How S/MIME Works
Digital Signature:
- The signature is generated with a private key and authenticated using the public key
- The public key/certificate is transmitted with the S/MIME protected email
- When the recipient opens the email, the public key verifies the signature
- Every time you create and sign an email, your private key applies your unique Digital signature into your message
Encryption:
- The sender must have access to the recipients S/MIME certificate
- Content is encrypted using a public key and can only be decrypted with the private key
- SSL/TLS provides an encrypted tunnel through which the email is sent
- S/MIME encrypts the email message
Three Levels of Validation:
- Individual—requires phone call, government issued ID and a valid email address, the certificate identifies an individual's name
- Role within an organization—requires a phone call, valid legal existence of the organization and verified employment, these certificates identify the individual and organization name
- Organization—requires a phone call to the Organization representative and Key Custodian, a valid legal existence of the organization and email domain, this certificate identities the organization name

S/MIME Deployment Reinvented
Sectigo's Zero-Touch S/MIME is the first and only solution that integrates directly with Microsoft Active Directory to automate issuance and deployment of S/MIME certificates across an entire organization.
- Deploys thousands of S/MIME certificates instantly
- Installation is automated, no going device by device
- Easily enroll new employees and revoke departing ones
- Automate renewals and key rotations
Historically, the only barrier to adoption with S/MIME certificates was the tedium involved in deploying them all and managing them across large networks. Not anymore. Sectigo's Zero-Touch S/MIME reduces thousands of installations down to just a few clicks.
