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 that need to move sensitive files outside email will find FTAPI Platform's zero-knowledge architecture and 100 GB attachment capacity genuinely useful, especially where GDPR compliance matters; the German data center residency and automated key exchange eliminate the certificate-management friction that kills adoption on competing platforms. The E2E encryption across SecuMails, SecuRooms, and SecuForms covers the three workflows where encryption actually breaks down in practice. Skip this if your primary need is detection and response; FTAPI covers data security and asset management but leaves incident response largely to you.
Mid-market and enterprise teams handling sensitive email workflows,healthcare, finance, legal,should evaluate StealthMail primarily for its recall and access control capabilities; most competitors encrypt content but can't revoke it post-delivery or prevent forwarding, and StealthMail does both. The hybrid deployment model and user-owned key management (ECC 512+) mean you're not trusting the vendor with your encryption material, which covers the PR.AA and PR.DS functions that matter most for regulated industries. Skip this if your threat model centers on detecting account compromise rather than preventing lateral movement of sensitive emails; StealthMail is a content-control tool, not a mailbox forensics platform.
