NSA Cybersecurity prevents and eradicates threats to U.S. national security systems, with an initial focus on the Defense Industrial Base (DIB) and the improvement of the nation's weapons' security.

NSA employs a wide variety of cyber professionals to help protect and defend U.S. government IT systems and to help exploit the intelligence of adversaries.

Unlike the CIA and the Defense Intelligence Agency (DIA), both of which specialize primarily in foreign human espionage, the NSA does not publicly conduct human intelligence gathering.

The National Security Agency/Central Security Service (NSA/CSS) leads the U.S. Government in cryptology that encompasses both signals intelligence (SIGINT) insights and cybersecurity products and services and enables computer network operations to gain a decisive advantage for the nation and our allies.
