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.

Quotes from Members

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

Pros

"The solution provides high-level services such as availability, redundancy, and load balancing between servers."
"Fortinet FortiADC is a stable product."
"FortiADC helps application availability and improves user-response time, and in addition, the price is competitive."
"Ease of use in deploying and having it up and running requires minimal knowledge."
"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."
"My experience with Fortinet has been very positive."
"Content caching and content compression are good features."
"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."
"The solution is very user-friendly and very easy to use."
"It allows me to see all the traffic on my network."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The product allows the users to adjust the thresholds."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
 

Cons

"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."
"Fortinet has some drawbacks, and it can be a bit challenging to scale."
"Fortinet specifies that the solution can be used for 1,000 clients, but actually we've found that you can't go above 400 for content compression and rewriting."
"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."
"The initial setup was not complex, but it was not simple either."
"The initial setup could be simplified."
"The user interface could be more friendly and CLI could be more like that of Fortigate."
"It would be good if they built in a fully functional web application firewall."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"Alerts and reporting features must be improved."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"Earlier versions of firmware had bugs that limit my options."
