A more trusted defense

Authentication, encryption and data integrity for email

In many organizations, email is the weakest security link. As with websites and bank transactions, email data needs to be protected while it’s moving from sender to recipient. PKI certificates offer a proven encryption and authentication solution that not only secures the content of the email, it also embeds the identity of the sender.

With DigiCert® Trust Lifecycle Manager, you can control and administer all your email certificates from one place. No matter how many people 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.
