Access Gateway discussed in this blog is the Access Gateway based on NetScaler, which is popularly referred to as Access Gateway Enterprise.

License Types

Access Gateway is licensed at two levels:

Platform licenses can be used to provide seamless access to:

  • ICAProxy access to XenApp / XenDesktop, using Web Interface
  • ICAProxy access to XenApp / XenDesktop, using Storefront (CloudGateway Express)
