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

"Our clients have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"Our clients appreciate that this is a security enabled solution."
"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."
"The maintenance of the solution is not complex."
"The work balancing applications are the most valuable feature."
"The stability is good, and if there is a problem, the load will be shifted to other sites automatically, which has been a good experience for us."
"I like the solution's simplicity compared to Citrix's on-prem solutions."
"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 find all of it to be valuable, because of the flexibility that is built into this product."
"Load balancing, cache redirection, content switching, all connected with traffic management."
"The solution is easy to work with and manage."
 

Cons

"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The user interface could be more friendly. Some wizards and other documentation for administrators, as well as some use cases, helps us to understand the solution."
"The main areas for improvement would be around documentation and support."
"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)."
"Citrix ADM needs to improve on its additional features and reduce the communication ports."
"It is true that it is a bit pricey compared to newer technologies coming to the market. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars."
"The configuration for its web application firewall is complicated."
"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."
"I had some problems with HA node movements."
 

Pricing and Cost Advice

Information not available

"It's an expensive product but it works well."
"We have all the features and functions of Citrix because we have a premium license."
"We have a yearly licencing fee, and there are no additional costs."
"Costly product and complicated licensing."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight or nine out of ten."
"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
