Computer Network Operations

We hack the computers of terrorists
to disrupt their plans.

Computer Network Operations


Here at GCHQ, we have a clear purpose – we want to help protect the UK. Everyone who works here, works towards that goal. And we always do it together, supporting each other every step of the way. We’re proud to collaborate, and even prouder of our purpose.

At the heart of this, sits our Computer Network Operations team whose job it is to protect the country from cyber-attacks and ever evolving threats. It’s incredibly interesting work where, under strict legal safeguards, they put their skills to use doing things that simply aren’t possible elsewhere. From legally hacking the computers of terrorists, to gathering intelligence, and developing software that disrupts criminal plans, their creative thinking and collaborative approach make a huge difference every day.
