BT and Microsoft launch managed security service for UK organisations
BT has broadened its collaboration with Microsoft to offer UK businesses and public-sector bodies a managed security operations service. The offering uses Microsoft Sentinel and BT's network intelligence to help detect and respond to cyber threats faster. BT says it blocks about four million attempted attacks daily, while Microsoft reports that exploitation of vulnerabilities now often occurs within a day.
BT has widened its existing alliance with Microsoft to introduce a UK-focused managed security operations service. The product, delivered as SOC-as-a-Service, relies on Microsoft Sentinel and BT's visibility into network traffic and security operations.
The launch reflects a threat environment where Microsoft's 2026 Digital Defense Report says exploitation can follow vulnerability discovery in less than a day. BT, meanwhile, reports blocking roughly four million attempted attacks each day. BT Business CEO Jon James and Microsoft UK and Ireland CEO Darren Hardman both linked the service to AI-driven threats and resilience.
UK businesses and public-sector bodies may gain faster threat detection and response, potentially reducing disruption to services and data. Smaller organisations with limited security teams could benefit most from managed expertise, though reliance on a few large providers may raise concentration and cost considerations. Employees, customers, and citizens could feel effects through fewer outages or breaches, but outcomes depend on implementation, transparency, and oversight.
