A stable solution with an intuitive interface and quick customer service
I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

I use it mostly for VPN and for some firewall solutions When considering my main use case with VPN, I can say that I got the Zyxel Unified Security Gateway, and it works fine. However, we are thinking about using a different solution based on open source because Zyxel Unified Security Gateway…

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

Cons

"The stability could be a bit better."
"We have experienced a number of failures when trying to upgrade firmware and the process takes a long time."
"Regarding stability, I have experienced performance issues with Fortinet FortiGate. Sometimes it does not work correctly in certain situations, such as DNS or URL categories, where it might block incorrectly."
"The only problem that we have here in China is that the whole subscription process on Fortinet is a little bit difficult if you are doing it from China."
"Fortinet FortiGate could improve by having more capabilities for troubleshooting VPN connections. For example, I do get some feedback about the current status, but I could use some history and logging of important events. The information is logged in our Syslog server, but I could use that information from the device. If they could provide a GUI to have some more insight on what's going with my VPN would be useful."
"I think that the infrastructure for the VPN could be improved. The way that it is bundled also made it difficult to use and sell as it is too expensive."
"One of the weaknesses of the solution is something we noticed, especially after comparing the tool with SD-WAN features, since, unfortunately, in a massive scale size environment, the solution is not good. I"
"Fortinet FortiGate could improve the user interface. There should be more functionality and options through the GUI."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"Although manageable, the user interface is a little bit slow and could be improved. The advanced UI allows me to do whatever I want, but this is where the issue of speed exists."
"Although manageable, the user interface is a little bit slow and could be improved."
"The product has some scalability and data management issues where improvements are required."
"Sometimes it reboots when you least expect it, and that's the main issue."
 

Pricing and Cost Advice

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."
"The price of Fortinet FortiGate is the lowest in the market."
"It's expensive, but compared to the competition it's okay."
"Work through partners for the best pricing."
"When you look at these end security systems and firewalls, these firewalls even five years ago were $50,000 or perhaps $25,000 to implement in some types of customer sites. Now we're talking about tools that are $1,000. In this case, it might have been $500 or something like that."
"We pay for the solution annually."
"​We saved a bundle by not needing all the past appliances from an NGFW.​"
"It's an expensive solution"
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."

Sophos UTM vs. Fortinet FortiGate
I have used both Sophos and Fortinet products in production and I have found the Sophos UTM appliances (hardware and virtual) to be a better fit most of the time -- with a few caveats which I will touch on below. In both instances, the transition from TMG will be mostly straightforward. The main…
