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.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

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."
"The most valuable feature is the SSL offloading capacity; it is easy to manage and easy to configure."
"TSL and SSL offloading are both very 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."
"Fortinet FortiADC is a good product because each and every piece of content is monitored by it."
"The main feature that we use is GSLB (Global Server Load Balancing). GSLB makes the customer's network more reliable by scaling applications across multiple datacenters. GSLB as a disaster recovery solution can direct traffic based on site availability."
"The most valuable features would be content caching and content compression; it also has an inbuilt firewall and a web application firewall feature, which I doubt any other ADC supports."
"Overall, FortiADC is a good product, although it is complex to configure."
"Packet inspection has been effective for mitigating DDoS attacks."
"It allows me to see all the traffic on my network."
"The product's initial setup phase was really easy."
"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."
"We've been completely satisfied with the product."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The protection resources and the support are valuable features of the solution."
"The solution is very user-friendly and very easy to use."
 

Cons

"It would be good if they built in a fully functional web application firewall."
"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."
"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."
"My main complaint is that the WAP functionality is very primitive."
"The product’s price could be reduced. Also, some of its features need to be more advanced."
"The configuration is relatively complex."
"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 challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The product’s pricing needs improvement."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The solution can be a little more user-friendly and it can be more affordable."
"Earlier versions of firmware had bugs that limit my options."
"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."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
 

Pricing and Cost Advice

"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"The solution could be more cost-effective."
"The product has average pricing. I rate its pricing a five out of ten."
"They offer a perpetual license."
"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 solution's pricing is an issue and should be improved."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
