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 and malware analysts who need to see exactly what an untrusted binary is doing at the API level should use Drltrace, a free dynamic tracer that captures Windows and Linux syscalls with minimal setup friction. The 418 GitHub stars and zero licensing cost mean you can deploy it across your lab and production triage workflows without budget negotiation. Skip this if you need post-execution forensics or behavioral analysis beyond raw API calls; Drltrace is narrow by design, showing you what happened in real time but not synthesizing that data into threat scores or automated response actions.
