CST VerdictBased on our analysis of available product data, here is our conclusion:
Windows incident responders and threat hunters working inside corporate networks will get the most from Fibratus because it gives raw kernel-level visibility into process behavior without the licensing cost of commercial EDR. It's free and open-source with 2,373 GitHub stars, which means you're getting tested code plus a community that actually uses it for real investigations. Skip this if you need cross-platform coverage or graphical case management; Fibratus is Windows-only and command-line driven, built for practitioners who think in system calls, not dashboards.
Incident responders who need to collect forensic artifacts from Windows hosts fast will appreciate CyLR's minimal footprint and speed; it grabs what matters without the bloat of full-disk imaging. The tool is free and maintained on GitHub with 714 stars, meaning you're not paying for licensing and the codebase gets real-world scrutiny. CyLR prioritizes collection over analysis, so you'll need a separate tool to process and examine artifacts once they're gathered; it's a triage accelerant, not a complete DFIR platform.
