NSA is at the forefront of U.S. government cryptology, integrating signals intelligence (SIGINT) and cybersecurity to enhance national and allied advantages. Our mission encompasses computer network operations aimed at securing critical insights and services, ensuring decisive advantages for the nation and our allies. NSA's cybersecurity initiatives are pivotal in safeguarding U.S. national security systems, particularly within the Defense Industrial Base and enhancing the security of U.S. weaponry. We are committed to advancing cybersecurity through education, research, and career development. Through foreign signals intelligence (SIGINT), NSA delivers crucial intelligence to U.S. policymakers and military forces. This intelligence, derived from electronic signals and systems used by foreign entities, provides essential insights into the capabilities, actions, and intentions of adversaries worldwide. It supports our efforts to defend the nation, save lives, and advance U.S. objectives and alliances globally.
