Sagan – multi-threads, high performance log analysis engine

Sagan is billed as the advanced Suricata/Snort like log analysis engine.

It uses a multi-threaded architecture to deliver high performance log & event analysis. Sagan’s structure and rules work similarly to the Snort or Suricata IDS/IPS engines. It maintains compatibility with rule management software (oinkmaster/pulledpork/etc) and allows Sagan to correlate log events with your Snort/Suricata IDS/IPS system.

Sagan is free and open source software.

Features include:

  • Automate log management:
    • Supports many different output formats.
    • Log normalization.
    • Script execution on event detection.
    • GeoIP detection/alerting.
    • Multi-line log support.
    • Time sensitive alerting.
  • Multi-threaded architecture allows it to use all CPUs / cores for real-time log processing.
  • CPU and memory resources are lightweight.
  • Built in JSON parsing.
  • Similar rule syntax to Cisco’s “Snort” which allows for easy rule management and correlation with Snort or Suricata IDS / IPS systems.
  • Store alert data in Cisco’s “Snort” native “unified2” binary data format or Suricata’s JSON format for easier log-to-packet correlation.
  • Intra-Process communications between Sagan processes to share data. Sagan can also use Redis (beta) to share data between Sagan instances within a network.
  • Compatible with popular graphical-base security consoles like Snorby, BASE, Sguil, and EveBox.
