How It Works
The FBI operates through a combination of field offices, specialized units, and interagency cooperation to investigate crimes and protect national interests. Its structure allows rapid response to threats across the U.S. and abroad.

- Cyber Division: Created in 2002, this unit combats cyberattacks, tracking over 2,000 cyber incidents per day on average.
Comparison at a Glance
The FBI differs significantly from other U.S. agencies in scope, jurisdiction, and function. Below is a comparison of key federal investigative bodies.
| Agency | Founded | Primary Mission | Personnel (approx.) | Notable Focus |
|---|---|---|---|---|
| FBI | 1908 | Federal law enforcement, counterterrorism, counterintelligence | 35,000+ | Nationwide jurisdiction |
| CIA | 1947 | Foreign intelligence gathering | 20,000 | No domestic law enforcement role |
| ATF | 1886 (as ATF in 1972) | Regulating firearms, explosives, alcohol, tobacco | 5,000 | Enforces federal firearms laws |
| DEA | 1973 | Enforcing drug laws | 5,500 | Combats drug trafficking organizations |
