Microsoft is reimagining cloud-native security operations with a significant update to Microsoft Sentinel—introducing Microsoft Sentinel: Data Lake. This evolution provides a scalable, cost-efficient foundation for security data management, purpose-built for the age of agentic AI and real-time response.

As cyber threats become increasingly advanced and widespread, organizations require solutions that unify data, simplify complexity, and enable faster, smarter action. The new capabilities in Microsoft Sentinel deliver just that: a unified, open, AI-optimized security data platform that helps security operations centers (SOCs) respond quickly with less overhead.

What’s New in Microsoft Sentinel: Data Lake

Unified Security Data Fabric

Microsoft Sentinel now stores data in Microsoft Fabric OneLake—an open, multicloud data lake. It enables security teams to ingest and analyze data from a wide range of sources, including clouds, SaaS apps, endpoints, identity platforms, and more—all in one centralized place.

Agentic AI for Security Automation

Integrated with Microsoft Security Copilot and Fabric’s AI tools, Sentinel now enables intelligent investigation and automated response. It shifts operations from a reactive defense to a proactive, AI-driven orchestration, reducing response times and boosting analyst productivity.

Lower Costs, Greater Flexibility

By eliminating data duplication, Sentinel’s new architecture reduces ingestion and storage costs. Teams can manage both native and federated data without rigid retention structures, giving them better cost transparency and control.

Native Integration Across Microsoft Cloud

Security data from Microsoft Defender, Entra, Intune, and Purview can now be accessed natively—without duplication—streamlining detection and investigation while maintaining context and compliance.
