InterSession

InterSession is a modern 3270 session manager for mainframes that gives all users secure, fast and convenient access to their applications.
After logging on the user is presented with a menu of authorized applications and also gives the users Single Sign-On access. InterSession supports all current IBM mainframe operating systems (z/OS, VSE and VM), and all VTAM application host systems (i.e. CICS, TSO, IMS,...). The TN3270 support supports all current IBM TCP/IP stacks and TCPaccess from CA. InterSession comes with migration tools to help you migrate from old session managers such as Net/Master and TPX.

And you have the InterSession Web Gateway so you can say "goodbye" to TN3270 emulators meaning no installation or support outside the mainframe!
