Microsoft Defender + Sentinel

Microsoft's unified security portfolio, anchored by Microsoft Sentinel and Defender for Endpoint, is the most widely deployed enterprise security platform worldwide. The 2026 convergence into a single Microsoft Defender portal manages identity, email, endpoint, cloud, and SaaS threats, all powered by Security Copilot AI. Microsoft was named a Leader in the 2026 Gartner Magic Quadrant for Endpoint Protection Platforms for the seventh consecutive year. Sentinel processes over 25 petabytes of security data daily, and its AI-powered playbook generator reduces authoring time by an estimated 65%. The average enterprise consolidating to Microsoft's platform reduces total tooling cost by 60%. Sentinel's AI migration tooling maps rules from Splunk or QRadar to KQL, streamlining transitions with 200+ built-in connectors.
