Secure Email S/MIME Hero
Secure Email Certificates (S/MIME)

Secure every email from
draft to delivery

Automate signing and encryption for your most-hacked
medium with quickly deployed client (S/MIME) email
certificates. That’s digital trust for the real world.

A more sophisticated attack

Attacks from cybercriminals are becoming more sophisticated all the time. Where fraudulent emails were once much easier to detect—even by the untrained eye—today's spoofing and phishing emails can be mistaken for legitimate communication, even by educated users.

A more trusted defense

PKI email encryption defends against phishing, spearhead phishing, spoofing and other forms of email fraud. Using S/MIME email signing certificates, PKI encrypts messages and attachments in transit and signs them, binding the verified identity of the sender to the email itself.

Put trust in your messages

Secure email certificates provide

Authentication, encryption and data integrity for email

For many organizations, the unsuspecting recipient of an email is the most worrisome attack vector. As with websites and bank transactions, email data needs to be protected while it’s moving from sender to recipient and at rest wherever it’s stored. Email certificates offer a proven PKI email encryption and authentication solution that not only secures the content of the email, but it also embeds the verified identity of the sender.

With DigiCert® Trust Lifecycle Manager, you can control and administer all your email signing certificates from one place. No matter how many people are in your organization, all your communications can be protected and validated with ease. Integrate corporate email services, authenticate users, remove former employee access and recover secure emails—all from one sign-on.
