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 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 a database server.

Tectia products are based on Secure Shell technology originally developed by the founders of SSH Communications Security. The Internet Engineering Task Force (IETF) has standardized the Secure Shell (SSH) protocol, see the original RFC 4251 at https://www.ietf.org/rfc/rfc4251.txt.

The future-proof design of the SSH protocol allows extensions, for example, the SHA-2 @ssh.com algorithms introduced in 2011 in Tectia Client/Server 6.2 version. Tectia Quantum Safe Edition introduced multiple Post Quantum Cryptography (PQC) Hybrid Key Exchange algorithms in 2022 in Tectia Client/Server 6.6 version to address the quantum threath.
