ServerMask 4.0
ServerMask 4 for IIS modifies your Web server's "fingerprint" by removing unnecessary HTTP response data, modifying cookie values, and suppressing application-layer error messages for PCI compliance. Successful anti-reconnaissance makes it likely hackers will try the wrong exploits first and be snared by your current firewall and intrusion detection systems. New in v4: 64-bit support, per-site configuration, and much more.
