Google Security Operations vs Microsoft Sentinel
Google Security Operations totals 6.83 and Microsoft Sentinel totals 7.81 on the 10 point detection-as-code rubric (sources read 2026-11-03 and 2026-11-04). Microsoft Sentinel leads by 0.98 points. The pair turns on testing: Google Security Operations documents it in full, and Microsoft Sentinel documents it only in part, or as a vendor claim. Neither documents field drift alerts tied to rules.
The difference that decides this pair
The largest weighted gap on the rubric is coverage analytics: Microsoft Sentinel scores 8.0 against 4.0 for Google Security Operations, which is 0.48 of the 10 point total.
The pair splits on testing: Google Security Operations tests a rule over a time range, retrohunts against historical data and offers event simulation (pre-GA), and Microsoft Sentinel documents manual rerun of analytics rules and results simulation, with no unit test step. docs.cloud.google.com read 2026-11-03 learn.microsoft.com read 2026-11-03

Verdict by buyer type
Which of the two fits each kind of team.
| Buyer | Verdict |
|---|---|
| Microsoft Sentinel estate | Microsoft Sentinel is the better fit: it runs the estate natively and deploys rules from GitHub or Azure DevOps; Google Security Operations documents no Sentinel path. |
| Google SecOps estate | Google Security Operations is the better fit: it runs the estate natively, with YARA-L rules, a Rules API and a Content Manager CLI; Microsoft Sentinel documents no Google SecOps path. |
| a team starting from scratch with Sigma | Neither Google Security Operations nor Microsoft Sentinel documents a path for this buyer, so it does not separate them. |
