CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise teams protecting sensitive data in Microsoft 365 should choose Egress Protect for its post-send message control, which lets you revoke access and restrict forwarding even after recipients open encrypted email. The tool covers three NIST CSF 2.0 functions (PR.DS, PR.AA, DE.CM), with particular strength in access enforcement through granular controls and continuous audit trails that satisfy compliance auditors. Skip this if you need unified DLP across cloud storage, web, and endpoints; Egress Protect is email-centric and won't replace a platform-wide data loss prevention strategy.
