Securing Digital Sovereignty - Remaining Capable of Action in Public Administration
Public administration is facing increasing pressure: it must become more efficient, digital, and citizen-centric—while coping with limited resources, growing complexity, and rising dependence on individual IT vendors. Proprietary software solutions and closed platforms increasingly restrict the autonomy of many authorities.
Open IT solutions for public administration offer a way out: they enable authorities to regain control—over their data, the technologies used, and the development of their own IT strategy. Those who act with sovereignty can deliberately drive innovation, consistently implement data protection, and make independent decisions in the long term—serving both citizens and the public mission.
With open, standardized IT solutions for public administration, you lay the foundation for a flexible, future-ready administration that not only adapts to digital transformation but actively shapes it.
Secure Identity Management
Why Identity & Access Management is Essential for Public Institutions
The number of services, applications, and users in public administration is continuously growing. Without centralized control of identities and permissions, both effort and security risks increase.
A modern Identity & Access Management (IAM) system is therefore crucial: it protects sensitive data, simplifies processes, and ensures digital operational capability.
Nubus: Centralized IAM for Public Administration
All Applications, One Login – Simple, Secure, Transparent
Nubus is a modular IAM solution designed for public administration, enabling you to centrally manage user accounts and access rights through a single portal with Single Sign-on. Whether on-premises, in the cloud, or in a hybrid setup, Nubus offers flexible deployment. Built on open source and professionally supported by Univention, it lets you maintain control with maximum security and minimal effort.
One Login for Everything
Single Sign-on for Efficient Digital Administration
Multiple applications, multiple logins — this costs time, causes frustration, and increases security risks. With Single Sign-on (SSO), users log in just once to gain secure access to all relevant services. This not only simplifies daily work but also reduces the burden on your IT team.
Learn how SSO works with our software for public administration — and how it can help you modernize and secure your administration.
