Access Gateway is licensed at two levels:
- Platform License
- Universal License
Every Access Gateway (VPX/MPX) comes with a Platform license, which enables all the basic functionality in Access Gateway. After purchasing an appliance, this license is automatically made available in your MyCitrix account, and can be easily downloaded and installed on your appliance.
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)
