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

"Fortinet FortiGate appears to be scalable."
"Fortinet FortiGate has positively impacted our organization by providing stronger network security as it's a next-generation firewall, blocking known threats and vulnerabilities in real-time, detecting and controlling thousands of applications, scanning encrypted traffic, and improving VPN and remote access through automated failover and intelligent routing protocols like BGP over IPsec VPN."
"Fortinet FortiGate is a stable solution."
"The product is easy to install since we only need to follow the user manual, documents, and articles provided by Fortinet to install the product."
"The most valuable features are SD-WAN, application control, IPS control, and FortiSandbox."
"Fortinet FortiGate has a very simple configuration, is easy to set up, and includes SD-WAN features at no additional cost."
"The best features of Fortinet FortiGate are that it does the job effectively and protects our environment."
"I like several features that this product has, such as antivirus and internet navigation inspection. It is also simple to use."
"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 Zyxel Unified Security Gateway solution is stable and does its job effectively."
"This is a capable appliance and the standard features work well for us."
"The most valuable features of the solution stem from web filtering, malware protection, and antivirus."
"The solution can scale well."
 

Cons

"I feel that the reporting needs to be improved."
"I need user-behavior analytics, to find threat scenarios from inside the organization, insider attacks. That would be very helpful for us. In addition, I would like next-generation features for small and medium businesses. These businesses require UTM, all in one product. Fortinet must include it."
"The way everything is set up could be easier. Currently, people need a lot of experience and knowledge to administer it and to link it to devices."
"FortiOS is not simple."
"There were situations of availability related to their switching solutions due to box errors."
"I would like to see improvements with the antivirus and IPS as they are not working properly all the time."
"The pricing of the solution should be more affordable"
"We had a minor problem where there was a major system upgrade on the hardware platfrom and the Mac client was not available as soon as it might have been. The PC client was available immediately, but we had to wait a month or so, before there was a mac client. I was slightly irritated that it was not ready on time, but it was eventually resolved."
"Licensing is not cheap."
"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."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Although manageable, the user interface is a little bit slow and could be improved."
"Sometimes it reboots when you least expect it, and that's the main issue."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"Fortinet costs are 25% lower than the high-cost provider. There is an equipment cost and a recurring monthly cost for licenses and technical support."
"I rate the pricing an eight and a half on a scale of one to ten, where one is low, and ten is high."
"Fortinet FortiGate is expensive."
"The product is expensive. I rate its pricing a six out of ten."
"This is not a cheap solution but it isn't expensive, either. It's a good solution for the right price."
"The cost has increased since the update so I would rate it eight out of ten."
"The price for the Fortinet FortiGate is reasonable. Secure SD-WAN is free of charge. If you have their firewall, it's free of charge. It's very tempting."
"The licensing costs are very low."
"We got a much cheaper price than that provided by Fortinet right now."
"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."
"This gateway is pretty cheap."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
