An intelligence agency is a government organization responsible for gathering, analyzing, and disseminating information related to national security. These agencies work to protect a country from threats such as terrorism, espionage, and cyberattacks. They collect data through various means, including surveillance, human intelligence, and open-source information. Intelligence agencies often collaborate with other countries and organizations to share information and enhance security efforts. Notable examples include the Central Intelligence Agency (CIA) in the United States and the MI6 in the United Kingdom. Their work is crucial for informing government decisions and ensuring the safety of citizens.
