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.

Teams handling regulated data who need proof that sensitive emails were opened, not just sent, should consider Beyond Encryption Mailock® Secure Email; message tracking and revocation give you the audit trail that generic TLS encryption cannot. AES-256 encryption with multi-factor recipient verification covers the NIST PR.DS and PR.AA controls auditors actually ask for. Skip this if your priority is preventing internal data exfiltration rather than securing external communication; Mailock assumes the recipient's inbox is the trust boundary, not an extension of your network.
