Tun Plus

Innovative Access Management

For organizations that require broader integration or flexibility to deploy via multiple technologies, Esker offers Tun Plus for complete enterprise resource access. Incorporating two powerful solutions ― PC-to-Host and multi-user Windows - Tun Plus offers true innovation in host access and host access management.

By choosing the Tun Plus License, organizations can deliver host access to every user, at any client device, on any platform and at any location. This breadth of delivery is made possible by Esker's redesign of Tun Plus as one product embracing two solutions:

  • Tun Plus PC-to-Host: Unrivaled host, database, and network-utilities access from any PC running Windows ® 10, 8 or 7
  • Tun Plus multi-user windows: Complete access for virtually any client type via Microsoft ® Windows Server ® with Remote Desktop Services

Tun Plus allows organizations to keep pace with the latest developments in connectivity and provide all users - green- screen power users, occasional Windows-style users, or mobile and remote users ― with the right level of access to business-critical information resources.

An innovation in host access management, Tun Plus helps organizations consolidate all host access needs under one product and vendor, relieve system administrators, support personnel and reduce the costs of providing host access.

Complete Tun Plus

Tun Plus delivers comprehensive host access plus broad connectivity to leading databases and critical network utilities.

Customizable terminal emulation

Tun Plus provides terminal emulation for more than 30 host types, including IBM ® 3270 and 5250 - as well as full 3287 and 3812 printer support ― HP ® , DEC ® VT, SCO ® Unix and more.

Powerful Tun Plus customization tools let administrators create user-friendly Windows-style emulation views - adding colors, graphical toolbars and function-key panels, mouse support and clickable hot spots. Customization is easy with drag-and-drop keyboard mapping and over 340 programmable actions.

Network utilities

Tun Plus also includes TCP/IP connectivity to critical network resources. FTP makes file and printer sharing easy. Also included are a full range of server-based components - FTPD and RSHD.

Shared Technologies

As user populations or deployment needs evolve, Tun Plus helps organizations manage the change. Shared technologies unify the PC-to-Host and multi-user Windows solutions, and enable easy migration for user, administrator and IT manager.

Workspace

All solutions feature a tabbed Workspace that allows users to launch multiple sessions from diverse hosts at one time. The multi-document Workspace promotes productivity by streamlining information integration.

Full-featured clients

All two solutions offer the same full-featured clients - with graphical toolbars, keyboards, client-side macros and other user-oriented functions
