I am in need of a Intrusion Detection Software solution for a 64-bit Windows 2008 server. It is a very critical aspect of a project I'm working on and they will not accept the free Snort solution. They want a proprietary solution for Intrusion Detection, which I think is ridiculous but thats what the client wants. Does anyone know of any reasonably priced software solution that supports a 64-bit Windows 2008?? I need this ASAP, just want to put this project to bed.
