Graylog
- +Noticeably easier to stand up and operate than Elastic for log management
- +Open-source edition is genuinely usable rather than a crippled trial
- +Strong search and alerting for the operational logging use case
- −Security-specific content is thinner than dedicated SIEM platforms
- −Enterprise edition returns to volume-based pricing
Best for Teams wanting solid self-hosted log management with a path toward SIEM
Watch out Check which security features require Enterprise before assuming the free tier suffices
Microsoft Sentinel
- +No infrastructure to size, patch or scale — fully managed by Microsoft
- +Excellent native coverage of Entra ID, Microsoft 365 and Azure workloads
- +Large library of prebuilt analytics rules and workbooks
- −Azure only — data residency is limited to available Azure regions
- −Per-gigabyte pricing directly penalises comprehensive log collection
Best for Azure-committed organisations without residency constraints
Watch out Per-GB cost at scale surprises most teams; run a realistic volume forecast first
