Known for its load balancing capabilities, the WAF features need to be improved

The solution's initial setup process was easy. For the installation, it takes around five minutes. One person can do the maintenance since it is not required much. So, it's a one-time solution, and its maintenance is fine. The number of people required for maintenance depends on the clients as well. One or two engineers are fine to serve around a hundred clients. If you have a number of devices, more people are needed for their maintenance because of the patching it requires during regular operations. Only for the maintenance, one engineer's fine. However, for regular operations, we need multiple people.

A tool for centralized management including inventory and sales tracking

Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"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."

"For the past two and a half years, we have not had a need to open a tech support ticket. It is really stable. In the past, our experience with tech support was that they were extremely helpful."

"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."

"A lot of our SSL management is done on the front-end side, so there is one pane of glass for a lot of our security certificates. It gives us visibility. It also falls under when certificates are going to expire. Even for servers that are coming down, we can see how that affects the traffic flow by using the services map."

"The DNS application firewall and load balancing are very valuable."

"The solution is stable."

"A10 Networks Thunder ADC is an easy-to-use and flexible solution."

More A10 Networks Thunder ADC pros

"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."

"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."

"From a security standpoint, It is a comprehensive solution in a single box."

"The program is easy to install and to set up."

"Provides resiliency for applications that reside on servers, as well as connectivity to remote applications."

"An essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently."

"Citrix Web App API Protection allows you to enable a blocking mode"

"Enables a Web service that offers persistent client-server connections, IP restriction, URL rewrite (such as remove "/assets/" path from client-side URL path), and cache for CSS or JS files... You can easily use the GUI to set up all these requirements on the same network device within 20-30 minutes. (If you do the same steps on CLI, it might take less time.)"

More NetScaler pros

Cons

"The tool's load-balancing feature should improve."

"The user interface is not as pretty as it could be."

"The interface and integrated custom applications can be a bit difficult."

"Currently, the solution's WAF features are fewer. They should consider increasing their WAF features."

"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."

"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."

"It scaled well for our numbers, up to 3 million subscribers for our most crowded region but I would like to see the same scalability numbers for the virtualized version as well."

"The costs can be quite high."

More A10 Networks Thunder ADC cons

"It can be difficult to setup."

"We face challenges with the solution's firmware upgrades frequently."

"The solution can improve their support and send tickets directly to a Citrix ADC engineer in order to avoid having to escalate each support call."

"We would like to see some fairly large scale improvement in the configuration process for this solution."

"Should offer more flexible cost-effective licensing for small to medium sized organizations."

"The interface needs to be improved because the competition is coming up with ones that are more eye-catching, straightforward, and sophisticated."

"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 licensing model and technical support of the solution could be improved."

More NetScaler cons

Pricing and Cost Advice

"The price of A10 Networks Thunder ADC depends on capacity and the customer's requirement. They have several offerings. They have different price models and options to choose from. Additionally, you need to subscribe to support for the hardware appliances."

"The pricing is fine, considering the features they are providing. If you are an individual user, they'll price the product differently compared to how they price the product that is sold to an organization."

"We previously had F5 and switched because of costs."

"The price of the maintenance support is too expensive."

"It is $7000 per unit for the support annually."

"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."

"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."

"We just pay for support in addition to our licensing."

More A10 Networks Thunder ADC pricing and cost advice

"You get the value for your money. There aren't any hidden fees."

"The tool is cheap."

"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."

"We get value for money. Its price is fair. I don't think it is overpriced."

"It's an expensive product but it works well."

"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."

"The licensing costs for this solution vary depending on which model is being used."

"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."
