IVT is a Windows-based VT220 terminal emulator that provides secure connections to remote hosts via telnet, SSH, RLOGIN, NetBios, or serial setup. It allows multiple sessions of different types in a single window with tabbed interface.

But that's not all. IVT goes above and beyond what PuTTY can do, making it an excellent choice for those who use PCs to access remote hosts. With fast, accurate VT220 terminal emulation, large tabbed screens, multi-session support, color options, and fast copy / paste, IVT is perfect for Unix text-mode applications such as EMACS, VI or Midnight Commander.
If security is a concern, IVT has you covered. You can use SSH or the Kerberos V5 authentication and encryption support for secure authenticated login.
For those who administer or utilize large networks with many machines, IVT allows you to initialize your working environment with just a few mouse clicks. Logging in to an array of hosts with either Telnet, Kerberized Telnet, SSH or modem, starting programs there, automatically analyzing the output, customizing the keyboard and screen - all of this is easily achieved with IVT.
What's more, the software is designed to work in environments with hundreds of Unix machines, making life in such environments that much easier. Once you get used to creating sessions with a few clicks and switching between 10, 20 (or even more) parallel sessions without losing track, you'll wonder how you ever got along without it :-)
