Microsoft named a Leader in the 2025 Gartner® Magic Quadrant™ for SIEM

We’re honored to share that Microsoft has again been recognized as a Leader in the 2025 Gartner® Magic Quadrant™ for Security Information and Event Management (SIEM).¹ We believe this recognition reinforces Microsoft Sentinel‘s position as an industry-leading, cloud and AI-powered SIEM—designed to solve SOC challenges head-on and streamline modern security operations.

Strengthening cyber defense in the age of agentic AI with Microsoft Sentinel

Microsoft Sentinel has now evolved beyond a cloud-native SIEM into a unified, AI-powered security platform, connecting analytics and context across ecosystems at scale. With a centralized, purpose-built security data lake and graph capabilities, organizations gain deeper insights and richer context for more effective cyberthreat detection and investigation. The Model Context Protocol (MCP) server and agentic tools make data agent-ready, paving the way for seamless integration with autonomous security agents and unlocking new possibilities for proactive defense.

We realized that we needed to uplift our capability in the security operations center. We wanted a platform that could help us face the challenges of offensive use of AI so we could defend at machine speed.

—David Boda, Chief Security and Resilience Officer, Nationwide

Optimizing costs and coverage

Now generally available, the Microsoft Sentinel data lake serves as the foundation for modern, AI-powered security operations. Purpose-built for security, it features a cloud-native architecture that centralizes all security data from more than 350 sources across platforms and clouds. The Microsoft Sentinel data lake simplifies data management, eliminating silos, and enables cost-effective long-term retention, empowering organizations to maintain strong security postures while optimizing budget. By unifying historical and real-time security data, the data lake helps AI agents and automation perform advanced analytics, detect anomalies, and execute autonomous cyberthreat responses with precision and speed.

To further help organizations optimize their security operations, Microsoft Sentinel has native features like:

• SOC optimization helps security teams improve coverage, reduce costs, and streamline operations by providing AI-powered recommendations on data usage, cyberthreat detection gaps, and analytics efficiency. These insights empower defenders to make smarter decisions and maximize return on investment.
• New cost management features in preview help customers with cost predictability, billing transparency, and operational efficiency.

Accelerating the SOC with advanced analytics and AI

Microsoft Sentinel is transforming security operations with advanced analytics, agentic AI, and MCP server. Microsoft Sentinel data lake centralizes security data from hundreds of sources, enabling real-time detection, contextual analysis, and autonomous response. The integration of agentic AI and Microsoft Security Copilot allows defenders to automate investigations, correlate complex signals, and respond to cyberthreats at machine speed. The MCP server further enhances these capabilities by making security data agent-ready. Support for tools like Kusto Query Language (KQL) queries, Spark notebooks, and machine learning models within the Microsoft Sentinel data lake empowers agentic systems to continuously learn, adapt, and act on emerging cyberthreats, driving smarter, faster, and more contextual security operations across the SOC. This AI-powered approach reduces alert fatigue and accelerates decision-making, strengthening security posture across the SOC.

Together, these capabilities empower SOC teams to operate at the speed of AI, reduce noise, and focus on high-impact investigations, driving clarity, efficiency, and resilience across the security lifecycle.

Empowering defenders with industry-leading SIEM

Microsoft Sentinel enhances security operations by unifying SIEM, security orchestration, automation, and response (SOAR), user and entity behavior analytics (UEBA), and threat intelligence into a single, integrated experience. With full integration into the Microsoft Defender portal, Microsoft Sentinel delivers a consolidated view for detection, investigation, and response across endpoints, identities, cloud, and network—streamlining workflows and enhancing efficiency for SOC teams.

• Advanced correlation algorithms combine behavioral analytics, machine learning, and threat intelligence to connect events and deliver comprehensive security insights.
• Custom rules and MITRE ATT&CK® mapping allow defenders to tailor detection strategies for their specific needs.
• Built-in orchestration and automation capabilities reduce manual effort, accelerate incident response, and free analysts to focus on high-value tasks.
• UEBA powered by AI provide deep behavioral insights to detect anomalies and insider threats.
• Integrated threat intelligence enriches investigations with real-time insights, enabling faster detection, deeper context, and more accurate response across the SOC.
• Embedded AI and machine learning accelerate threat detection, reduce false positives, and enable advanced hunting and automated investigations—helping SOC teams respond faster and with precision.

Microsoft Sentinel has comprehensive machine learning threat analytics models that allow us to hunt and detect any security threat, no matter how sophisticated or hidden they are. Microsoft Sentinel has intelligent security event management features which help us to accurately investigate security threats to understand the origin, making it easy to identify the most appropriate way to handle them.
