National Security Agency/Central Security Service

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. Throughout the site, NSA/CSS will be referred to collectively as NSA. NSA is part of the U.S. Department of Defense serving as a combat support agency. Supporting our military service members around the world is one of the most important things that we do. NSA analysts, linguists, engineers and other personnel deploy to Afghanistan and other hostile areas to provide actionable SIGINT and cybersecurity support to warfighters on the front lines. We provide intelligence support to military operations through our signals intelligence activities, while our cybersecurity personnel, products and services ensure that military communications and data remain secure, and out of the hands of our adversaries. The Central Security Service (CSS) provides timely and accurate cryptologic support, knowledge, and assistance to the military cryptologic community. Established by presidential directive in 1972, CSS promotes full partnership between the NSA and the cryptologic elements of the Armed Forces, and teams with senior military and civilian leaders to address and act on critical military-related issues in support of national and tactical intelligence objectives. CSS coordinates and develops policy and guidance on the signals intelligence and cybersecurity missions of NSA/CSS to ensure military integration.
