Nearly all other secure e-mail solutions make use of complicated e-mail encryption systems such as the Public Key Infrastructure (PKI). While these methods encrypt the message and provide reliable security for one-way travel, they still rely on the basic e-mail architecture (SMTP Route) to deliver these encrypted e-mail messages. As a result, they still cannot track, audit or recall messages. Even worse, once a message leaves your computer, there is no guarantee that it is protected. PKI solutions are still limited by attachment sizes and offer no additional productivity enhancements. Furthermore, managing the required encryption keys for all the users makes it almost impossible to control.

email2 achieves security by introducing a webservices based architecture using an HTTPS protocol (128bit strong SSL encryption, the same level of security used for online banking) to transport secure messages and attachments while allowing users to retain the same e-mail address and e-mail programs. Content and attachments are still encrypted, but only once they hit the Private Email Network, making the whole process seamless for all users.

email2 requires no special effort on the part of a user to keep an email2 message safe - no encryption keys to deploy and manage, no complicated processes to renew certificates, etc.
