Prelude SIEM is an open-source security information and event management system built on the IDMEF standard (RFC 4765). Originally developed by SoundCloud, it offers both a free OSS version and a commercial edition. The system provides real-time monitoring, event correlation, and threat detection with native compatibility for multiple IDS systems including Snort, Suricata, OSSEC, Wazuh, and over 30 types of system logs. While the OSS version has performance limitations for small environments, the commercial version delivers enterprise-grade capabilities with enhanced scalability and professional support.
