I am using Fortinet FortiGate as a firewall.
The most valuable features of Fortinet FortiGate are remote access, web filtering, and IPS.
Fortinet FortiGate could improve by having more capabilities for troubleshooting VPN connections. For example, I do get some feedback about the current status, but I could use some history and logging of important events. The information is logged in our Syslog server, but I could use that information from the device. If they could provide a GUI to have some more insight on what's going with my VPN would be useful.
The way Fortinet FortiGate handles the phase two connection of a VPN setup could be better. For example, if I have to make a phase two traffic selector input, I cannot add more ports. For example, on a specific IP address pair, if I have an IP address pair source and destination, then I can only add one port. I'm not sure if I can do that through the command line, but on the GUI, I cannot, and this is a problem. I have to select another IP address pair to allow another port and this means new traffic selectors and a new set of tunnels. This causes more tunnels to need troubleshooting.
I would like to be able to pass more diverse information through the same tunnel, and it doesn't seem to be possible if you want to limit the traffic through the tunnel and not allow all protocols between the same IP address pair. If we want to limit the ports, then I find there is a problem.
I have been using Fortinet FortiGate for approximately a year and a half.
We have a contract with a Fortinet partner, and they're very good at providing support. We don't have the communication directly with Fortinet.
I have previously used a Cisco firewall, the 5520 model. It was not a next-generation firewall and did not have IPS integrated, and it was quite difficult to manage and to find features and implement them. Fortinet FortiGate is very good at this.
The initial setup of Fortinet FortiGate is straightforward.
I do not have first-hand experience with the rice of Fortinet FortiGate, but I have heard the price was reasonable.
I rate Fortinet FortiGate a ten out of ten.
