Sigma is an open source project that aims at creating a generic query language for security and D&R rules. It looks up known anomalies and Common Vulnerabilities and Exposures (CVEs).

Many people use Sigma as the community tends to respond quickly, but also puts interesting anomalies often in there.

In LimaCharlie, you can subscribe to the hundreds of rules that are a part of Sigma, for free. Every 15 minutes we re-process those rules in your organization; there's no management required, it just happens.
