Open Source Go SIEM Tools

Fibratus is a free, open-source Windows security monitoring tool designed for real-time threat detection, endpoint protection, and forensic analysis. It observes operating system activity through Windows Event Tracing to identify potentially malicious behavior. Its behavior-driven rule engine detects suspicious processes, file operations, network activity, and other security-relevant events. YARA integration enables memory scanning for malware signatures and suspicious patterns. Users can investigate system events, correlate activity, and develop custom detection rules. Captured events can be stored for forensic examination or forwarded to external monitoring systems. Python-based filaments extend the application with custom analysis and automation capabilities. Fibratus helps security analysts identify attacker techniques, investigate incidents, and strengthen Windows endpoint defenses.
