1.1.3.1 User Tier

The users of the EdgeMail system are corporate employees who may be located on the internet or on the corporate intranet. The EdgeMail complex is located behind a firewall to protect both front-end and back-end servers.

From the internet, employees may use any web browser to establish a secure connection to their corporate email and calendar accounts. Security is performed over HTTPS with SSL and certificates to verify user identity without requiring the overhead of VPN (virtual private network).

From inside the corporate network, employees may also use any web browser to view their email and calendar accounts through their familiar portal. Users may also choose to access their accounts through any IMAP email client such as Mozilla. In either case SSL is not used, further reducing overhead.
