Email Encryption Services The ZixCorp email encryption service delivers encrypted messages to anyone through flexible delivery options. Encrypted email is automatically delivered in the manner that works best for the end user through our Best Method of Delivery™ capability. ZixCorp supports desktop and gateway clients using a variety of encryption standards such as S/MIME, OpenPGP and TLS. In addition, ZixCorp provides two different methods of delivering encrypted emails to users that do not have encryption capabilities. These clientless delivery options include a secure portal “pull” and direct delivery “push” model. No matter what the email encryption capabilities of the recipient, ZixCorp will encrypt and deliver email to them. Unlike any other solution, the ZixCorp Email Encryption Service allows all customers to communicate seamlessly and securely with no additional work. Every ZixCorp customer is added to the ZixDirectory, our global repository with more than 7 million members. Using the ZixDirectory, our customers do not have to build their own directory of encryption keys for all of their partners and customers. Competitive solutions lack this feature making them cumbersome and difficult to use. The best security solutions are those that are easy to use, like the ZixCorp Email Encryption Service.
