National Security Branch  banner graphic.

NSB SealSince 9/11, the men and women of the FBI have implemented a comprehensive plan that transforms the organization to enhance our ability to predict and prevent terrorism. We have overhauled our counterterrorism operations, expanded our intelligence capabilities, modernized our business practices and technology, and improved coordination with our federal, state, local, and tribal partners.

The National Security Branch (NSB) was established on 9/12/05, in response to a presidential directive to establish a “National Security Service” that combines the missions, capabilities, and resources of the counterterrorism, counterintelligence, and intelligence elements of the FBI under the leadership of a senior FBI official. In July 2006, the Weapons of Mass Destruction Directorate was created within the NSB to integrate WMD components previously spread throughout the FBI. The NSB also includes the Terrorist Screening Center, which plays a crucial role in providing actionable intelligence to state and local law enforcement.

- Arthur M. Cummings II, Executive Assistant Director, National Security Branch
