A Private Email Network (PEN) is a way for individuals or organizations to retain control of the information that they send over email without adopting a whole new system of communication. We accomplish this by introducing a webservices based architecture, using an HTTPS protocol (128-bit SSL encryption – the same level of security used for online banking) to transport email messages and attachments. This new architecture works in conjunction with basic email, so users can continue using the same email address and email programs.
When you have a Private Email Network (PEN), you control it. You decide who belongs and who doesn't. When someone isn't a member of you PEN, they are completely locked out.

Access to your PEN is granted by means of a simple to use, lightweight email2 Toolbar for your existing email client. If you do not want to install the email2 Toolbar, (or if your email client isn’t supported), you can still make full use of email2 through the email2 Web Client – a secure, interactive web application that runs on all Internet browsers, Mac, PC and mobile devices.
