Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

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

"The payment function for applications is good."
"The integration with Active Directory is one of the good features, and being able to integrate Active Directory with the firewall is useful."
"Before using this solution, we had many problems accessing our resources because we don't have a lot of internet bandwidth, and by using application control and traffic shaping, we were able to manage users to quickly access services that are important, and this tool has aided in the simplicity of our day-to-day management."
"The solution is user-friendly."
"It's an easy solution to set up."
"We are very well satisfied with the Fortinet technical support."
"It is an excellent product and works extremely well."
"It is one of my favorite solutions to work with, and I would much rather work with it than Cisco Firepower, for example, even though I've got 20 years of Cisco experience with different firewalls, I would much prefer this solution."
"The cost is very low."
"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."
"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

"They are doing good, but they can improve the distributor assignment. The availability of the product and the timeline of delivery are the main things. The distribution should be swift, and the distributor should not reach out to end customers directly. They should work as a distributor. There should also be one more local distributor. Currently, there is only one distributor in Pakistan, and the rest of them are in UAE. It is difficult to work with only one distributor. Sometimes, you don't get along with the same distributor, and that's why they should have one more distributor. Their licensing should also be improved. The activation or renewal of the product should be done from the date of renewal, not from the date on which the license expired."
"Fortinet FortiGate needs to improve the logging and reporting. Additionally, the next-generation application's policies should be improved. When they were released they had bugs."
"The command line is complicated, and the interface could be better."
"The FortiGate reporting system needs to be more detailed about files."
"MTBF: Hardware failure is more common when compared to SonicWall or Cisco ASA."
"They could simplify their deployment process, especially when customers have existing devices."
"The routing capability on the FortiGate devices has room for improvement."
"This product needs to have an analysis feature, rather than having the analysis done through the integration of a different product."
"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 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."
"I have never seen it in any company that I've worked with before, and I would advise other companies not to buy it."
"The product has some scalability and data management issues where improvements are required."
 

Pricing and Cost Advice

"It is a cost-effective solution that meets the user's needs."
"In my opinion, the pricing of the product is reasonable."
"The price of FortiGate is average and I would say that based on the top five products available on the market, it is in the affordable range."
"It's an expensive solution."
"There is a subscription-based model to use Fortinet FortiGate. We pay annually for the solution along with the support. If you want to have all the updates, and security patches you will need to renew your support."
"The beauty is the price performance ratio is great with FortiGate. It provides all the features we needed and the price is comparable with others' firewalls. The price is quite competitive with the firewalls with similar features."
"The product is not very expensive."
"It is more affordable than Check Point and Palo Alto. Another thing is that all the features and the OS remain the same irrespective of the size of the device. Pricing-wise, Fortinet typically provides one-year support with the firewall appliance. There is also an option for three years which is how their licensing works."
"The price of Zyxel Unified Security Gateway is good compared to other similar products in the market."
"This gateway is pretty cheap."

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…
