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.
Virtru Data Protection Gateway
Security teams in mid-market and enterprise organizations that need encryption enforced automatically across email and SaaS applications will get the most from Virtru Data Protection Gateway, particularly if your compliance burden includes HIPAA or GDPR and you can't afford manual encryption workflows. The platform covers PR.DS (data security) and ID.RA (risk assessment) under NIST CSF 2.0, with granular access controls and revocation capabilities that actually work post-send. Skip this if your primary concern is detecting exfiltration attempts in real time; Virtru prioritizes encryption and access control over behavioral anomaly detection.
