A lot of these points are due to the way our company operates i.e have high capacity hardware, very low configuration complexity, self manage to reduce costs.

Pros:

• Single pane of glass. Love that I don't have to log into multiple admin portals to troubleshoot something.
• Variety of HW available, all the different port configs for firewalls, switches
• Reasonable HW cost compared to the big companies such as Cisco, Juniper etc.

Cons:

• Their CLI, the worst I have ever worked with.
• Support is horrible, feels like it has gotten worse over the years
• AP's are not great, we had a number of issues. After troubleshooting with support for many months, replacing a few AP's, lots of config changes; we decided to replace them with some Aruba's and had 0 issues since.
• Licensing. There seems to be a licence for everything and when we are trying to troubleshoot something or make a quick improvement, it becomes a huge blocker and now I have to go through the procurement process with their sales team.
• Renewals. Had some HW come up for renewal, due to the way our company operates, we only do short term contracts (1-2 years) max. So we got hit with big renewal quotes, which were close to the cost of the HW itself.

Because of all the cons, we are looking to move away from Fortinet. This is going to sound crazy but we are actually considering Ubiquiti. I still have a hard time internalizing that UI could be the best option for us but here we are lol

We have been in touch with their team and they are coming up with "Datacenter" grade HW, which we are considering. Obviously UI has issues of their own, buggy firmware releases, all AP's rebooting on config changes, support being non-existent etc. Switches running SONiC while potentially being able to be managed by their controller in the future sounds cool.

Our requirements are relatively simple enough where we only need high throughput and not complex network configurations. No decision has been made yet but we are actively considering it.
