CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams managing legacy mainframe infrastructure alongside cloud systems should pick Tectia SSH Server for its native IBM z/OS support, which eliminates the awkward workarounds that plague competing SSH products in hybrid environments. The product maps cleanly to NIST PR.AA and PR.DS, handling both access control and data confidentiality without requiring separate tools for mainframe-to-server file transfer. Skip this if your environment is purely cloud-native or you need integrated endpoint detection; Tectia is SSH infrastructure, not a broader access management platform.
Mid-market and enterprise security teams managing Microsoft 365 collaboration will pick eSHARE to eliminate guest account sprawl without sacrificing external file sharing, a common friction point between security and business units. The tool enforces DLP policies natively within M365 while keeping data resident in your tenant, which maps directly to PR.AA and PR.DS controls under NIST CSF 2.0. Skip this if your organization needs DLP enforcement across non-Microsoft SaaS applications or prioritizes on-premises deployment; eSHARE is built specifically for M365-first shops that want governance without the operational debt of managing external user accounts.
