Find out what your peers are saying about A10 Networks Thunder ADC vs. Citrix NetScaler ADC and other solutions. Updated: January 2020.
397,717 professionals have used our research since 2012.
We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Compared to F5, which I used about six years ago, the A10 is much easier when routing. You don't have to use the wildcard bits to route it between the different segments. It's much less troublesome to configure.
The ease of use is very good. It's very robust. It just sits and works.
A10 explained why the latency dropped significantly on a site that we have.
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.
We do have the option of creating virtual chassis, so that gives it a bit more security. If we find an application which is not going to play well in the main pool, we can easily create a virtual chassis and have that application in that virtual chassis. With the virtual chassis we can also create system partitions and have a test system for test applications, and have the others elsewhere.
The Global Server Load Balancing (GSLB) is simple to use.
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 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.
Helped us a lot with load balancing.
For desktop application management, I recommend the NetScaler edition. This product is like a Swiss army knife. Citrix NetScaler ADC supports the education front-end.
I can turn on features without actually owning a license. I can test them out, I can use them for a while, and then I can be licensed up. That's awesome. I don't have to have a license immediately before I can start to deploy things rapidly, rapid deployment is a plus.
It has helped us to increase the resiliency of the application and the performance.
It is the best product out there.
Scalability is great. One of the best features of NetScaler is that it can scale out.
This solution allows the user to easily scale out application delivery, and provides secure remote access.
There is room for improvement in the GUI. I just migrated from the 2.7 software train to the 4.1, and there are still people on 2.7. The latter is a very old GUI if you compare it to F5. It's not as easy to use and a lot of things are missing. They've made a lot of improvements in the 4.1 step, but compared to the ease of use of F5, it's still quite difficult. For people who haven't got a lot of experience, the GUI can be quite challenging.
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.
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 solution does logging, but the logging capacity is really small. Because we have a bunch of traffic here, we usually get a logging-side warning that "This many logs were lost because of the heavy traffic." If the logging was better, that would be very good.
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.
When it comes to support, there is always room for improvement. First call resolution is not always there for urgent issues. The first call resolution is something that could be improved upon.
They need to make the user interface (GUI) a bit more usable and intuitive. Some features can be a little difficult to find at times. Sometimes, the workflow in the GUI doesn't match the workflow of an actual workflow. E.g., if I want to create a load balancer application, sometimes you've got to do things a bit out of order in the GUI in order to make it work right.
The setup depends on certain situations. In certain scenarios, it may be more complex than others. For example, while the initial configuration may be easy, the environment itself may be complex and that may limit the ease of deployment. It is easy for those who understand their environment.
Technical support sometimes takes a little longer because of the multilevel ticket priority.
Does not include security. A web application firewall would be a nice addition.
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.
I would like to see them make it easier to do some of the more complex things. For example, a web re-direct requires two pieces to it. You have two ports and when people want to go to a web page, they just type in the webpage that on the backend it will redirect them to a secure link. The initial setup of that is cumbersome because you have to do it twice. There are things that can be replicated. The IP address, for example, is the same. This change would go a long way. Don't make me do it twice and don't make me have to read tons of documentation to figure out how to do it. Ease of configuration for some of the more complex processes would be a good improvement.
The technical support has room for improvement.
It can be difficult to setup.
I would like to see more integration for single sign-on.
Should offer more flexible cost-effective licensing for small to medium sized organizations.
Pricing and Cost Advice
As for the initial investment in the hardware, F5 and A10 are quite similar now. For the current A10 solution, the initial cost was about $36,000. As for annual support, the F5 solution would be between $10,000 and $12,000, while the A10 is $2,200 a year for support.
There were budgetary constraints that keep us from investing in the single pane of glass traffic management feature. We saw a demo of this feature about a year to a year and a half ago.
It is $7000 per unit for the support annually.
We previously had F5 and switched because of costs.
One of the main reasons for switching away from Cisco was the licensing model. A10 gives you global server load balancing for free, while Cisco charged a significant licensing fee for that.
For the hardware and license, we paid $35,000 per box, which was a one-time cost. Then, for the Gold Support on the two boxes, we pay $9400 annually.
The pricing is a third of the price of the F5 competition.
We have a yearly licencing fee, and there are no additional costs.
Ninety day free trial makes it easy to try out this solution.
Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much.
NetScaler does the same thing as an F5 and it's cheaper.
You get the value for your money. There aren't any hidden fees.
I do not have any experience with the pricing of the product.
We are quite happy with price. It's not too high.
We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.
