VNC Enterprise Edition is an enhanced version of the industry-standard VNC, developed for use in corporate environments and across the Internet. Designed and built from the ground up by the original inventors of VNC, Enterprise Edition provides robust and easily-administered security with a minimum of fuss.

The core Enterprise Edition features, common across all supported platforms, are as follows.

Integrated Session Security provides protection from connection snooping, man-in-the-middle attacks and packet-tampering attacks, to name but a few.
Server Authentication uses 2048-bit RSA keys to verify identity.
Viewer Authentication supports both usernames and passwords of up to 256 characters each.
Secure Communication with 128-bit AES—the experts' choice for high performance encryption.
Platform-Native Authentication removes the need for separate VNC and system passwords. Users can access their desktops using the same credentials with which they log on to the system.
One-Port HTTP & VNC allows VNC Server to serve VNC Viewer for Java and VNC sessions through a single TCP port, simplifying NAT and firewall configuration.
Cross-Platform Interoperability with the other members of the VNC Enterprise family.
Free Upgrades for the first 12 months. Continuing support and upgrades for a competitive annual fee.
