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.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.

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 have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"Our clients appreciate that this is a security enabled solution."
"It has helped us to increase the resiliency of the application and the performance."
"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."
"This solution can be deployed on-premises, public cloud, and private cloud; it's hybrid, it's a good product and I recommend it."
"The NetScaler appliance has provided a lot of customers with greater high availability for their enterprise applications within a single site and across multiple locations."
"Compared to other solutions, Citrix ADC is much more robust in terms of the native integration to cloud platforms, and it is far more robust from an operational point of view as well."
"The most valuable feature is the capability of performing load balancing in a virtual environment."
"I like app flows and custom flows. They integrate with multiple flows."
"One of its most valuable features is fundamental load balancing, supporting both basic load balancing and database teams."
 

Cons

"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 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."
"Alert Management could be improved."
"Integration with other third party providers and third party applications could be better because it can be a bit complex at present."
"It does not have a sandbox cloud service and antivirus. It should have on-prem or cloud sandboxing and antivirus."
"Scripting and writing expressions need to be improved by putting logic behind the rules and improve policies involving some of the scripting part, which is a tedious task to do."
"Overall the price of Citrix ADC could be more competitive."
"The solution has too many bugs in the software and it's always difficult when you need to update."
"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."
"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."
