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.

Identifying compromised traffic and securing data has been a significant advantage

One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.

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."

"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."

"The solution is stable."

"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."

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

"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."

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

"The ease of use is very good. It's very robust. It just sits and works."

More A10 Networks Thunder ADC pros

"The configuration and integration into the AWS environment was pretty easy."

"BIG-IP LTM's most valuable feature is that it allows you to seamlessly add more servers without impacting your application's configuration."

"We like the capability to combine the content switching with the intrusion prevention and adding the security roles, so we can expose certain sub-pieces outside without exposing everything."

"The most valuable feature is customization."

"I think F5's tech support may be better than Citrix's because they mainly focus on the ADC product, but Citrix support covers Hypervisor, XenMobile, FAS, and ADC. And from my experience, sometimes, we face some issues that Citrix cannot handle."

"The main reason that we suggest this product to our clients is the great integration with other security tools, such as IBM Guardium."

"F5 Big-IP Local Traffic Manager has better modular features especially LTM, which according to the clients, is very beneficial. Most of the users opt for a combination of big IP LTM and WAF which helps them to leverage application load balancing and enhance application security many-fold."

"The most valuable feature is the F5 LTM (Local Traffic Manager). This is the part of the product most organisations will be using most. It provides the core functionality to be able to load balance services and the means and the intelligence to be able to load balance based on advanced logic, e.g., TCL scripting."

Cons

"In my opinion, they need to improve their cloud support. There is support for cloud, but not all functions are there, such as high-availability."

"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."

"There are competitors that have more features."

"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."

"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 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."

"The costs can be quite high."

"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."

More A10 Networks Thunder ADC cons

"One improvement could be updating the user interface (UI)."

"The web interface could be better."

"F5 BIG-IP LTM can improve on the SSL loading which includes the authentication of certificates. Although, most of these issues have been solved there are still some issue that persists."

"It's a very expensive solution."

"An expensive solution for the minimal features we use."

"Initial setup is tricky, if you do not understand the design of this product."

"This is a very expensive solution."

"One area for improvement with F5 BIG-IP LTM could be its pricing, which some may find on the higher side."

Pricing and Cost Advice

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

"The solution costs less than its competitors."

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

"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."

"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."

"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 is good they are very comparative."

More A10 Networks Thunder ADC pricing and cost advice

"Purchasing through the AWS Marketplace was very simple. The main reason that we went this way was the simplicity of buying it there. It is maintained and upgraded for us, and this makes it easy to stay current."

"Compared to using open-source products, the prices are not cheap."

"The licensing model of F5 BIG-IP LTM is highly complex. The operation cost of the solution is high. The overall cost is high."

"The licensing strategy for F5 is good."

"It is quite expensive as a product. Because it is very stable, it is also expensive."

"BIG-IP LTM is considered a premium product, so it's quite expensive and isn't affordable for all customers."

"It is a bit expensive product. Kemp Loadmaster is much cheaper than F5. Its licensing is on a yearly basis. It can be for one year or three years."

"The pricing is inclusive of many features."
