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.

Quotes from Members

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

Pros

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

"The Deterministic CGNAT feature is valuable for us."

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

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

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

"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."

More A10 Networks Thunder ADC pros

"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."

"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."

"The price is very good, and it's not very expensive."

"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."

"The solution is simple and powerful. I find the Barracuda Load Balancer ADC's load balancing function most valuable. It balances the traffic well. The security features, like the Web Application Firewall, are also very helpful."

Cons

"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."

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

"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 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."

"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."

"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 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."

More A10 Networks Thunder ADC cons

"The Barracuda Load Balancer ADC could be improved with more customization features. For example, F5 uses iRules for custom configurations. I haven't found something similar in Barracuda yet. The load balancer and WAF's basic and common features are enough, but we need more customization options."

"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."

"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."

"The quality of the solution's performance could be improved."

"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."

Pricing and Cost Advice

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

"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."

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

"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."

"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."

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

"The solution costs less than its competitors."

"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."

More A10 Networks Thunder ADC pricing and cost advice

"I rate the solution's pricing a five out of ten."

"Load Balancer ADC is cost-effective and is about half the price of F5."
