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.
Secure and validated? Check.
The five essentials of secure email
Central administration
Manage and deploy all your certificates from a single console.
Centralized recovery
Choose from cloud-based, two-part recovery or on-premises key escrow.
Rapid deployment
Save time by using pre-configured certificate profiles designed by experts.
Flexible enrollment
Select a method that fits your needs—PKI client, self-support portal, OS/browser enrollment or Mobile Device Management (MDM) web services.
Seamless provisioning
Enjoy hands-off deployment. Automated options are available via PKI client with Gateway and Active Directory (AD) authentication, Passcode or MDM service.
