The Best of Microsoft Sentinel Now in Microsoft Defender
Microsoft just took a big leap in security operations. The powerful SIEM capabilities of Microsoft Sentinel are now fully integrated into the Microsoft Defender portal. This means a unified, streamlined security experience for analysts and security teams everywhere.
What’s New: Unified Security Operations Experience
Over the past year, Microsoft has been combining threat protection tools into one platform. Now, the advanced SIEM features from Microsoft Sentinel are accessible directly within Defender. This integration supports multi-tenant and multi-workspace environments, allowing security teams to collaborate and manage incidents across various Sentinel tenants from a single queue.
“The Defender portal is a game-changer. Our team is faster, more focused, and finally working in one place.” — Security Operations Lead, Global Financial Services
This unified experience means less context switching and faster incident response in today’s fast-moving threat landscape.
Major Updates You Should Know
Advanced Hunting Enhancements
Security analysts can now run unified queries across Microsoft Sentinel and Defender data. The Security Copilot assists with KQL query generation, making threat hunting smoother and faster.
Native Case Management
Defender now supports native case workflows, including custom statuses, task assignments, due dates, and multi-incident linking — all while preserving security context.
SOC Optimization Tools
Get tailored recommendations to reduce costs, close data gaps, and improve coverage. These tools help maximize your security ROI and strengthen your overall posture.
Expanded Threat Intelligence
Bulk import indicators, visualize data better, and map threats to MITRE ATT&CK. This enriches investigations with deeper attacker context and visibility.
Embedded Security Copilot
The GenAI-powered Security Copilot is built right into the experience. It summarizes incidents, analyzes scripts, and generates reports to speed up response times and reduce analyst fatigue.
“AI-driven insights reduce false positives by 85% and boost alert correlation speed by 50%.” — Microsoft internal research
Seamless Onboarding and Future Innovations
Connecting your Microsoft Sentinel workspace to Defender is quick and non-disruptive. Your data stays intact, and you can still use the classic Azure experience while unlocking Defender’s full power. Going forward, all new features will be delivered exclusively through the Defender portal.
Why It Matters
This integration empowers security teams to work smarter, detect threats faster, and respond instantly—all in one place. If you want to transform your SecOps, now is the time to get started.
