CST Verdict

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

Detectify Surface Monitoring

Mid-market and enterprise security teams that struggle to track internet-facing assets across multiple cloud providers will get the most from Detectify Surface Monitoring. Its automatic subdomain discovery and payload-based testing catch misconfigurations that passive scanning misses, and it maps directly to NIST ID.AM and DE.CM, the two functions most security teams underinvest in. Skip this if your org needs deep application scanning or prioritizes known-vulnerability remediation over asset visibility; Detectify assumes you've already cataloged what's out there and want continuous monitoring of what's exposed.
