NetScaler is available in either a hardware or software-based appliance. Hardware options include single and multi-tenant devices, in addition to FIPS compliant and high SSL appliances. Software-based options include virtual hypervisor-based and containerized microservice offerings. All appliances require a specific NetScaler software edition to be paired with the specific model being selected (with the exception of the containerized NetScaler CPX which is not available in different editions).

Types of NetScaler Gateway Licenses
- NetScaler Gateway Express License: The Express license is used with the NetScaler VPX and allows for up to five concurrent user connections by using Receiver or the NetScaler Gateway Plug-in. The Express license is available for the VPX appliance and expires after one year. Users can connect to either Basic or SmartAccess virtual servers.
- NetScaler Gateway Platform License (ICA license): The Platform license allows unlimited user connections to published applications on XenApp or virtual desktops from XenDesktop. Connections using Citrix Receiver do not use a NetScaler Gateway Universal license. These connections only need the Platform license. The Platform license is delivered electronically with all new NetScaler Gateway orders, whether physical or virtual. If you already own an appliance covered by a warranty or maintenance agreement, you can obtain the Platform license from the Citrix web site.
- NetScaler Gateway Universal License (CCU license): This license allows VPN connections to the network from the NetScaler Gateway Plug-in, a SmartAccess logon point, or Secure Hub, Secure Web, or Secure Mail.
The Universal license limits the number of concurrent user sessions to the number of licenses you purchase. If you purchase 100 licenses, you can have 100 concurrent sessions at any time. When a user ends a session, that license is released for the next user. A user who logs on to NetScaler Gateway from more than one computer occupies a license for each session.
