National Security Branch

The FBI created the National Security Branch (NSB) in 2005 in response to a presidential directive to establish a “National Security Service” that combines the missions, capabilities, and resources of the FBI’s national security elements under the leadership of a senior FBI official.

Structure of the NSB 

The traditional distinction between national security and criminal matters is increasingly blurred as terrorists commit crimes to finance their activities and computer hackers create vulnerabilities that can be exploited.The integration of intelligence and investigations makes the FBI uniquely situated to address these threats and vulnerabilities across programs. We draw on both intelligence and law enforcement tools to determine strategically where and when to disrupt threats, and the NSB’s five components work together to accomplish the Branch’s overarching national security mission.
