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 appreciate that this is a security enabled solution."
"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."
"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."
"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."
"If a company wants to have a secure environment and they want the performance then this is a good solution."
"One of the most beneficial features for application delivery is its integration with Citrix Storefront, facilitating user logins and ensuring continuity during data center outages."
"We have good customer support."
"It's very easy to configure."
"Content filtering, security layer, and application customization features are the most valuable."
"The most valuable feature is the content switching."
"For desktop application management, I recommend the NetScaler edition; this product is like a Swiss army knife and Citrix NetScaler ADC supports the education front-end."
 

Cons

"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"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."
"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."
"There are some features which are missing.​"
"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 had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers."
"The solution could be more secure."
"Needs configuration processes like disabling LB VIPs, automatically disabling the IPs used."
"In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it."
"I feel that Citrix NetScaler's customer support needs to improve."
 

Pricing and Cost Advice

Information not available
"In Turkey, everything is good, but it seems expensive for us due to the currency exchange. I don't have a specific rating scale, but if I had to rate the price, I would say it's around a six out of ten."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"Ninety day free trial makes it easy to try out this solution."
"The solution is expensive compared to one of its competitors."
"F5 BIG-IP is much more expensive than Citrix ADC. For example, If we choose two platforms, Citrix ADC, 3000 version, and we choose F5, F4200 version. F5 BIG-IP has connections, timers, and throughput similar to Citrix ADC, but the price is very expensive."
"Its licensing cost is much higher than other products, but it is acceptable because it is a one-time investment, and we are getting our requirements fulfilled when we buy this product. So, there is no issue with the pricing."
"Our licensing fees including technical support are approximately $3,500 USD."
"The solution is undoubtedly very good, but it is expensive."
