Bureau of Diplomatic Security
In 1916, Secretary of State Robert Lansing appointed the U.S. Department of State’s first special agents as part of World War I-era security measures. Today, the men and women of the Diplomatic Security Service (DSS) continue their work as part of a global force providing a safe and secure environment for the conduct of U.S. foreign policy.

The Bureau of Diplomatic Security (DS) is the security and law enforcement arm of the U.S. Department of State. DS is a world leader in international investigations, threat analysis, cyber security, counterterrorism, security technology, and protection of people, property, and information.
The Bureau is responsible for providing a safe and secure environment for the conduct of U.S. foreign policy. Every diplomatic mission in the world operates under a security program designed and maintained by Diplomatic Security. In the United States, Diplomatic Security personnel protect the Secretary of State and high-ranking foreign dignitaries and officials visiting the United States, investigates passport and visa fraud, and conducts personnel security investigations. Operating from a global platform in 31 U.S. cities and more than 160 foreign countries, DS ensures that America can conduct diplomacy safely and securely. DS plays a vital role in protecting 275 U.S. diplomatic missions and their personnel overseas, securing critical information systems, investigating passport and visa fraud, and fighting the war on terror.
