HSI targets the people, money and materials that support terrorist activities in the U.S. and abroad and is a key player in the global counterterrorism mission.
HSI has special agents assigned across the United States to the FBI’s Joint Terrorism Task Forces (JTTFs), JTTFs are multi-jurisdictional task forces that include federal, state, local, tribal, and territorial law enforcement partners acting as an integrated force to combat terrorism on a national and international scale. HSI participates in a significant percentage of JTTF disruptions of terrorist-related activity each year and has become one of the largest and most productive contributors to the JTTF.
