Beyond Encryption Mailock for M365 vs Virtru Email Encryption: Side-by-Side Comparison (2026)

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 Email Encryption

Mid-market and enterprise teams that need email encryption without forcing users through clunky workflows should start with Virtru Email Encryption. The one-click Gmail and Outlook plugin adoption rate beats password-protected PDFs by orders of magnitude, and its data revocation capability,pulling back sent emails after delivery,addresses the real compliance gap competitors ignore. Skip this if your organization treats email encryption as a compliance checkbox rather than a security control; Virtru's granular access controls and audit trails assume you'll actually manage who sees what, not just encrypt and forget.
