OpenDesk – the top-of-the-line office and collaboration suite
Introduction
An Open-Source Digital Workplace
OpenDesk originated from the “Sovereign Workplace” initiative of the Federal Ministry of the Interior and has been further developed by the Center for Digital Sovereignty (ZenDiS) since 2024. Instead of developing a new standalone solution, OpenDesk brings together proven European open-source applications under a common, centrally managed interface - ranging from file management to groupware and video conferencing.
How OpenDesk Is Structured Technically
At its core is a unified identity and access management system that provides single sign-on access to all application modules. Deployment is container-based on Kubernetes, allowing OpenDesk to be operated both on-premises and in managed cloud environments.
Univention Nubus, with its Keycloak-based identity and access management, ensures consistent login and access rights across all modules.
All components are designed for use on Kubernetes—they are scalable, portable, and independent of any specific infrastructure.
The Components of the Suite
Identity & Access
One login for all applications
User management is not an additional feature, but rather the connecting element of the architecture. All modules access the same identity via standardized interfaces and preconfigured integration packages.
- Single sign-on across all integrated modules
- Centralized permission assignment and role management
- Standardized interfaces for data exchange between modules, such as between file storage and groupware
- Flexibility to add or replace individual components without interfering with the core architecture
Operating Models
Community Edition and Enterprise Edition
OpenDesk is available in two versions and can be operated independently or purchased as a managed service.
