Efficient application security while optimizing connections
The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.

Offers better visibility into user sessions compared to other solutions
Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."
"Our clients appreciate that this is a security enabled solution."
"It was very easy, the NetScaler community is very big."
"The advantage of Citrix Web App and API Protection is just its graphic user interface for beginners. The solution is nothing special, but we have to use it for the corporation. Another advantage of Citrix Web App and API Protection is that we have our copy to test things and get the know-how of it."
"I like app flows and custom flows. They integrate with multiple flows."
"Easy, user-friendly setup with content switching and integrated caching features."
"Citrix is good for application protection."
"The solution's technical support is good."
"Scalability is great. One of the best features of NetScaler is that it can scale out."
"Load balancing, cache redirection, content switching, all connected with traffic management."
 

Cons

"The support from A10 should be improved."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"Citrix should improve the documentation. It is not really clear how to set up many features to our advantage. When we setup Citrix NetScaler ADC, we have to figure it out by ourselves without a lot of documentation."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"In terms of what could be improved, I would say the user interface because sometimes it can be complicated."
"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."
"Development team's response time could be better."
"10.0 version has been buggy. We've had to patch multiple times and had a production outage trying to do App Firewall learning mode."
"The WAF component needs to be simplified so that it is easier to use."
"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."
