Has supported load balancing for medical applications and could benefit from more custom configuration options

Some customers need custom management for handling their applications across the servers. Instead of having a predefined solution, if we had space for custom-based algorithms to load balance the traffic, it would be better. We have faced such cases with A10, where we can leverage many custom scripts and do much more. Even though A10 primarily focuses on SMBs, they have also ventured into the enterprise market. Fortinet has been a pioneer for enterprise solutions, such as firewalls, SASE, ZTNA, and SD-WAN solutions, and they are in a leader quadrant. Therefore, they should have more options. From a pricing perspective, it is expensive.

An easy-to-use tool with great GUI

The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"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 product has flexible and interesting licensing options."

"The most valuable feature is its simplicity."

"It helps with defining server load balancing tasks and managing SSL certificates, ensuring the communication flow through the Fortinet gateway."

"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."

"Key features include SSL Offloading, VM availability, and L7 load balancing."

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

"Ultimately, Fortinet constructs every solution needed for each defense layer, making it comparatively better than Trellix, Trend Micro, or SentinelOne."

More Fortinet FortiADC pros

"The solution is very user-friendly and very easy to use."

"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."

"The product's initial setup phase was really easy."

"It allows me to see all the traffic on my network."

"The equipment works very well, and I have not encountered any issues with it."

"The protection resources and the support are valuable features of the solution."

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."

"We have researched them all, and it's a good solution all around."

More Fortinet FortiDDoS pros

Cons

"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."

"I think it would be helpful if Fortinet put more video examples on their cookbook site."

"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."

"The solution’s pricing could be improved."

"Some customers need custom management for handling their applications across the servers. Instead of having a predefined solution, if we had space for custom-based algorithms to load balance the traffic, it would be better."

"FortiADC is complex to configure so the interface should be improved."

"The solution should improve finding false positives and false negatives. There are a lot of false positives."

"Fortinet FortiADC should include an advanced-level SD-WAN."

More Fortinet FortiADC cons

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."

"The solution can be a little more user-friendly and it can be more affordable."

"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."

"The product’s pricing needs improvement."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"The web interface could be much better."

"I find that there have been issues in the past year with the solution hanging. It freezes often."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."

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

"Compared to F5, FortiADC pricing is better."

"The product has affordable pricing."

"The price is competitive"

"They offer a perpetual license."

"The product has average pricing. I rate its pricing a five out of ten."

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

"The solution is reasonably priced."

"It's quite pricey."

"The product’s pricing needs improvement."

Questions from the Community

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.
