CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
SMB and mid-market teams standardized on Microsoft 365 should pick Beyond Encryption Mailock for M365 if message revocation is non-negotiable; the ability to recall emails even after a recipient opens them covers the mistake you'll inevitably make sending sensitive data to the wrong person. AES-256 encryption with SMS and Q&A recipient verification handles NIST PR.AA without requiring users to manage separate identity infrastructure. Skip this if your organization needs DLP that catches data before it leaves the network or if you're already enforcing encryption at the gateway level; Mailock layers on top of M365 rather than replacing email security controls.
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.
