CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams with sprawling on-premises infrastructure and legacy systems should choose Defakto On-Prem because it kills static credentials and service accounts without forcing application rewrites. The tool covers Active Directory service account elimination, SSH certificate automation, and non-human identity issuance across VMware and mainframes, meaning you're actually reducing blast radius instead of just rotating passwords. Skip this if your estate is primarily cloud-native; Defakto's strength is the messy hybrid shop where legacy workloads never get modernized.
Enterprise security teams deploying AI agents into production need Natoma MCP Gateway because it's the only gateway that treats MCP servers as a privileged access problem rather than a developer convenience. It covers the full NIST PR.AA stack,authentication, authorization, and least-privilege enforcement,while maintaining the ID.AM and DE.CM visibility that makes shadow AI discovery actually useful instead of theoretical. Skip this if your organization hasn't yet separated AI infrastructure decisions from general API management; you're not ready for the compliance and access control overhead it requires.
