  • Server side Single Sign-On to web applications using http basic authentication (when using HTTP proxy)
  • Server side DNS name resolution
  • Target server white listing
  • Support for Microsoft Internet Explorer (IE) through IE based G/On browser (GIPIE) for access to OWA, Microsoft SharePoint and other web apps, intranets and portals.
  • Support for G/On supplied “portable” Firefox browser

Other browsers that can be launched with instructions to use SOCKS and/or HTTP proxy

Other applications:

G/On’s Transparent TCP Connector provides a general port forwarding mechanism to establish authenticated, encrypted, and authorized TCP connectivity between application clients and their corresponding servers. For instance, it is possible to use the native iOS mail client on iPad and iPhone by enabling port forwards for IMAP communication between the mail client and the Microsoft Exchange Server. This option may be relevant in cases where it is considered acceptable that the native mail client for iPad/iPhone leaves copies of mails on the device for future offline use. Notice: The latest iOS 7 and later make this port forward option on iOS devices less useful and less valuable. The option depends on background processing which is now limited to 3 minutes for this type of application.
