Imperva CDN vs. NetScaler ADC

I recommend it as a WAF, but not as a CDN. There are better CDNs, in my case I use transparentCDN (now www.transparentedge.eu) and Edgecast (now Verizon CDN).

Citrix Netscaler can be a powerful network appliance for environments that are fully committed and open to utilizing a network appliance that isn't made by a traditional network vendor. Administrator user experience has improved over the years and will continue to improve with the flexibility of virtual and physical appliances available for medium and large enterprises.

• Reliability / Uptime

• Flexibility. NetScaler assumes its admins know a bit about networking and in-depth details surrounding the applications they are configuring access for/to. This being so, the range of configuration options is very broad allowing various versions' combinations of protocol patterns, expressions, rules etc., all to the benefit of the admin.
• Granularity. Having such a broad range of configuration options available, while still allowing simple options to be configured simply. The GUI is well-stylized and navigation has a good flow.
• Ease of control. For load-balancing of simple services right out of the box, NetScaler makes it pretty easy, compared to the range of options available in the surrounding GUI and under the hood.

• CDN functionalities are secondary and cannot be compared to a top-level CDN.
• The WebGUI interface of the dashboard is very improvable. They have been changing the UX for years and it is disjointed and with services that have not yet been migrated.
• The analysis of WAF attack logs is insufficient. It is difficult to analyze attacks of past hours, event filters are missing. It is complicated to analyze the chronology of an attack.
• There are extra modules to improve the attack logs analysis but they are expensive and add little.

• The documentation could use an overhaul with specific examples related to the command line as well as GUI. Explanations in the documentation would also be helpful.
• Being able to have more than just one routing table would allow the ability to leverage security.

Improve on the specifics I mentioned previously and could be a 10/10 product. It is also a confusingly branded product that I have supported in two large enterprises where IT departments are unsure if the product belongs to the Citrix remote access support team or the Network infrastructure support team (it should be the later) and typically under utilized.

Overall, our organization's experience with Citrix support is that support can be hit or miss. Oftentimes it takes multiple attempts and much longer than desirable to obtain a viable solution for issues experienced with their products. It would be great to see Citrix invest time, effort, and almighty dollars into improving their support and bug fix process across the board.

Also TransparentCDN (now www.transparentedge.eu ) and Level 3

We chose Citrix ADC over Kemp and F5 due to additional integrations with various products such as Citrix/Horizon/Monitoring tools. We additionally chose ADC due to better ease of use and ability to have the appliances be virtual or physical, with the configuration being a simple migration of code which provided flexibility to be able to do a hybrid environment with ease.

• It's an expensive product if you have a lot of traffic volume, but I feel confident with their WAF.

• It has saved a tremendous amount of money and manpower by allowing for broad support without the need for a VPN.
• The security functions within Netscaler enabled our business to pass additional IT-based audits.
• Having a full Citrix stack from front to back makes our business look more professional both to our users and outsiders.
