Tectia Zero Trust Edition allows an efficient role-based access control (RBAC) to bring scalability to managing access to large server estates. By operating without permanent credentials like SSH keys or passwords, Tectia Zero Trust eliminates the costly process of managing or rotating credentials while also greatly enhancing system security by removing a significant potential attack vector. Additionally, it increases transparency by centralizing system access audit logs and optionally provides advanced auditing including session recording. It is a separate product enhancementad module for Tectia Client/Server that interoperates also with recent 3rd party Secure Shell implementations. Tectia version 6.5 or above is officially supported, however any Tectia version that supports SHA-2 signature algorithms can be configured to support Tectia Zero Trust if needed.
