Government Communications Headquarters (GCHQ) is an intelligence and security organisation. A Civil Service Department, we report to the Foreign Secretary and work closely with the UK's other intelligence agencies (commonly known as MI5 and MI6). Our primary customers are the Ministry of Defence, the Foreign and Commonwealth Office and law enforcement authorities, but we also serve a wide range of other Government Departments.
GCHQ has two missions: signals intelligence (Sigint) and Information Assurance.
Our Sigint work protects the vital interests of the nation: we provide information to support Government decision making in the fields of national security, military operations and law enforcement. The intelligence we provide is at the heart of the struggle against terrorism and also contributes to the prevention of serious crime.
Information Assurance helps keep Government communication and information systems safe from hackers and other threats. We also help those responsible for the UK's critical national infrastructure (power, water, communications etc.) keep their networks safe from interference and disruption.
