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."
"SSL Offload"
"I like app flows and custom flows. They integrate with multiple flows."
"It has helped us to increase the resiliency of the application and the performance."
"Its customer support service is good."
"It has been a very useful solution for us, allowing us to manage application accessibility even during the pandemic with complete visibility of application accessibility and any malicious activities, along with analytics reports so we can support our infrastructure in a very secure manner."
"Because of the functionality, scalability and stability of the solution as a whole, I rate ADC eight out of 10."
"Scalability is great. One of the best features of NetScaler is that it can scale out."
"What I like most about Citrix NetScaler is its stability, and I didn't see a lot of issues with it."
 

Cons

"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 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."
"A big requirement for us is to be able to scale for multi-tenancy, and this solution doesn't really provide for that."
"Citrix ADC can be really complex. It isn't very simple like some other appliances that I've worked with. You need a lot of skill and experience to manage it. I'm not talking about a year or two. You need at least four years to understand it very well. It is not that easy to learn. They should make it a lot simpler for users to understand the management of it. They can also provide some additional training. The material they have on the site is not sufficient enough for you to understand how to manage it. Their training is expensive, and not everyone has the funds and experience for it. Citrix isn't very popular around these parts of the world. So, it can use some more marketing, sales, enlightenment, and advertisement. These could bring more market for them. Basically, there are just a few companies that really go for Citrix. Most of the companies go for VMware because they marketed themselves more than Citrix. There isn't much difference between Citrix and VMware. VMware is a little more robust than Citrix. Citrix has focused more on desktops rather than server virtualization, and that's the advantage VMware has over Citrix. Citrix also needs to educate and inform users about the infrastructure that is supported with a version. Currently, if the customers don't look at the datasheet, they might miss this important information."
"It should offer more flexible cost-effective licensing for small to medium sized organizations i.e. a pooled licensing option on entry level MPXs like 5901s."
"Maybe creating policies with simple regular expressions."
"Its scalability is not good enough. We can't scale the model that we have to the one that is used for multi-tenancy."
"If one device or switch fails, the failover to another device is not seamless which is painful."
"The main areas for improvement would be around documentation and support."
"We are looking for some in-depth monitoring and analytics and more information that Citrix Director doesn't provide. ControlUp has insights that not only give you an overview but also allow you to do some drill-down troubleshooting for what's going on in your environment. We are looking for some more analytical and monitoring data to be able to monitor the environment better, not only from an application standpoint but also from the standpoint of the infrastructure to everything it sits on. They can provide more data to the administrators about what's going on within the application. They can provide data not only on the application side but also about what the application sits on. They're making strides with Citrix Analytics in regards to that."

Each product has its advantages, and combining certain features of F5 and NetScaler could be beneficial. I'd rate the solution eight out of ten.

Regarding pricing, educational institutes often receive better prices. In the context of virtualization, prices are increasing, affecting small to medium businesses in Israel.
