BT joins Anthropic’s Project Glasswing to strengthen cyber defences with frontier AI

• BT becomes the first UK company to confirm it has joined Anthropic’s Project Glasswing
• The project helps the world’s critical infrastructure providers secure their systems with frontier AI
• BT announced the news at the UK Government’s ‘AI Adoption Summit’, which aims to accelerate AI usage across the UK economy in a safe and positive way
• Membership will help BT strengthen cyber security for its networks and the country, and enable greater protection against the latest AI threats for BT’s customers

BT has become the first UK company to confirm its membership of Anthropic’s Project Glasswing – giving access to Claude Mythos Preview, Anthropic’s frontier AI model, and strengthening BT’s protection against cyber security threats for its networks and customers.

Project Glasswing brings together critical infrastructure providers to secure data and systems which underpin services that millions of people rely on. It allows trusted organisations to use Anthropic’s safe AI systems to rapidly identify vulnerabilities – and help fix them before criminals can take advantage.

BT’s Chief Executive, Allison Kirkby, announced the news as she opened the UK Government’s ‘AI Adoption Summit’ earlier today, which featured the Chancellor of the Exchequer Rachel Reeves, DSIT Secretary Liz Kendall, Business Secretary Peter Kyle, Cabinet Secretary Antonia Romeo and Minister for AI and Online Safety Kanishka Narayan.

Allison’s speech outlined the critical role of connectivity in ensuring the UK can seize the growth potential of AI, stating that “AI only works at scale when it is underpinned by future-ready networks that are secure, resilient, safe”. She also emphasised BT’s commitment “to working with Government to support the further development and deployment of sovereign British AI capability, so that the UK can be an AI maker and not just a taker”, and to acting as an “enabler of responsible adoption and a responsible adopter ourselves” in AI.

BT’s participation in Project Glasswing reflects its role in securing UK critical national infrastructure, and as one of the UK’s leading providers of security managed services. BT now prevents four million cyber-attacks across its networks every day, underlining the scale of the threat and the importance of staying ahead of it.

Jon James, Chief Executive Officer, BT Business said: “AI is changing cyber security fast, and businesses need trusted partners who can help them stay one step ahead. By joining Project Glasswing, BT will strengthen its own cyber security capability to protect our networks, our customers and the wider UK.”

BT Business already provides AI-powered cybersecurity solutions to customers of all sizes, including new products for small businesses – and recently announced a collaboration with Accenture to develop advanced AI-powered cyber operations, responding to cyber threats at machine speed.
