Using strong passwords, updating your software, thinking before you click on suspicious links, and turning on multi-factor authentication are the basics of what we call “cyber hygiene” and will drastically improve your online safety.

The National Security Agency (NSA) 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.

NSA's Center for Cybersecurity Standards supports collaboration with industry to ensure U.S. Government cybersecurity requirements are included in the standards for a more secure future. These standards enable interoperable IT solutions and mitigate security challenges across networks.

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.
