An NSA Police Career involves the protection of NSA buildings, as well as agency personnel, resources and equipment. NSA Police officers wear uniforms and are licensed to carry firearms.

NSA provides foreign signals intelligence (SIGINT) to our nation's policymakers and military forces. SIGINT plays a vital role in our national security by providing America's leaders with critical information they need to defend our country, save lives, and advance U.S. goals and alliances globally.

NSA has declared that it relies on the FBI to collect information on foreign intelligence activities within the borders of the United States, while confining its own activities within the United States to the embassies and missions of foreign nations.

As a defense agency, NSA operates under the authority of the Department of Defense. As a member of the Intelligence Community, NSA also operates under the Office of the Director of National Intelligence. NSA/CSS activities are subject to strict scrutiny and oversight both from the outside and from within.
