LUMEN

LUMEN is a browser-based Windows Event Log analyzer built with React and WebAssembly that processes EVTX files entirely client-side without uploading logs to external servers. It supports files up to 500MB with both binary EVTX and XML exports. The tool features a curated SIGMA detection engine with platform-specific rule loading, automated event correlation that chains related activities into investigative storylines, IOC extraction with optional VirusTotal integration, and AI-powered analysis. Security teams can perform guided investigations while maintaining complete data privacy through local-only processing with session persistence via localStorage and no telemetry or data transmission.
