Microsoft Sentinel review and pricing

Cloud-native SIEM for Microsoft-anchored organizations.

By Microsoft Corporation · Founded 2019 · Redmond, WA · public

Microsoft Sentinel is the cloud-native SIEM tightly integrated with the Microsoft security stack, Defender XDR, Microsoft 365, Azure AD/Entra, and Azure security services. The product's defining advantage: free ingestion tiers for Microsoft data sources, dramatically reducing total cost for organizations already on Microsoft 365 + Azure. Trade-offs: best-fit narrowed to Microsoft-anchored orgs, KQL learning curve, less customization than Splunk SPL.

Organizations already on Microsoft 365 + Azure (especially Defender XDR) wanting native SIEM at significantly lower TCO than Splunk.

Worst for

Vendor Trust is scored independently of product quality. A great product from an unfair vendor still earns a low trust score.
