Single-pane management has simplified firewall control and has improved risk mitigation
I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.

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.

Cons

"Having used the FortiOS for a period, the improvement of functions and additions have been both "Great" and "Poor," as one gets used to using a product, menu and layout changes can be a bit confusing at first, however you slowly start to get more familiar over time."
"Fortinet FortiOS can improve the GUI and remove the command line interface. All the functionality should be available from the GUI. Day-to-day management can be tough for IT administrators. Additionally, the reporting is not very good."
"It could more scalable for the lower end users."
"FortiOS could provide a more detailed analysis of the network and connected devices."
"The reporting for this solution could be improved. It could also be more stable and offer better pricing."
"There is no flexibility."
"Right now, it's very trendy to integrate everything into the cloud. This solution would be more effective if they did more integration in that regard."
"A switch should be introduced."
"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."
"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."
"The tool only had some memory-related problems."
"The room for improvement would be the SSL VPN license cost."
"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."
"Having frequent live webinars on a monthly basis would really help."
"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."
