Vice President at a computer software company with 1,001-5,000 employees

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 highly stable and scalable load-balancing software that offers great technical support

My company is really happy with Kemp LoadMaster as a product. My company is also happy with the support we receive from Kemp LoadMaster. I want Kemp LoadMaster to provide users with better reporting capabilities in relation to TCP packets. In general, the connections that are present in the system require improvement. Feature-wise, Kemp LoadMaster has everything that our company's customers require. Kemp LoadMaster also has features that have supported our company's past projects.

Quotes from Members

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

Pros

"It helps with the efficiency of application deployments and data security."

"Feature-wise, A10 Networks Thunder ADC is better for troubleshooting...Stability-wise, I rate the solution a nine out of ten."

"The Global Server Load Balancing (GSLB) is simple to use."

"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."

"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."

"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."

"The solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."

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

More A10 Networks Thunder ADC pros

"The DNS Load Balancer makes it so that I don't have to worry about site failures."

"I like that this is a Network Load Balancer that can be used practically with any application in the backend. They have how-to guides on how to set up Kemp NLB with Exchange, but you can use it as well for Sharepoint, RDS, or any other back end server."

"Great web balancing and remote access balancing."

"The most valuable feature so far has been the high-availability options that allowed us to add an additional Kemp LoadMaster VLM virtual appliance into our VMware vSphere environment, to provide failover for our existing LoadMaster."

"The feature that allows us to easily disconnect a server when we need and bring back online is the most valuable. It's a click of a button. This allows us to keep all systems up. We can then run updates, perform reboots whatever we need to one of the servers without taking production down."

"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."

"The configuration is really easy and the web portal is self-explanatory."

"It helps with efficiency and reactivity, in case of assistance needs."

More Kemp LoadMaster pros

Cons

"A graphical dashboard for analyzing performance is needed."

"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."

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

"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 solution should add automation features in the next release."

"The costs can be quite high."

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

More A10 Networks Thunder ADC cons

"It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."

"The GUI is rather technical and complex, so it could be improved by making it simpler and more user-friendly."

"They were still in the process of development, and for example, we set it up in a cluster. So it was one logistical unit built out of two physical devices. And the expected behavior, which I know from other devices, will be formed into a logic cluster. It's that you configure one unit. Then you bring the second unit into this cluster with the already configured primary unit. So the secondary box pulls all the configured ones from its neighbor, does everything automatically, and then synchronizes with this primary neighbor. And then it works, like, one logical unit. And this didn't work with the Kemp's initially, where they caused a lot of issues when building up a cluster, so there were some specials on how to set this up. When we built or set them up for the first time and the months afterward with no new software releases, there were a couple of problems, but in the end, they worked fine. So, they developed a lot and learned from what they've responded to, what we responded to them, and what needs fixing."

"In my opinion, the layer seven loads balancing that we're mainly using for web servers, doesn't seem to pick up when there are issues at the application level."

"I want to have the ability to pull a particular server. The DevOps portion was challenging for me, like if I needed to redirect from one IP to another URL. I needed to look that up, and the knowledge base is not well organized. When I look for information about Kemp on the Internet, I don't find many articles or something like that."

"There are some challenges with updates on certain models that don't have a few features."

"If you want logging for SMTP traffic, you have to enable ESP, which requires you to define allowed IP addresses. That’s irritating, to say the least."

"So far, the only hitch we have run into is that would have been nice to have an easier method to add allow/whitelist entries into the Access Control lists for virtual services."

More Kemp LoadMaster cons

Pricing and Cost Advice

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

"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."

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

"You get a lot more for your dollar with A10."

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

"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."

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

"The pricing is a third of the price of the F5 competition."

More A10 Networks Thunder ADC pricing and cost advice

"This product has good value and features for the money."

"The Kemp LoadMaster is a tremendous value."

"It has a great price for the solution they offer."

"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."

"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."

"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."

"The license varies according to the number of megabits."

"Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."
