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.
Compliance officers and security teams in defense contracting, aerospace, and healthcare managing ITAR or CMMC-regulated data need PreVeil Email because it encrypts sensitive messages end-to-end without requiring email infrastructure replacement or asking users to abandon Gmail and Outlook. The tool holds FedRAMP authorization and FIPS 140-3 validation while letting subcontractors access encrypted content for free, eliminating the licensing friction that kills adoption on classified programs. Skip this if your organization needs data loss prevention rules, content inspection, or the ability to revoke sent messages; PreVeil's zero-knowledge architecture means PreVeil itself cannot intercept or unsend encrypted traffic.
