I am currently working on a project which will be using IIS as it's main web server facing the internet. I was hoping to use something like a Web Application Firewall to increase the security stance of IIS. I am hoping that someone can provide some guidance on which to use and for what reasons.

The two solutions I was looking at was webknights and urlscan, but other options are welcome.

This question came from our site for pro webmasters.

urlscan is simple and supported by MS!

Can you consider it a Web Application Firewall like webknights claims to be? How configurable is it? – CtrlDot Jun 21 '11 at 20:02
sorry I have no idea exactly what webknights does can't find any reference to it on google. Also I would not call urlscan a web app filter. – tony roth Jun 21 '11 at 23:53
