CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams running lean reconnaissance workflows will extract subdomains faster with censys-enumeration than querying certificate databases manually, since it automates SSL/TLS enumeration across Censys' dataset at zero cost. The 152 GitHub stars signal active use among practitioners who value simplicity over UI polish. Skip this if you need continuous monitoring or automated alerting on new discoveries; this is a one-time enumeration script, not a managed platform that rescans your attack surface on a schedule.
Mid-market and enterprise security teams drowning in external asset sprawl will get immediate value from Guardz External Footprint because it actually monitors your dark web exposure instead of just scanning open ports. The tool covers all four critical NIST ID and DE functions, with particular strength in continuous monitoring and asset discovery across DNS, TLS, and credential leak channels. Skip this if your organization has already mapped and locked down your external footprint; Guardz is built for teams still discovering what's actually exposed.
