U.S. National Security Agency

The U.S. National Security Agency (NSA) is a government agency responsible for collecting and analyzing information to protect national security. It primarily focuses on signals intelligence, which involves intercepting and interpreting communications such as phone calls, emails, and other digital transmissions. The NSA plays a crucial role in safeguarding the country from foreign threats, including terrorism and cyberattacks. It also works to ensure the security of U.S. government communications. While its work is vital for national defense, it has faced scrutiny regarding privacy concerns and the balance between security and civil liberties.
