GCHQ has drawn up plans for a national AI cyber defence system, believed to be the first of its kind globally. The system aims to be operational within five years, using AI agents to detect and flag threats to critical national infrastructure, airlines, telecoms firms and other major companies. The initiative seeks to make major hacks, such as the breach that targeted Jaguar Land Rover, significantly less likely.
The plans were revealed by GCHQ director Anne Keast-Butler during the spy agency’s inaugural annual lecture at Bletchley Park on Wednesday. She described AI as an “unstoppable force” that the UK must harness for good as the technology becomes increasingly autonomous. Keast-Butler stated that GCHQ has developed a blueprint for a new national cyber defence capability that will integrate cutting-edge agentic AI into machine-speed cyber defence.
Keast-Butler urged the technology industry and national security professionals to “anticipate and drive advancements, together, at the speed of the frontier”. She called on the public to take action “from boardrooms to living rooms” to enhance cyber security, emphasising that the AI revolution is transforming the world with both promise and peril.
The GCHQ director also warned that Russia is “relentlessly” targeting critical infrastructure, democratic processes, supply chains and public trust in the UK and Europe. She noted that Russia is increasing its daily hybrid activity against countries including Britain, and urged the public and businesses to make cyber security “10 times more urgent”. New intelligence indicates that nearly 500,000 Russian soldiers have been killed in the conflict in Ukraine.
Keast-Butler highlighted that China is now a science and tech superpower with sophisticated capabilities across intelligence, cyber and military agencies. Earlier this year, Dr Richard Horne, head of the National Cyber Security Centre, warned that most nationally significant cyber attacks on Britain were carried out by hostile states, including China, Iran and Russia, with the body dealing with around four such attacks each week.
