The head of GCHQ, Anne Keast-Butler, has described artificial intelligence as an 'unstoppable force' that the United Kingdom must harness for good, particularly as the technology becomes increasingly autonomous. Delivering the inaugural GCHQ annual lecture at Bletchley Park on Wednesday, she outlined the agency's recent development of a blueprint for a new national cyber defence capability that integrates cutting-edge agentic AI.
New cyber defence blueprint
Speaking at the historic site where GCHQ's predecessor operated during World War II, Ms Keast-Butler said: 'In the past few months, GCHQ has developed the blueprint for a new national cyber defence capability that will hardwire cutting-edge agentic AI into machine speed cyber defence.' She emphasised that the agency is drawing on decades of machine learning expertise to reimagine cybersecurity while embedding frontier AI deeper into its operations responsibly and ethically.
'AI is an unstoppable force with great opportunity. But it's also a force with risks,' she warned. '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.'
Call for collective action
The GCHQ director urged the technology industry and national security professionals to 'anticipate and drive advancements, together, at the speed of the frontier'. She also called on the public to take action 'from boardrooms to living rooms' to bolster cybersecurity. 'The AI revolution is now fully upon us – with ever faster pace of model releases, increasingly sophisticated agents, and greater system autonomy – transforming the world with both promise and peril,' she said.
Ms Keast-Butler stressed that the ground beneath our feet is shifting fast, making cybersecurity more important than ever. 'That message may sound familiar – the National Cyber Security Centre is 10-years-old, after all – but I'm now saying it with utmost urgency. Cybersecurity is a critical priority for all businesses. Our experts are producing unprecedented levels of advice and guidance, but we need businesses to take immediate action. Not just to protect livelihoods and customers, but for the front line defence of our nation and our economy.'
Threats from Russia and China
The spy chief also warned that Russia is 'relentlessly' targeting critical infrastructure, democratic processes, supply chains and public trust in the UK and Europe. She set out how Russia is increasing its daily hybrid activity against countries including Britain, and urged the public and businesses to make cybersecurity '10 times more urgent'.
GCHQ is 'disrupting Russia's efforts to smuggle western tech, fending off cyber attacks, and countering reckless sabotage and assassination attempts', she said, adding that 'as we remain steadfast in our support for Ukraine, Putin is going backwards on the battlefield'. The speed of technological advancements means there is a 'narrowing window for the UK and allies to stay ahead', she warned.
Regarding China, Ms Keast-Butler noted that it 'is now a science and tech superpower, with sophisticated capabilities across their intelligence, cyber and military agencies'.
Previous warnings
Earlier this year, Dr Richard Horne, head of the National Cyber Security Centre (which is part of GCHQ), warned that most nationally significant cyber attacks on Britain were carried out by hostile states including China, Iran and Russia. He said the body dealt with around four such attacks each week, and warned businesses to be prepared to protect themselves without relying on paying ransoms, because the UK could be targeted 'at scale' if it became involved in an international conflict.
