If the client had a lot of downtime or a lot of issues with older equipment, or they did not like the fact that they had to pay every year just to be able to use the device, then the return on investment of spending $900 for a Fortinet 60E per site for a three-year contract will hands-down beat pretty much anybody.
It is definitely set it and forget it. There's very little input. You'll save money on consulting. If you were to call me and you're doing Juniper or you're doing Palo Alto, there's a lot more configuring and it's a lot harder to add stuff and therefore, as a consultant, I make more money, and I'm being serious. Once I set up a Fortinet I really don't have to touch it for years.
Maybe I have to log in to check that I need to do an update, however, in that case, they usually send me an email saying hey, your license key is up and maybe you want to buy a new one. I take the old one out and put a new one in, that's when I get paid again. It's boiled down to that.
