Beyond Encryption Mailock Automated
Mid-market and enterprise security teams handling high-volume regulated communications will benefit most from Mailock Automated because it encrypts and delivers sensitive emails at scale without forcing recipients through portal logins or registration friction. The tool supports ICO and FCA compliance requirements out of the box and requires zero recipient setup, which materially reduces support overhead and delivery failures in organizations managing thousands of encrypted messages monthly. Skip this if your primary need is inbound email filtering or threat detection; Mailock is encryption-and-delivery focused, not a full email security platform.
DigiCert Secure Email (S/MIME) Certs
Organizations that need legally defensible email encryption without rebuilding their mail infrastructure should start with DigiCert Secure Email (S/MIME) Certs. S/MIME works natively in Outlook, Gmail, and Apple Mail, meaning adoption friction stays low and you avoid the gateway appliance tax. The tool maps directly to NIST PR.AA (authentication via public/private key pairs) and PR.DS (message-level confidentiality and integrity), covering the core email security control most compliance auditors actually care about. Skip this if your threat model demands perfect forward secrecy or sender anonymity; S/MIME signs identities, not conceals them.
