Anne Keast-Butler Director GCHQ

“Our mission is simple: we help to keep the country safe, in the real world and online. We focus on communications: how to access, analyse and – occasionally – disrupt the communications of the UK’s adversaries; and on the nation’s cyber security. We work with the Secret Intelligence Service (MI6), MI5, policing, Defence and a myriad of partners overseas, and in the private sector and academia.

The people at GCHQ come from diverse backgrounds and bring their unique skills, but all share a passion to make a difference for their country. This is as true today as it was when GCHQ was founded over a century ago – it’s been at the heart of Britain’s intelligence and security community ever since.

What’s changed today is that technology is now central to our way of life. It influences everything from how we relate to one another, to how states compete in cyberspace. As technology continues to evolve, we’re pioneering a new kind of security for our increasingly complex and interconnected world. GCHQ’s role is more vital than ever”.


Situated on the cliffs of North Cornwall, our Bude site plays a critical part in GCHQ’s mission; collecting the essential data that underpins GCHQ’s operations.

Teams at GCHQ Bude engage in the full breadth of GCHQ’s operational work, but with a key focus on maintaining and managing the collection of data, ensuring it is optimised to respond to real-world events and changes in the telecommunications environment – all vital parts of our mission.


Our brilliant people use cutting-edge technology, technical ingenuity and wide-ranging partnerships to identify, analyse and disrupt threats to the UK.  Our priorities are set by the UK’s National Security Strategy and the decisions of the National Security Council, chaired by the Prime Minister, as well as the Joint Intelligence Committee. We always strive to stay one step ahead of those who are looking to cause our nation and its people harm. Our focus changes as the global threats evolve. We are part of the national response to the Covid-19 pandemic; protecting the NHS, supporting the Government’s development of data science and improving our nation’s economic resilience. We are also tackling a shifting serious crime threat that is looking to exploit the crisis. Our role in keeping the UK digital homeland safe and prosperous is more crucial than ever.
