We are moving a high traffic site (20Mb/s - 80Mb/s) to a co-location instead a dedicated server at a hosting company. As part of the infrastructure build-out we are deciding between buying a FortiGate 110C or a capable used 1U Server and installing pfSense on it.
There are obvious cost differences between the latter option but FortiGate seems to be safer solution. Is there anything that I should be taking into consideration when making this decision that might push me one direction or another.
UPDATE 2009/12/23:
I have decided to go with the FortiGate option. I like the idea of pfSense and may try that out later. FortiGate was the safer (and more expensive) choice. However, I have 2 weeks to get this up and going and that seemed to be the smart move considering.
