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

"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."
"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 solution is user-friendly and the CLA troubleshooting is easier compared to other solutions."
"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."
"The DNS application firewall and load balancing are very valuable."
"The most valuable features in A10 Networks Thunder ADC are the ease of configuration, user-friendliness, and simplicity to sell to customers."
"The solution is flexible."
"The most valuable feature is its simplicity."
"The most valuable feature is the SSL offloading capacity."
"The solution provides high-level services such as availability, redundancy, and load balancing between servers."
"The user interface is very easy and integrates with Sandbox easily."
"I use load balancing technology like Round Robin or low weight to maintain session-based connections. This ensures that clients can connect to their applications without interruption."
"Customer service is excellent."
"Because ADC is the intermediary between the servers and the end-user application, it gives thorough information about the traffic, what the problem is."
"TSL and SSL offloading are both very good features."
 

Cons

"A graphical dashboard for analyzing performance is needed."
"When it comes to support, there is always room for improvement. First call resolution is not always there for urgent issues. The first call resolution is something that could be improved upon."
"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."
"There are competitors that have more features."
"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 solution should add automation features in the next release."
"There is two-factor authentication built-in, but it could be more robust."
"The user interface is not as pretty as it could be."
"The solution needs to integrate sFlow. sFlow provides better visualization of the bandwidth and types of traffic passing through the device. When used in the traffic path, this information can be really useful."
"I will queue all the details clearly on the ticket, including the diagram, log files, and everything else. Once a case is assigned, they ask the same questions again without checking the submitted details."
"The initial setup could be simplified."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"It would be good if they built in a fully functional web application firewall."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"Fortinet FortiADC should include an advanced-level SD-WAN."
"One of the product's areas of improvement includes reducing the number of components requiring additional licenses, such as antivirus and IDS, which are already covered by our firewall."
 

Pricing and Cost Advice

"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."
"You get a lot more for your dollar with A10."
"We previously had F5 and switched because of costs."
"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 just pay for support in addition to our licensing."
"The price of the maintenance support is too expensive."
"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 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."
"The product has affordable pricing."
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"I believe the price is good. It's fair. There are no extra costs."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"The product has average pricing. I rate its pricing a five out of ten."
"They offer a perpetual license."
"The price is competitive"
"The solution's pricing is an issue and should be improved."
