We performed a comparison between A10 Networks Thunder ADC and Citrix NetScaler based on real PeerSpot user reviews.
Find out in this report how the two Application Delivery Controllers (ADC) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Being a public entity and having a public website which is highly visible with a lot of traffic, we are a target for DDoS. Within the last year, we have had a couple of DDoS attacks which could have affected our web traffic and taken down certain parts of our website. This did not happen because the A10 was able to mitigate the attacks using rate limiting that can be configured for DDoS mitigation on the box."
"The Global Server Load Balancing (GSLB) is simple to use."
"The ADCs are pretty straightforward and easy to use. There is a GUI base where you can go in and see everything, but they also have a CLI base where you can use a command and get the information that you want, very fast."
"The Deterministic CGNAT feature is valuable for us."
"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."
"The DNS application firewall and load balancing are very valuable."
"The solution is stable."
"Scalability is great. One of the best features of NetScaler is that it can scale out."
"Provides resiliency for applications that reside on servers, as well as connectivity to remote applications."
"One of its most valuable features is fundamental load balancing, supporting both basic load balancing and database teams."
"We appreciate that this solution facilitates our access to Citrix internet."
"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."
"Load balancing, cache redirection, content switching, all connected with traffic management."
"NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections)."
"I would say the rewriting and redirection functions are must-have's for us."
"The solution should add automation features in the next release."
"The interface and integrated custom applications can be a bit difficult."
"The user interface is what people complain about most of the time, particularly if they don't use it very often. Then they complain that it's a bit clunky."
"In my opinion, they need to improve their cloud support. There is support for cloud, but not all functions are there, such as high-availability."
"A10 Networks Thunder ADC could improve on the Application Delivery Controller. it's not a fully-fledged web application firewall solution. For example, application data and support need to improve."
"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."
"There are competitors that have more features."
"The tool's load-balancing feature should improve."
"Some of our customers have questioned the security of this solution lately, wondering whether it is safe or not, so enhancements in this respect would be good."
"Technical support could be improved."
"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."
"The solution could be more secure."
"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."
"The solution should be able to scale more effectively than it does."
"Citrix NetScaler has been recently acquired by another company and the support has been negatively impacted, the solution is at its end of life. The support for the solution could improve. The sales team needs to be improved."
"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."
