Chapter 1 Introduction

Tectia offers software tools to secure end-to-end communications within corporate networks. Tectia client/server solution allows secure network services over an unsecured network, such as the Internet.

Tectia products can be deployed cost-effectively to large corporate networks, because their installation and maintenance can be managed centrally.

The award-winning Secure Shell or SSH technology provides secure encrypted and authenticated communications between two non-trusted hosts. Users can establish secure connections to remote hosts, execute commands on the remote hosts securely, copy remote files securely, and forward X11 sessions (on Unix). Arbitrary TCP/IP ports can also be forwarded (tunneled) over a secure channel, enabling secure application connections, for example, to an e-mail service.

Tectia products are based on Secure Shell (SSH or SecSh) technology originally developed by the founders of Tectia Corporation, formerly SSH Communications Security. The Internet Engineering Task Force (IETF) has standardized the Secure Shell protocol, see RFC 4251 at
