The Office of Investigations and Counterintelligence conducts a robust counterintelligence program designed to deter, detect, and neutralize the efforts of foreign intelligence services targeting Department of State personnel, facilities, and diplomatic missions worldwide.

The office's counterintelligence division conducts aggressive counterintelligence inquires and counterespionage investigations with other U.S. Government agencies. All counterespionage investigations are conducted in close coordination with the FBI in accordance with their statutory mandate to prosecute instances or allegations of suspected espionage.

The division conducts numerous counterintelligence and security awareness training programs for all U.S. Government personnel requesting or having access to sensitive Department of State facilities and information. All training programs enhance the understanding of both foreign intelligence and espionage threats and countermeasures, and educate employees on the foreign intelligence environment.

In addition, the Bureau relies on a cadre of security engineers to deter, detect, and neutralize attempts by foreign intelligence services to technically penetrate our office buildings and residences. These efforts range from detecting a simple listening device in the wall to countering the most sophisticated electronic eavesdropping devices and systems.
