What is this?
Sigma is a generic, open signature format for describing detection patterns in log events, and this repository is the main collection of over 3000 community-written Sigma detection rules for SIEM systems.
Sigma is a generic, open signature format for describing detection patterns in log events, and this repository is the main collection of over 3000 community-written Sigma detection rules for SIEM systems.Is this a working tool or just a collection of rule files?It is purely a collection of plain-text rule files written in the Sigma format, not an executable program. You need a separate converter to turn these rules into actual queries for your SIEM.

You need a separate converter to turn these rules into actual queries for your SIEM.How do I actually use these rules in my SIEM?Download the latest rule package from the release page, then convert the rules into your SIEM's query language using the official Sigma CLI, the sigconverter.io web GUI, or Detection Studio.

Sigma rules by themselves don't run anywhere; you need Sigma CLI or the pySigma library to translate them into the native query language of your target platform (Splunk, Elastic, etc.).
Yes. Sigma rules by themselves don't run anywhere; you need Sigma CLI or the pySigma library to translate them into the native query language of your target platform (Splunk, Elastic, etc.).Will these rules work directly on my SIEM out of the box?No, you always have to convert them first; the repo only ships the vendor-agnostic rule definitions, and support for a given backend depends on the separate converter/backend used.

Detection engineers, threat hunters, and other defensive security practitioners who want ready-made detection logic for their SIEM or EDR instead of writing every search from scratch.How are the rules categorized?Rules are split into Generic Detection Rules, Threat Hunting Rules, Emerging Threat Rules (for specific APT campaigns or zero-days), Compliance Rules (CIS, NIST, ISO 27001), and Placeholder Rules that get finalized at conversion time.
