Beyond Encryption Mailock for M365 vs Virtru Google Workspace Encryption and Data Privacy: Side-by-Side Comparison (2026)

Short answer

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. Teams invested in Google Workspace who need encryption that doesn't break user workflows will see immediate value in Virtru Google Workspace Encryption and Data Privacy, since it encrypts Gmail, Drive, Meet, and Docs natively without forcing users into separate portals. FIPS validation and private key hosting mean you can satisfy compliance auditors without pretending Google holds your encryption keys. Skip this if your organization runs email outside Google Workspace or needs DLP that catches exfiltration before it leaves your network; Virtru prioritizes encryption and access control over anomaly detection.
