We look for a couple of things when selecting a vendor or product. First, we look at the user interface and figure out whether it is easy to manage. We also consider the price because we do not want to overpay. That said, price is not our number one priority; user manageability is.
We have been using a pretty wide range of products. We have used models such as the Fortinet FortiGate-30E, 51E, 90D, and 200D. They are all pretty good at doing the job that they are configured for. Obviously, the firewall sizing has to be done right, but if the product sizing is done correctly then they will never go wrong.
I have not yet used the cloud access capability, but we do plan on testing it.
After we purchased FortiGate we grew by forty percent, and it was able to continue to perform as it had before.
Overall it is user-friendly, easy to configure, easy to manage, the support is pretty good, they are priced low, and they do the job that you require.
I would rate this solution nine out of ten.
