Working with other government departments
Intelligence and Security Agencies
GCHQ is one of the three UK Intelligence and Security Agencies.
Where we deal with communications, the other agencies are concerned with collecting human intelligence. MI5 focuses its efforts within the UK, while the Secret Intelligence Service (MI6) concentrates abroad.
All three agencies work together to protect the UK against covertly organised threats to national security, and to help inform Government policy and the UK's response to world events.
Public sector partnerships
In our role as the National Technical Authority for Information Assurance, we have vital relationships with other government departments and agencies.
Our primary work is with the Ministry of Defence, the Foreign and Commonwealth Office, and numerous law enforcement agencies, helping them to protect their own systems and to secure their information. For example, we provide technical guidance to the Centre for the Protection of National Infrastructure (CPNI), the Government authority which provides protective security advice to business and organisations across the national infrastructure.
Countering the growing threat from cyber requires a coordinated response across multiple departments. GCHQ worked with the Department for Business, Innovation and Skills (BIS), Cabinet Office and CPNI to produce the '10 Steps to Cyber Security', a guide for board members of companies to ensure their company is addressing the cyber risk appropriately.
We also work with the Office of Cyber Security and Information Assurance (OCSIA) in Cabinet Office, who provide the strategic direction on cyber security.
