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."The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"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."
"We have two appliances and I'm able to move my application from one appliance to another. I don't have to move my whole A10 to be active on the other side or to be passive on the other side. If an application is having a problem, I can just move it using a command."
"The ease of use is very good. It's very robust. It just sits and works."
"The SLB and GSLB load balancing are the most valuable features. They meet our need to do server-side load balancing and global site load balancing so we can distribute traffic, not only intra-data center, but inter-data center."
"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."
"It helps with the efficiency of application deployments and data security."
"It is very useful to have a simple dashboard where you can login and look into what your traffic patterns are, then look and see what times of day you're experiencing the heaviest traffic. You can quickly identify if you are possibly having a security issue or security breach. It makes it very easy to use the box."
"It is the best product out there."
"Content Switching provides flexibility for routing traffic as desired to designated real servers. It also provides good geo capabilities through its GSLB feature."
"Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"My clients use it for load balancing."
"Citrix Director has been great. It gives us one pane of glass to be able to monitor what's going on with the user sessions as well as to keep on top of the virtual desktops, any servers that may be offline or behaving suspiciously, or any troublesome spots like disconnections. We also use Citrix Studio for maintaining the actual servers that are hosting these applications. We use it for delivery groups in case we need to modify delivery groups in regards to which groups have access to which applications. It has been very helpful."
"It is a very stable solution."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"The interface and integrated custom applications can be a bit difficult."
"The user interface is not as pretty as it could be."
"I would like them to provide learning tips and a community forum where users can share ideas. They need more detailed support articles on the A10 website."
"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."
"A graphical dashboard for analyzing performance is needed."
"There is two-factor authentication built-in, but it could be more robust."
"Traffic flow issues are very difficult, as there's no means for us to analyze the traffic coming in or out of the appliance without technical support."
"The costs can be quite high."
"It was challenging explaining to customers that it's no longer NetScaler but ADC, and now it's not just ADC but also the rebranding from NetScaler."
"Mastering it requires significant learning and training due to its complexity."
"Manageability and adaptability can also be challenging for end customers."
"An area for improvement would be the difficulty in finding information about standard licensing costs over the internet. They should provide some reference prices on the net to be quickly referred to."
"The tool needs to add a feature where we can access the network policy access manager."
"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."
"Technical support sometimes takes a little longer because of the multilevel ticket priority."
"The WAF component needs to be simplified so that it is easier to use."
