Support for scripting needs enhancement, such as implementing features like iRule for customized configurations.
Existing documentation and support need improvement as it lacks coverage of multiple use cases and clear guidance.

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).

Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)

The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications.

HTTP analysis and action. We have a lot of custom web applications that sometimes require custom header insertions. Some of these custom apps are external and, via the content switching, we can use one IP and leverage various back-end web app servers.

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.

I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand.

We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers.

The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support.
