Come on Fortune 1000, make our jobs more difficult!
Server anonymization with a tool like ServerMask will make your Web site less vulnerable to hackers by removing signatures that betray your Web technologies and by ensuring that exploit attempts are more likely to trigger your firewalls and intrusion detection systems.
