National Security Agency
The National Security Agency (NSA) is a world leader in Signals Intelligence. We carry out some of the nation’s most important and sensitive intelligence activities to secure information superiority for America and its allies.
We have two primary missions. Our Information Assurance mission is the defense: it protects U.S. information by preventing foreign adversaries from gaining access to our information systems. Our Signals Intelligence mission is the offense: collecting foreign signals and producing intelligence to give U.S. policy makers and warfighters the decision advantage. NSA also enables network warfare operations to defeat terrorists and their organizations at home and abroad, consistent with U.S. laws and the protection of privacy and civil liberties.
At the nation’s top cryptologic organization, we employ the best and the brightest, who use their intelligence to solve some of the nation’s most difficult challenges. We are also the largest employer of mathematicians in the country, as well as one of the most important centers of foreign language analysis and research.
