Port80 Software Introduces ServerMask, a Windows Web Server Software Module for Enhanced Security

SAN DIEGO, Calif., - June 3, 2002 - Port80 Software, Inc., an innovative developer of software modules for Microsoft's Internet Information Server (IIS), introduces ServerMask for IIS, a new Web server software module that changes, hides or obscures server header data in HTTP transactions. Web site administrators, developers and owners are very aware of the ongoing danger of unwanted intrusion and hacking into Web sites, and ServerMask enhances Web server security against visual hacking & server-specific exploits.

"Finding out information about your server and operating system is the first goal of a potential intruder, so why let them know what you are running?" said Joseph Lima, COO of Port80 Software. "ServerMask obscures the identity of your Web server by safely and easily removing or modifying the unnecessary Server header in HTTP responses. The software is a convenient, cost effective solution to discourage low-level crackers and baffle their malicious scripts that try to discover your technology platform."

ServerMask provides control over what server header data, if any, is visible in HTTP responses. Developers and administrators can easily change the header to any string desirable, randomize it to choose amongst ten common Web servers, or simply remove the header altogether. ServerMask is a fast, robust IIS module that can be installed and configured in less than two minutes.

ServerMask features include:

  • Small memory footprint (279KB for an ISAPI filter and MMC snap-in extension)
  • Super fast ISAPI filter with no noticeable server performance impact
  • Easy to configure with MMC interface
  • Variety of masking options
  • Remove server header
  • Randomize server header among common servers
  • Customize server header
  • Simple to install/uninstall


ServerMask runs on Windows NT, 2000 and XP with IIS 4.0, 5.0 and 5.1 and is compatible with major third party server-side scripting platforms. The new IIS server module is available for a free 30-day trial download and $24.95 for a permanent single server license at www.port80software.com.
