Investigate unexpected behaviour. And if you cannot adequately control the risks, do not release the system.”</p><h2 id="uk-government-to-use-ai-to-defend">UK government to use AI to defend</h2><p>The AI minister also revealed that the UK government is planning to use advanced AI to counter the threats posed by AI, which will build upon two pilot programs that have helped spot and patch over 1,000 vulnerabilities across government systems.</p><p>In addition, frontier AI systems are undergoing “rigorous evaluations” by the UK’s AI Security Institute (AISI), in order to “identify risks early” and “test robust safeguards to help keep people safe.”</p><p>However, there have been some roadblocks in AISI’s ability to test some of the latest models. In September 2026, US President Donald Trump asked OpenAI and Anthropic to not share their latest models with UK testers until US labs had conducted their own testing.</p><p>Narayan said that the UK government has since worked with the White House, “to retain access for Britain's AISI to the most powerful AI models before they are released" (via <a href="https://www.bbc.co.uk/news/articles/cr78pe09y05xo" target="_blank"><em>BBC</em></a>).</p><p>AI protections are also likely to be introduced as part of the Cyber Security and Resilience bill, Narayan said, with a particular focus on regulations surrounding the reporting and disclosure of AI incidents.</p><p>“It's promising to see the Government taking frontier AI cyber defences seriously,” said Richard Wainwright, Field CTO, EMEA at Okta.</p><p>“As AI agents become more autonomous, safety must be built into the infrastructure UK businesses and government rely on. Everyone wants a 'big red button' to turn off rogue AI agents. The industry is increasingly talking about AI 'kill switches' to help protect critical infrastructure, and I hope they are considered as part of the Cyber Security and Resilience Bill regime.”</p><h2 id="why-does-ai-need-more-regulation">Why does AI need more regulation?</h2><p>In 2026 so far, there have been multiple incidents of frontier AI agents escaping testing environments and breaking into the networks of other companies.</p><p><a href="https://www.reuters.com/legal/litigation/openai-alerts-more-than-100-groups-about-rogue-ai-agent-activity-2026-10-01/" target="_blank">OpenAI has notified more than 100 organizations</a> about unauthorized activity tied to the company’s AI agents, including the <a href="https://www.techradar.com/pro/security/openai-reveals-more-on-hugging-face-ai-hack-incident-and-its-pretty-disturbing-stuff-ai-agents-organized-into-a-swarm-considered-the-risks-of-attack-and-did-whatever-it-took-to-achieve-its-goal" target="_blank">Hugging Face attack</a>.

Slowing down AI development would mean handing the AI development lead to China and potentially compromising US national security.</p><p>The US midterm elections are already <a href="https://www.techradar.com/pro/superpacs-are-funneling-millions-of-dollars-into-pro-ai-candidates-with-trump-saying-communities-that-reject-data-centers-will-end-up-backwards-and-poor" target="_blank">fraught with debate over AI development</a>, especially when it comes to the topic of the thousands of AI data centers that are being proposed across the US.</p> </article> ]]>
