sagan
Sagan is an advanced log analysis engine similar to Suricata and Snort, designed for high-performance monitoring and threat detection. Developed by Champ Clark III and the Quadrant InfoSec Team, it processes and analyzes log data in real time to identify suspicious activity, security events, and policy violations. Sagan supports a flexible rules-based detection engine, multi-threading for speed, and compatibility with existing rule formats. It is commonly used by security professionals, network administrators, and SOC teams for correlating logs, detecting intrusions, and enhancing situational awareness across enterprise environments.
