CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

Fenrir Simple Bash IOC Scanner

Solo incident responders and security teams without budget for commercial threat hunting platforms should start with Fenrir Simple Bash IOC Scanner; it runs on any Linux/Unix/macOS system with zero installation overhead and catches malware through hash matching and C2 detection that would otherwise require pulling logs into a paid SIEM. The 774 GitHub stars reflect actual adoption by practitioners who need fast indicator lookups during containment, not theoretical interest. Skip this if your workflow requires central logging, alerting integration, or hunting across Windows endpoints; Fenrir prioritizes speed and simplicity over NIST Respond capabilities like automated remediation.

Stairwell

Mid-market and enterprise SOC teams who need to move fast on file-based indicators will find Stairwell's hash and IOC lookup engine faster than bouncing between five different threat intelligence feeds. The tool's integration with Cortex, Chronicle, and CrowdStrike means your analysts can pivot from detection to malware variant discovery without leaving their existing workflows, and the private YARA vault lets you test and store detection logic without exposing your methodology to external platforms. Skip this if your primary pain is endpoint visibility or compliance reporting; Stairwell is built for teams that hunt actively and need to confirm whether a file hash actually matters before escalating.
