Security Specialist at a energy/utilities company with 51-200 employees
Provides us with high-security access to our internal applications
What is our primary use case?
We are using it for two-factor authentication for our Citrix architecture, for secure access to our internal applications. It is mostly for admins who use it for remote access, as well as some users.
We do not use it as a web application firewall. We are running a virtual edition, not an appliance.
What is most valuable?
The most valuable feature, absolutely, is its high-security. This product is based on Unix and there have been no problems since we started using it in 2015.
What needs improvement?
Occasionally, our admin has to use the command line. If they could only use the Web GUI it would be better.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
There have been no issues with stability.
How is customer service and technical support?
We have created two support tickets and our problems were successfully solved. The support is very good.
How was the initial setup?
Set up was done by our partner and there was no problem with configuration. And most of our upgrades are done by our local partner and there have been no problems.
What's my experience with pricing, setup cost, and licensing?
We are quite happy with price. It's not too high.
What other advice do I have?
I give it a nine out of 10 because there have been no problems since 2015, from a security point of view.

Innovative TriScale architecture and SSL offloading capability
Valuable Features:
Citrix main strong-point is its flexible deployment model, which can help customers save on acquisition costs at the onset. The TriScale architecture that the Citrix sales guys have been pushing provides a pay as you grow deployment model. It also allows us to consolidate devices with features such as multitenancy and clustering. Other features like SSL offload for 2048-bit and 4096-bit key lenghts and good traffic and application reporting capabilities makes our investment in this product worthwhile.They seem to have pretty competent and responsive technical support.
Room for Improvement:
It is somewhat frustrating that there has been less feature innovations from their products. Though I really believe that Citrix’s TriScale architecture is a very innovative and successful strategy, it still lacks features such as asymmetric web content optimization which is an essential for ADCs. Also, the use of templates for ease of configuration and use also makes it a somewhat inflexible system. If you need a more advanced rules creation system then this product is not for you.
Other Advice:
I worked with Netscaler in my previous company. Overall, I recommend it. Its innovative TriScale architecture and SSL offloading capability are on par with some of the best products available. It’s a very user-friendly system that is easy to configure and use for a variety of deployment scenarios
