SatishBabu - PeerSpot reviewer
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.

High-level load balancing and routing protocols but scalability is limited to 200 gigabits
The initial setup and configuration are very easy because the solution includes a simple OS. Initial configuration takes about ten minutes for simple environments. It is important to assess the environment and decide what services, servers, and web applications are needed. The solution can be configured in router mode or one-arm mode which uses source NAT as destination NAT to send traffic to the firewall. One-arm mode is more complex and requires discussions with our engineers. For example, you have a website with Node.js for your programming language, Amazon S3 for your CDN, NGINX for your web server, and you use both React and reCAPTCHA. Our team meets with your developer to learn your website and OS through a multi-step process and then we configure the solution to protect everything.

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 stable."
"The Deterministic CGNAT feature is valuable for us."
"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."
"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."
"The ease of use is very good. It's very robust. It just sits and works."
"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."
"From a technical perspective, it is the most scalable device from Fortinet."
"It's a good product because it supports all the features that ADC solutions in the market can support, like F5 solutions, for example, such as the LTM of F5."
"Although FortiADC has multiple features that I like, the global DNS is the most helpful. It is primarily useful for customers with huge environments and at least two data centers. FortiADC can act as your DNS server. It can check which data center has the lowest latency, and route traffic to that one. It's an intelligent DNS."
"Because ADC is the intermediary between the servers and the end-user application, it gives thorough information about the traffic, what the problem is."
"The most valuable feature is the SSL offloading capacity."
"Simple to use and easy to integrate."
"I am impressed with the product's load-balancing feature."
"The solution enhances performance by efficiently balancing the load across multiple backend servers."
 

Cons

"The solution should add automation features in the next release."
"The interface and integrated custom applications can be a bit difficult."
"There are competitors that have more features."
"There is room for improvement in the GUI. I just migrated from the 2.7 software train to the 4.1, and there are still people on 2.7. The latter is a very old GUI if you compare it to F5. It's not as easy to use and a lot of things are missing. They've made a lot of improvements in the 4.1 step, but compared to the ease of use of F5, it's still quite difficult. For people who haven't got a lot of experience, the GUI can be quite challenging."
"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."
"There is room for improvement in the upgrading process. Sometimes we have to contact A10 for verification of some stuff."
"The tool's load-balancing feature should improve."
"A graphical dashboard for analyzing performance is needed."
"Issues with SSL and encrypted traffic."
"It would be good if they built in a fully functional web application firewall."
"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"FortiADC is complex to configure so the interface should be improved."
"The product's stability for VMs could be better."
"The product’s price could be reduced. Also, some of its features need to be more advanced."
"The L7 Persistent load-balancing algorithm has not worked for me after having tested it many times with my customer's in-house application. I'd like to suggest that the company make sure that all load-balancing algorithms work properly with most applications, even those that are in-house apps."
"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."
 

Pricing and Cost Advice

"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."
"You get a lot more for your dollar with A10."
"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."
"The price of the maintenance support is too expensive."
"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 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."
"It is $7000 per unit for the support annually."
"The pricing is a third of the price of the F5 competition."
"The solution could be more cost-effective."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"Compared to F5, FortiADC pricing is better."
"They offer a perpetual license."
"The product has affordable pricing."
"I believe the price is good. It's fair. There are no extra costs."
"The solution's pricing is an issue and should be improved."
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
