In the United States, the Diplomatic Security Service (DSS) provides protective security details for the U.S. Secretary of State, the U.S. Ambassador to the United Nations, and certain visiting foreign dignitaries. Additionally, DSS assists foreign diplomatic missions in the United States on all security-related matters.

Overseas, regional security officers advise ambassadors or chiefs of mission and develop security programs to protect embassy and consulate personnel.
