Beyond Encryption Mailock for M365
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 handling sensitive data under GDPR or NIS-2 should use FTAPI SecuMails if your workflow lives in Outlook and you need encryption that doesn't burden recipients. The Outlook Add-in works across both new and classic versions, centralized S/MIME certificate management eliminates the renewal headache, and recipients need no special software to decrypt,that's friction eliminated at scale. Skip this if your threat model requires detection and response capabilities beyond encryption, or if you're standardizing on cloud-native email security platforms outside the Microsoft ecosystem; FTAPI SecuMails solves the encryption problem cleanly but doesn't replace CASB or advanced threat detection.
