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.
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.
The FBI is the lead agency for exposing, preventing, and investigating intelligence activities, including espionage, on U.S. soil and uses its investigative and intelligence capabilities--as well as strategic partnerships--to pursue spies.
To counter terrorism, the FBI's top investigative priority, we use our investigative and intelligence capabilities to neutralize domestic extremists and help dismantle terrorist networks worldwide.
Born out of the events of September 11, 2001 and created in 2003, the Terrorist Screening Center maintains the U.S. government’s consolidated Terrorist Watchlist—a single database of identifying information about those known to be (or reasonably suspected of being) involved in terrorist activity. By supporting the ability of front-line screening agencies to positively identify known or suspected terrorists trying to obtain visas, enter the country, board aircraft, or engage in other activity, the consolidated Terrorist Watchlist is one of the most effective counterterrorism tools for the U.S. government.
The FBI created the Weapons of Mass Destruction (WMD) Directorate in 2006 to support a cohesive and coordinated approach to incidents involving chemical, biological, radiological, or nuclear (CBRN) material. The Directorate leads U.S. government efforts to prevent and neutralize WMD threats against the homeland and interests abroad by focusing on outreach, intelligence, operational response, and investigative capabilities designed to keep WMD threats from becoming a reality.
