Microsoft Sentinel

Microsoft Sentinel is a cloud-native SIEM and SOAR (Security Orchestration, Automation, and Response) platform built on Azure — providing security analytics, threat detection, and automated response with consumption-based pricing.

What Makes Microsoft Sentinel Stand Out

Cloud-native with no infrastructure to manage. Microsoft ecosystem integration makes it natural for Azure/Microsoft 365 organizations

AI-powered threat intelligence from Microsoft's global security research

Pricing and Plans

Microsoft Sentinel offers a free tier that provides meaningful value for individuals and small teams, with paid plans unlocking additional capabilities as needs grow.

Who Should Use Microsoft Sentinel

Microsoft Sentinel is best for teams and individuals who need siem software capabilities and where cloud-native with no infrastructure to manage. It may not be the right fit when cost can escalate significantly with high data volumes.

Verdict

Microsoft Sentinel delivers on its core promise as a siem software tool. Microsoft Sentinel is a cloud-native SIEM and SOAR (Security Orchestration, Automation, and Response... For teams evaluating siem software options, Microsoft Sentinel is worth considering based on its specific strengths and how they align with your requirements.

Playbook Automation

Sentinel's SOAR playbooks (built on Azure Logic Apps) automate response actions: isolating compromised endpoints, blocking malicious IPs, notifying stakeholders, and creating helpdesk tickets — all triggered automatically by specific alert types without waiting for analyst response.

Workbooks and Dashboards

Sentinel's workbooks provide customizable visualizations of security data: threat geography maps, authentication anomaly charts, and compliance status dashboards. Pre-built workbooks cover common security monitoring scenarios; customization enables organization-specific security metrics.

Third-Party Data Connectors

Sentinel's connector library includes 300+ out-of-box connectors for security products: Palo Alto, Cisco, CrowdStrike, AWS, and many others — enabling organizations to centralize security signals from their full security stack, not just Microsoft products.

Threat Intelligence Integration

Sentinel ingests threat intelligence from Microsoft Threat Intelligence, commercial TI feeds, and custom indicators — enabling matching observed security events against known malicious infrastructure, attack patterns, and threat actor TTPs.

Overall rating: 4.1 / 5

Microsoft Sentinel is the cloud-native SIEM and SOAR platform built on Microsoft Azure — ingesting security signals from Microsoft products, third-party services, and custom log sources for threat detection, investigation, and automated response.

Built-In AI and Machine Learning

Sentinel's UEBA (User and Entity Behavior Analytics) uses machine learning to establish behavioral baselines for users and entities — detecting anomalies that rule-based detection misses. An employee who suddenly accesses 10x their normal file volume at 3am triggers UEBA anomaly detection without requiring a pre-written detection rule.

Cost Model Advantage

Sentinel's consumption-based pricing charges per GB of log data ingested — organizations control costs by selectively ingesting high-value security logs rather than ingesting everything. Microsoft 365 Defender logs are free to ingest, reducing cost for organizations already in the Microsoft ecosystem.

Sentinel vs. Splunk SIEM

Splunk has more mature threat hunting tools and broader non-Microsoft data source support. Sentinel is the natural choice for Microsoft-heavy organizations: Azure AD, Defender for Endpoint, and Microsoft 365 data integrates natively with minimal configuration.
