Re: Application Firewall

[Adriel Desautels <adriel () netragard com>]

Honestly,
	Apache with mod_security setup as a reverse proxy is quite good. I've 
used that particular configuration in many instances and I have no 
complaints what so ever. You can build it yourself, or you can get an 
appliance from the ModSecurity folks. I HIGHLY recommend this solution.
