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.

Saeid Khanipour Ghobani

IT Manager at Technology Evaluation Center

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

"A10 explained why the latency dropped significantly on a site that we have."

"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."

"It's a very friendly solution, easy to configure and it's very flexible."

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

"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 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."

More A10 Networks Thunder ADC pros

"Fortinet FortiADC is a good product because each and every piece of content is monitored by it."

"The product has flexible and interesting licensing options."

"Ease of use in deploying and having it up and running requires minimal knowledge."

"From a technical perspective, it is the most scalable device from Fortinet."

"I am impressed with the product's load-balancing feature."

"This ensures that clients can connect to their applications without interruption."

"The GSLB, the DR side, is the best part. Because we had our main side in one city, we created another, and we had a complete MPLS over the internet. We used the GSLB and data loss for our business applications."

"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."

More Fortinet FortiADC pros

Cons

"The user interface is not as pretty as it could be."

"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."

"We are starting to do a lot with containers and how the solution hooks into Kubernetes that we haven't explored. I'm hoping that they have a lot of hooks into Kubernetes. That would be the part for improvement: Marketing use cases with containers."

"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 costs can be quite high."

"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."

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

More A10 Networks Thunder ADC cons

"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."

"Issues with SSL and encrypted traffic."

"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."

"Though FortiADC is useful, I'd appreciate more user-friendly features and in-depth insights into network activity, like detailed logs and AI-driven feedback for optimization."

"Because it is so generic, the documentation requires special attention. A person who has not worked on Fortinet FortiADC or a similar product will struggle to understand what the document is trying to say. The documentation could be more specific, and more detailed."

"The configuration is relatively complex."

"It would be good if they built in a fully functional web application firewall."

"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."

More Fortinet FortiADC cons

Pricing and Cost Advice

"We just pay for support in addition to our licensing."

"The solution costs less than its competitors."

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

"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."

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

"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."

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

More A10 Networks Thunder ADC pricing and cost advice

"The price is competitive"

"Compared to F5, FortiADC pricing is better."

"They offer a perpetual license."

"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."

"I believe the price is good. It's fair. There are no extra costs."

"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."

"The solution's pricing is an issue and should be improved."

"The solution could be more cost-effective."
