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.

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

"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."

"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 solution is flexible."

"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."

"We can control access based on the specific application. If other devices are attempting to directly access the servers, you can block them. Additionally, you can balance the load among servers to optimize performance. For example, utilizing caching can make the application run faster."

"The Deterministic CGNAT feature is valuable for us."

"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 most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."

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."

"One of its most valuable features is fundamental load balancing, supporting both basic load balancing and database teams."

"The advantage of Citrix Web App and API Protection is just its graphic user interface for beginners. The solution is nothing special, but we have to use it for the corporation. Another advantage of Citrix Web App and API Protection is that we have our copy to test things and get the know-how of it."

"One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low."

"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."

"The most valuable features are the VDA Delivery, Gateway Fort, and the load balancing."

"Helped us a lot with load balancing."

"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."

More NetScaler pros

Cons

"The product is expensive."

"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."

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

"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."

"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 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."

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

"We are starting to do a lot with containers and how the solution hooks into Kubernetes that we haven't explored. I'm hoping that they have a lot of hooks into Kubernetes. That would be the part for improvement: Marketing use cases with containers."

More A10 Networks Thunder ADC cons

"The solution's pricing is a big concern and should be improved."

"Mastering it requires significant learning and training due to its complexity."

"Citrix is more expensive than Horizon."

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

"The security is okay, but the monitoring and reporting need improvement."

"The product could be improved by making it easier to use and easier to implement."

"I think the documentation should be improved."

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

Pricing and Cost Advice

"The solution costs less than its competitors."

"We did try out the solution’s Harmony analytics and visibility controller for its one-year trial. Due to the cost, we chose not to keep it onsite."

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

"Pricing is one of the features of the product that influence customers to use the product."

"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."

"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."

"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."

"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."

More A10 Networks Thunder ADC pricing and cost advice

"It's not for startups or SOHO."

"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."

"After deployment, Citrix Netscaler shifted to a subscription-based license scheme for support, which is slightly more expensive."

"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."

"The solution is undoubtedly very good, but it is expensive."

"This product is more expensive than some of the competitors."

"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
