Intelligence agencies are government organizations responsible for gathering, analyzing, and interpreting information related to national security. They work to protect a country's interests by monitoring potential threats, such as terrorism or espionage, and providing insights to policymakers. Examples of intelligence agencies include the CIA in the United States and MI6 in the United Kingdom. These agencies use various methods to collect information, including surveillance, human intelligence, and cyber operations. Their work is often secretive, as it involves sensitive data that could impact national safety. Intelligence agencies play a crucial role in shaping defense strategies and responding to global events.
