NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections).

The most valuable feature would be the Citrix permanent server, as it is cost-effective if you consider the permanent server and the management is easy with no downtimes.

I would like to see support for scripting, like "iRule", which gives you the option to implement any configuration which is not available out of the box.

The product provides some templates to integrate with applications like MS Exchange, MS SharePoint, SAP Enterprise Portal, and others. However, the last update for these templates was 2013 (lots of applications are running on versions newer then 2013).

Scripting and writing expressions need to be improved by putting logic behind the rules and improve policies involving some of the scripting part, which is a tedious task to do.
