Control and streamline the way users access applications.

InterSession simplifies the process of logging into mainframe applications. Once users are signed in, they can access all the mainframe applications they are authorized to from customizable menus, without wasting time and effort logging into and out of each one individually. They can effortlessly switch between applications and cut and paste information from one to the other.

Single Sign-On

InterSession gives users Single Sign-On access to all authorized VTAM applications. Applications can be set up for seamless user access without userid/password prompts. When supported, InterSession can use pass tickets instead of passwords to enhance security. InterSession also works well together with all external Single Sign-On products.

Web Browser and iOS/Android App Support

Access your mainframe applications using your favorite Web Browser or iOS/Android device.

Built-in TN3270 Server

InterSession handles TN3270 sessions with its built-in TN3270 server without using the TCP/IP stack TN3270 support; saving CPU cycles and making the configuration easier to manage.

Sysplex Support

In a sysplex all Intersession instances work together as one. This means InterSession automatically:

  • Replicates all changes and settings between instances
  • Load balances, and has backup for, the user sessions

A Web Browser is all you need.

InterSessions built-in web server makes it possible to access your 3270 applications using your web browser, without extra software installed in the workstation. The Web Gateway runs completely within the mainframe and there is no middleware involved. It is designed to be compatible with all leading modern browsers and uses cutting edge technology; such as Ajax and XHTML, when available.

  • Reduced Client Software cost and administration.
  • Little to no end-user training required.
  • OS/hardware independent client access.
  • Centralizes 3270 access and control on the mainframe.
