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.

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.

Our global workforce — composed of about 60% civilians and 40% military members from every branch of the U.S. Armed Forces — is the driving force behind NSA's mission. Bringing diverse individual experiences and perspectives together is a key part of NSA's ability to overcome our greatest challenges.

The NSA, alongside the CIA, maintains a physical presence in many countries across the globe; the CIA/NSA joint Special Collection Service (a highly classified intelligence team) inserts eavesdropping devices in high-value targets (such as presidential palaces or embassies).
