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

"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."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"Our clients have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"The most valuable features are the VDA Delivery, Gateway Fort, and the load balancing."
"We appreciate that this solution facilitates our access to Citrix internet."
"Available on any device and can be accessed on a wide area network."
"Because of the functionality, scalability and stability of the solution as a whole, I rate ADC eight out of 10."
"The most valuable feature would be the Citrix permanent server, as it is cost-effective if you consider the permanent server and the management is easy with no downtimes."
"The web application firewalling component is a powerful feature."
"It has helped us to increase the resiliency of the application and the performance."
"The most valuable feature of Citrix ADC is its ease of use."
 

Cons

"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"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."
"The support from A10 should be improved."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"It is difficult to customize. It is more difficult to customize than F5, for example."
"There's nothing special with the solution in terms of protection and no notification if there's an issue, so Citrix Web App and API Protection does not have much use."
"The interface needs to be improved because the competition is coming up with ones that are more eye-catching, straightforward, and sophisticated."
"The main areas for improvement would be around documentation and support."
"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."
"Citrix is more expensive than Horizon."
"The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though."
 

Pricing and Cost Advice

Information not available
"Our licensing fees including technical support are approximately $3,500 USD."
"You can do CapEx and then a yearly monthly fee, or you can do a subscription model, whether that's one month, month-to-month, or three-year subscription model."
"Costly product and complicated licensing."
"NetScaler does the same thing as an F5 and it's cheaper."
"I rate the pricing an eight out of ten since it is expensive."
"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"
"The solution is expensive compared to one of its competitors."
"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."
