sigma-rule-helper

A small helper for reviewing Sigma rules with narrow, explainable checks.

Detection-rule review active Case study updated October 2026
PythonSigmaReview checks

Keeps rule review local and the checks easy to inspect.

Focus

This project applies small review checks to Sigma rules. The useful output is something a reviewer can investigate, rather than an opaque score or a claim that the rule is correct.

Evidence

The repository contains the current checks, sample rules and tests. It is intentionally a helper for a human review workflow.

Boundaries

It does not validate a rule against a production telemetry pipeline or replace testing detections with representative events.
