Beyond Encryption Mailock for Outlook
SMB and mid-market teams that need to stop encrypted emails from being forwarded or screenshotted after delivery should use Beyond Encryption Mailock for Outlook, since message revocation works even after recipients have opened attachments. The tool covers NIST PR.DS and PR.AA through AES-256 encryption and multi-factor recipient authentication, eliminating the "trust the recipient" problem that plagues standard TLS. Skip this if your org requires integration with Gmail or non-Microsoft clients; Mailock is Outlook-only and leaves users on other platforms without encryption protections.
Education institutions handling FERPA-regulated student data need CloudMask E2EE for Education because it encrypts sensitive information before it ever leaves your infrastructure, eliminating the risk that a compromised cloud provider or insider can access unencrypted records. Device-local key management and Common Criteria certification mean your encryption keys never transit through CloudMask's servers or anyone else's, which directly addresses the compliance posture FERPA auditors actually care about. This tool is overkill for districts primarily concerned with network segmentation and access controls; it's built for schools that have already experienced or narrowly avoided a cloud storage breach and want cryptographic certainty that student data stays opaque.
