BT announced an expanded partnership with Microsoft on October 14, 2026, to strengthen cyber defenses for UK organizations against AI-powered threats. The collaboration combines Microsoft security technology with BT's security operations and network insight. BT is launching Security Operations Centre-as-a-Service for Microsoft Sentinel, a UK-managed service integrating Sentinel with BT's threat intelligence and security expertise, reflecting a deepening strategic relationship across AI, security, and cloud services.

BT's managed Sentinel service highlights the growing trend of telecom providers packaging Microsoft security solutions with managed services, a competitive dynamic that affects Tech Data's managed security services positioning in EMEA. While BT operates at carrier scale, the partnership validates the market opportunity for Microsoft Sentinel-based MSSPs in our channel. This underscores the importance of our Security Services practice development and technical enablement for partners building Sentinel-based SOC offerings.
