SSL Network Extender is a secure connectivity framework for remote access to a corporate network. SSL Network Extender uses a thin VPN client installed on the user's remote computer that connects to an SSL-enabled web server. The web server and the client are in the same VPN.

Note: SSL Network Extender requires that Java is installed on the endpoint computer. Java is not installed on Mac OS X 10.7 (Lion). For more information see sk65144 (SSL Network Extender - Java Availablity).

What's New

These features are new for SSL Network Extender E75:

  • Support for Mac OS X 64-bit.
  • Support for new Linux platforms 32 and 64-bit.
  • Proxy server auto-detection is now supported for browsers that run Java or ActiveX.
  • Improved user experience that explains how to install Java when necessary.

E75 Documentation

Important: You must read the instructions in the Release Notes before installing the relevant download.


E75 Downloads

Important: Installing SSL Network Extender consists of two parts:

  • Upgrading SSL Network Extender on Security Gateways
  • Deploying the clients from the Security Gateways to endpoint devices

Upgrading SSL Network Extender on Security Gateways depends on your Security Gateway. Select the hotfix link that is relevant for your Security Gateway version and OS. Then you can continue deploying the clients from the Security Gateways to endpoint devices, as per the instructions provided in the SSL Network Extender E75 Release Notes.

Note: In order to download some of the packages you will need to have a Software Subscription or Active Support plan.
