How z/Scope Anywhere works

Security Enhancement for your Terminal Emulation

Our web-based Terminal Emulator client solution is based on a 3-tier architecture composed of the Browser, the Server and the Host. The z/Scope Anywhere Server is a secure, high-performance HTTP / WebSockets server, which serves the web pages needed to run the z/Scope Anywhere Web Client on any HTML5-capable browser. Relying on the HTML5 technology, z/Scope Anywhere does not require any plugin to run. This simplifies the end-user access with a solid, but easy-to-adopt clientless solution. The 128-bit encryption provided allows users to securely access remote hosts over any network, and safely transfer files between systems.
