Detection as Code

Microsoft Sentinel vs Panther

Microsoft Sentinel totals 7.81 and Panther totals 6.31 on the 10 point detection-as-code rubric (sources read 2026-11-03 and 2026-11-04). Microsoft Sentinel leads by 1.50 points. The pair turns on rule languages: Panther documents it in full, and Microsoft Sentinel documents it only in part, or as a vendor claim.

The difference that decides this pair

The largest weighted gap on the rubric is rule health: Microsoft Sentinel scores 9.0 against 3.5 for Panther, which is 0.99 of the 10 point total.

Microsoft Sentinel runs KQL analytics rules and documents no Sigma path; Panther, by contrast, writes detections in Python and converts Sigma rules with sigma-cli. docs.panther.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.

BuyerVerdict
Microsoft Sentinel estateMicrosoft Sentinel is the better fit: it runs the estate natively and deploys rules from GitHub or Azure DevOps; Panther documents no Sentinel path.
a team starting from scratch with SigmaPanther is the better fit: it converts Sigma with sigma-cli into Python or Simple detections and tests them in CI; Microsoft Sentinel documents KQL and no Sigma path.
Elastic estateNeither Microsoft Sentinel nor Panther documents a path for this buyer, so it does not separate them.

When to pick each

Microsoft Sentinel: Pick Microsoft Sentinel when rule health is the deciding need: it logs run status and failure reasons in the SentinelHealth table and exposes auto-disabled scheduled rules by query. It also leads on versioning and lifecycle.

Panther: Pick Panther when testing is the deciding need: it runs per-detection unit tests with panther_analysis_tool test and previews a rule on stored logs with Data Replay (Beta). It also leads on rule languages.

Profiles: Microsoft Sentinel, Panther. Alternatives: to Microsoft Sentinel, to Panther.
