Threat Screening Center

About

The Threat Screening Center (formerly Terrorist Screening Center) or the TSC, is a division of the National Security Branch of the Federal Bureau of Investigation (FBI). It is the duty of the TSC to identify suspected or potential terrorists. Though housed within the FBI, the TSC is a multi-agency organization, including representatives from the United States Department of Justice, the United States Department of State, the United States Department of Homeland Security, the United States Department of Defense, the United States Postal Service, and various private contractors. It is located in Vienna, Virginia, near Virginia State Route 123.

Established by presidential directive in the wake of the September 11, 2001 attacks, the TSC's funding and manpower have significantly increased since that time.
