BT has deepened its partnership with Microsoft to help UK organisations strengthen cyber defences against AI-powered threats. The expanded collaboration covers public and private sector organisations and combines Microsoft security technology with BT’s scale, security operations and network insight.
AI is accelerating the speed, scale and sophistication of cyber-attacks. The Microsoft Digital Defense Report 2026 describes AI as changing cybersecurity conditions and compressing attack timelines, with the average time from discovery to weaponisation of security vulnerabilities now well below 24 hours. UK organisations need to adopt more pre-emptive and predictive cyber defence solutions.
BT is launching Security Operations Centre-as-a-Service (SOCaaS) for Microsoft Sentinel, a UK-managed service that combines Sentinel with BT’s security operations expertise, threat intelligence and experience. It builds on BT’s established work as a managed security provider for Sentinel and reflects the wider relationship between BT and Microsoft across AI, security and cloud services. The offering is packaged as a single managed service.
BT reported that it blocks around four million attempted cyber-attacks each day and that it protects more businesses than any other network. The company said its service combines Sentinel, managed operations, threat intelligence and UK cyber expertise in one offering. It follows a recent launch of cyber tools and support for small businesses, and BT’s wider cyber portfolio combines managed security operations, continuous threat exposure management and AI-enabled capabilities.
Jon James, CEO, BT Business, said: “AI is transforming the cyber threat landscape at unprecedented speed, and our customers need protection that stays one step ahead. By extending our partnership with Microsoft, we’re combining cutting-edge security technology with BT’s cyber expertise and threat intelligence to deliver stronger, more proactive protection. It’s the latest example of how we’re helping organisations build resilience and defend against the next generation of AI-powered threats.”
Darren Hardman, CEO, Microsoft UK & Ireland, said: “AI is increasing the speed, scale and sophistication of cyber threats. By combining Microsoft Sentinel with BT’s managed security expertise and UK cyber operations, we can help organisations simplify security, strengthen resilience and respond with greater confidence.” BT describes the service as a way for customers to cut complexity, control costs and improve detection, response and resilience as threats continue to evolve.
