Detection as Code

Elastic Security vs Microsoft Sentinel

Elastic Security totals 7.60 and Microsoft Sentinel totals 7.81 on the 10 point detection-as-code rubric (sources read 2026-11-03 and 2026-11-04). The totals sit within 0.25, too close for the evidence to separate them. The pair turns on coverage analytics: Microsoft Sentinel documents it in full, and Elastic Security documents it only in part, or as a vendor claim.

The difference that decides this pair

The largest weighted gap on the rubric is coverage analytics: Microsoft Sentinel scores 8.0 against 5.0 for Elastic Security, which is 0.36 of the 10 point total.

For coverage analytics, the Microsoft Sentinel MITRE page shows a coverage matrix of active rules and simulated coverage from rules not yet configured, whereas Elastic Security filters rules by ATT&CK tactic and technique but documents no in-product coverage matrix or gap view. learn.microsoft.com read 2026-11-04 elastic.co read 2026-11-04

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; Elastic Security documents no Sentinel path.
Elastic estateElastic Security is the better fit: it runs the estate natively and ships a detection_rules CLI for rules as TOML files; Microsoft Sentinel documents no Elastic path.
a team starting from scratch with SigmaNeither Elastic Security nor Microsoft Sentinel documents a path for this buyer, so it does not separate them.

When to pick each

Elastic Security: Pick Elastic Security when testing is the deciding need: it ships Python unit tests for rules in the detection-rules repo and can run a rule manually over a past time range. It also leads on content library size.

Microsoft Sentinel: Pick Microsoft Sentinel when CI and deployment matters more to you than testing, where Elastic Security documents more: it connects a workspace to GitHub or Azure DevOps and deploys changed rules through a generated workflow.

Profiles: Elastic Security, Microsoft Sentinel. Alternatives: to Elastic Security, to Microsoft Sentinel.
