PCI Compliance: File Integrity Checkers [closed]

We're looking for a file integrity checker for our windows server environment. Anyone have any good suggestions?


I've seen Tripwire highly recommended on UNIX platforms; I believe there is a Windows version as well, might be a starting point.


Another option is Verisys. Like Tripwire it does file integrity monitoring and has a central administration console for reporting etc, but it's a whole lot easier to use than the commercial versions of Tripwire, and cheaper too :)
