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.

Offers good features like URL filtering, IPS, and IDS to users
We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

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…

Cons

"Fortinet FortiGate firewall is good, but other products like the switching part and all that fabric, in handling very audio-video traffic, sometimes it struggles on the switching part, but on the routing part, it is fine."
"Other providers, such as Palo Alto, are ahead in terms of safe functionality. So, for me, delivering truly safe service is probably something that still needs to be improved."
"In FortiGate Next Generation Firewall (NGFW), my concern regarding improvements is the licensing model."
"The SD-WAN functionality is a bit overly complicated and not fully documented."
"Fortinet FortiGate is not very easy to use. The navigation could be improved to make it easier to use."
"Being a great product, some changes in the pricing would make it a great choice for even more organizations."
"Application management can be improved."
"It should be more stable."
"The tool needs to improve its price."
"The current usage reporting is very basic. I would like to be able to access more granular data."
"SSL VPN license cost is not cheap."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"The tool only had some memory-related problems."
"The room for improvement would be the SSL VPN license cost."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"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."
"Sometimes it reboots when you least expect it, and that's the main issue."
"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."

"We just pay a flat monthly fee to the vendor for the support."

"The product pricing is reasonable."
"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."
"Hillstone's pricing is economical and neither very high nor very low."
"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."
