We use Citrix Netscalers for web application security and acceleration. In order to test some things before a deployment of some new Netscalers we wanted to test then using Citrix's Netscaler VPX virtual appliance (http://www.citrix.com/netscalerVPX).

If you're having problems passing your vulnerability scans and you have a Citrix Netscaler Application Delivery Appliance, here are the links to the Citrix KB articles which describe how to resolve the issue.
