GCHQ has introduced a blueprint for a national cyber defence capability amid increased threats from adversaries.

Anne Keast-Butler, director of GCHQ, the UK’s intelligence, cyber and security agency, has delivered the first annual lecture at Bletchley Park. Her speech marked the 80th anniversary of the UKUSA intelligence agreement, which later evolved into the Five Eyes security alliance between the UK, US, Australia, Canada and New Zealand.

“It’s rare for any head of an intelligence agency to speak in public, but I’m doing so to you today because we are at a moment of consequence – where the actions we take and the partnerships we build are ever more critical given the threats we face,” said Keast-Butler at the start of her lecture.

She emphasised the importance of international partnerships for increasing resilience and harnessing technology for good amid a “narrowing window for the UK and allies to stay ahead”.

She warned about the increasingly brazen behaviour from adversaries with “Russia scaling up its daily hybrid activity against the UK and Europe” and that we have now entered a “new era of radical uncertainty, contested geopolitics and rapidly changing technology”.

The UK has always prided itself on being a global leader in science and tech, but there’s a narrowing window for the UK and its allies to stay ahead, according to Keast-Butler.

She particularly spoke of the increasing threat of cyber security in today’s AI world and the urgency to take action. Cyber security must now become “10 times more urgent” and requires a tightening of digital defences “from boardrooms to living rooms”.

GCHQ is itself taking action with the development of a “blueprint for a new national cyber defence capability [that] will hardwire cutting-edge agentic AI into machine speed cyber defence”.

The system, which is hoped to be running within five years, will use AI agents to detect and flag threats to critical national infrastructure, airlines, telecoms firms and other major companies. 

GCHQ is also embedding frontier AI into its operations to “enhance algorithms, translate foreign languages and find needles in haystacks faster than ever before”.

“As AI gains increased autonomy, we all have an intergenerational duty to harness and secure it for good; to protect our national security, our economy and our way of life,” said Keast-Butler.
