The features that I have found most valuable are the SD-WAN and their IP4 policy.
In terms of what could be improved, the SD-WAN is quite difficult, because if you install in the new box, 15 is okay, but if you change from an old configuration, if there is already a configuration and a policy when you change to SD-WAN, you must change the whole policy that you see in the interface.
I have been using Fortinet FortiGate for about two years.
Fortinet FortiGate is stable so far. We had a difficulty, but after we opened the support, we found out that it was only from having the wrong config. But so far, it is stable.
So far our biggest client is only FortiGate 400, a small-medium business.
Their technical support is very helpful, although they only have it for their in-the-box and sometimes we have difficulty with the out of box, with the ISP or other things. So we must find a solution for the customer. But if it is the wrong product or if there is a configuration issue in the product, yes, they're very helpful.
I have also worked with the Hillstone network, with Palo Alto and with Barracuda.
In terms of support, so far FortiGate is helpful whereas with Barracuda I didn't get the support like FortiGate.
The initial setup and new configuration are very easy. It is very user-friendly. It's only three clicks from the menu, two or three sub-menus and we already have it configured. It's not difficult because we have experience with the SonicWall, Palo Alto, etc.., but Fortinet is user-friendly.
In terms of price, FortiGate's price is reasonable. Most of the customers stand by it, and are aware that the price is worth it for the performance.
In terms of advice for anyone looking to use FortiGate, you need to learn about trouble-shooting, because sometimes you find out you have the wrong configuration, not because of a FortiGate problem or FortiGate config, so you are responsible to handle the trouble-shooting.
On a scale of one to ten, I would give Fortinet FortiGate a nine.
One thing they could offer is a version that already has the configuration. This would make it easier. This is something that I would request. I worked with Barracuda, I worked with Palo Alto. If you want it easy. It's very easy. But FortiGate needs to have something more like that, to do it faster.
