We've installed Sophos UTM and are running various web sites behind it. Sophos has two options "Form hardening" and "Static URL hardening" that are intended to protect your web site from hackers.
It does this be inspecting the content in a page and, in brief, checking that when the client makes requests from that page that they are valid.
My question is is this type of firewall protection going to become an increasingly common thing that I, as a web developer, am going to have to code around? Or is this always going to be a niche thing that will only work for certain web sites?
I can't find an awful lot of chatter about this topic on the web, so any thoughts would be very welcome.
