About:
sigma-cli is the official command-line interface for the pySigma library, enabling security analysts to convert Sigma detection rules into various target formats. It provides a unified workflow for translating threat detection logic into vendor-specific queries for SIEMs like Splunk, Elasticsearch, and Microsoft Sentinel. This tool streamlines threat hunting and detection engineering by bridging the gap between open-source Sigma rules and proprietary security platforms.
Key Features:
  • Converts Sigma rules into multiple query languages (SPL, KQL, etc.)
  • Supports a wide range of backends for commercial and open-source SIEMs
  • Extensible via plugins for pipelines, backends, and outputs
  • Integrates with CI/CD pipelines for automated rule management
Use Cases:
  • Converting Sigma rules for deployment into a specific SIEM environment
  • Validating and testing Sigma rule conversions during development
  • Automating detection rule updates in a DevSecOps workflow
Alternatives:
  • sigmac – The legacy, standalone converter; sigma-cli is the modern, plugin-based successor built on pySigma.
