The Department of Homeland Security (DHS) is the largest federal law enforcement agency with approximately 80,000 officers across nine agencies and offices. Each day, the Department’s law enforcement officers work to safeguard the nation’s people, property, and ideals.
These are the nine DHS law enforcement agencies and offices:
