What We Do


  • Saves lives
  • Defends vital networks
  • Advances U.S. goals and alliances
  • Protects privacy rights
  • Is a unique asset

We are well-positioned to carry out our missions because NSA is both a member of the Defense Department and an Intelligence Community agency.

U.S. leaders, policymakers, war fighters, law enforcement agencies and our Intelligence Community partners face some of the gravest national security challenges in U.S. history.

To overcome the very real threats to our country, national decision makers:

  • Need to know what our adversaries are doing and what their capabilities are so they can make decisions and plans, and execute policies and operations;
  • Need to be able to communicate and exchange information securely, so that our adversaries can't undermine our plans;
  • Must be able to outmaneuver those who would do us harm in cyberspace.

NSA is the world leader in cryptology - the art and science of making and breaking codes.

It is this expertise- from our people and technology- that allows us to accomplish the goals of discovering adversaries' secrets, protecting U.S. secrets, and outmaneuvering our adversaries in cyberspace while at the same time protecting the privacy rights of the American people.
