Beyond Encryption Mailock Free vs Beyond Encryption Mailock for M365: 2026 Comparison

Beyond Encryption Mailock Free

Individuals and small teams who need to send encrypted email occasionally will appreciate Mailock Free's zero-friction setup; the Q&A recipient authentication means recipients don't need accounts or plugins, just answers to your challenge questions. Five secure sends monthly plus unlimited replies covers light compliance needs like sharing passwords or contract drafts with external partners, and GDPR compliance support matters if you're in Europe. Skip this if you need more than five outbound encrypted messages per month or require integration beyond Outlook; the free tier's hard send limit makes it a toy for anyone doing regular secure email, not a replacement for proper gateway encryption.

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.
