CST Verdict

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

Recog

Security teams running manual threat hunts or building custom detection workflows will extract the most from Recog because its fingerprinting approach identifies obscured services and hardware that signature-based tools consistently miss. The 742 GitHub stars and active community fork activity signal real adoption in IR and red team environments, not just a proof-of-concept framework. Skip this if you need automated scanning at scale or point-and-click ease; Recog demands operational knowledge to tune probes and interpret results, which is exactly why experienced hunters prefer it.
