title: is there any Web Application Firewall for asp.net?
body: <p>I want to hardening my website against simple dos/xss/sqli/etc...
  but I don't want to delve into security programming for now so I want to use a ready made class or library something like "mod_security" in linux.</p>
  
  <p>about a year ago I'd found a project like modsec for asp.net but right now in google I've searched too much but nothing interesting.</p>
  
  <p>anyone knows anything about WAF in .net ?</p>
  
  <p>regards.</p>
