and if you see something suspicious, report it to your local law enforcement agency or submit a tip to the FBI.
