Based 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 encryption without forcing end-users through client installation will find SecurelyShare for Email cuts through adoption friction; the agentless architecture means you encrypt at the gateway while recipients access messages through their existing email client. Policy-based automation handles both the encryption enforcement and the audit trail compliance that NIST PR.DS and GV.PO require. Skip this if your organization relies on external recipients who refuse web portal workflows or if you need encryption to cover non-email channels; SecurelyShare stays focused on email.
