An intel-driven national security and law enforcement agency, providing leadership and making a difference for more than a century.

Our priority is to help protect you, your children, your communities, and your businesses from the most dangerous threats facing our nation—from international and domestic terrorists to spies on U.S. soil…from cyber villains to corrupt government officials…from mobsters to violent street gangs…from child predators to serial killers. Along the way, we help defend and uphold our nation’s economy, physical and electronic infrastructure, and democracy.
