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.

Is stable and has a user-friendly dashboard and a good interface
We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good We cannot secure a specific IP class with this firewall. Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the…

User has benefited from stable performance and effective completion of security tasks
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…

Quotes from Members

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

Pros

"Two aspects I'm happy with regarding Fortinet FortiGate firewall are the easy user interface and its resilience during power interruptions."
"Previously, we were using another firewall device, Sophos. Compared to that, Fortinet FortiGate provides more features and better security."
"It has the same functionalities throughout the range of products."
"The dynamic segmentation feature in Fortinet FortiGate is pretty good."
"It has improved our security capabilities."
"It's a firewall that secures our internal network. I have been using it since 2013, and I find that most of the features are advanced, and very user friendly."
"It performs very well."
"Initial setup is easy to configure."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"It has been stable so far."
"The solution can scale well."
"The Zyxel Unified Security Gateway solution is stable and does its job effectively."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"This is a capable appliance and the standard features work well for us."
 

Cons

"Fortinet FortiGate could improve their documentation on forward error correction and failover technologies."
"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."
"They can add automation for monitoring and policy optimization on the firewall. I think using AI to do some optimization on the policies would be beneficial, such as providing alerts about policies that haven't been used for a long time or identifying overlapping policies."
"FortiGate should have a better way of detecting and managing the system memory because otherwise if the memory is too low, a system restart is required."
"The solution is not scalable."
"Its price could be better."
"I think Fortinet FortiGate is stable because previously it had a hiccup around a bug within the authentication VPN due to the firmware, but after updating, it's easier to control."
"Two-way inspections are not possible in FortiGate."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"Licensing is not cheap."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Sometimes it reboots when you least expect it, and that's the main issue."
"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."
 

Pricing and Cost Advice

"Setup cost may be not so low, as you expect, because it depends on different factors, but TCO for 5 years may pleasantly surprise you."
"The Fortinet FortiGate security features cost approximately $1,500 a year. The firewall itself doesn't have a recurring cost. It's the security features on top of that that you pay for."
"It's a year based license."
"It could be more competitive and cost-effective."
"It is not the cheapest one, but its price is very competitive."
"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"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."
"The license of Fortinet FortiGate should be reduced."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"We got a much cheaper price than that provided by Fortinet right now."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
