We are strictly a government entity. We are a customer.
The model that we are using is the 500E, which is for small and medium enterprises. We are not a big institution. We do not have the latest version. We like to wait about three months before we apply anything new to make sure the early releases aren't flawed. After three months, after we've got a good review, then we will say, "Okay, let's upgrade to that version."
Even though we feel that sometimes they create a new version to take care of a vulnerability or threat, we like to be safe and avoid bugs. The version that we are fitting currently is 6.4.2, which is fairly stable.
Apart from the fact that they should just include everything in their offering, everything else works fine for me. There's a whole lot of Fortinet products that work together, FortiSwitches, FortiAP's, etc. Overall, I would give it eight of ten.
