I'm obviously a fan of the FGTs - I'm aware of the solutions to the "problems" many newcomers experience. I'm comfortable.
But maybe too comfortable. Though I've just introduced my new employer to Fortinet, you must always be objective in your search for proper hardware. Do your homework, cross the T's and dot your I's.
Even when not considering anything other than a FGT, I still consider other vendors - that doubt, nagging or gnawing at the back of my brain. And even when I force myself to be unbiased, the FGT line always wins. I WANT to move on; it's time - I've been with Fortinet for 8 years now. But they somehow keep winning my loyalty. And it's not with unending bugs. The Hardware is legit; it's tight. It's fast. It's pretty - LOOK! They come in WHITE now! How Apple. The point is, FGTs are just doing it and doing it and doing it well. I continue to get creative with design and implementation, and they continue to flex and perform. Unique configurations not possible with other Vendors I've worked with. They have their shortcomings in areas; ALL vendors have their shortcomings - aware or not. But which shortcomings mean nothing to you?
