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.
Mid-market and enterprise teams that need to move sensitive files outside email will find FTAPI Platform's zero-knowledge architecture and 100 GB attachment capacity genuinely useful, especially where GDPR compliance matters; the German data center residency and automated key exchange eliminate the certificate-management friction that kills adoption on competing platforms. The E2E encryption across SecuMails, SecuRooms, and SecuForms covers the three workflows where encryption actually breaks down in practice. Skip this if your primary need is detection and response; FTAPI covers data security and asset management but leaves incident response largely to you.
