Host On-Demand (HOD) is an IBM product that provides secure, encrypted 3270 terminal emulation service over the Internet. It also provides a secure FTP service for file transfers to and from the administrative mainframe, or a user-customizable FTP service for file transfers to/from other computer systems.

HOD is a web-based application so you can use it anywhere. With HOD, you can access the administrative mainframe from any computer that has Internet access, once you have completed the simple applet installation. And HOD is fully supported by the IT Help Center.


  • Secure encrypted transmission – HOD protects against security vulnerabilities when transferring data between your PC and the mainframe.
  • Automatic installation – HOD automatically installs the first time you access it. A few clicks of the mouse and HOD downloads, installs, and is ready to use.
