Detection rules for CyberSift.io and Sentio SIEM, written in JMESPath and maintained as version-controlled detection content.
This repository provides a practical rule library for identifying suspicious activity across structured security events. Rules are designed to be readable, reviewable, and easy to manage as part of a modern SIEM detection workflow.
CyberSift helps security teams collect, analyze, and act on security telemetry through Sentio SIEM. This rule repository supports that workflow by keeping detection logic transparent and maintainable.
Each rule is written using JMESPath, a query language for JSON data. This makes the rules well suited for evaluating normalized event data and expressing detection logic in a clear, consistent format.
