Say Goodbye to Daily Login Stress in Your Administration

How many times a day do you have to log in to complete administrative tasks? How often do your IT teams have to reset passwords or deal with inconsistent user accounts? In many public sector organizations, this is everyday reality: a confusing jungle of logins, passwords, and disconnected systems. Every specialized application requires a separate login – wasting time, patience, and valuable resources.

This constant juggling of credentials frustrates employees and ties up IT capacities that are urgently needed elsewhere. In an environment where efficiency, security, and data protection are essential, such complexity becomes a serious issue.

But there’s a better way: With Nubus, our central Identity & Access Management (IAM) platform with integrated Single Sign-on (SSO) portal, you provide users with simple, secure, and unified access to applications, services, and specialized procedures – bringing order to your system landscape.

Let’s work together to relieve the burden on your administrative IT!

Three Typical Starting Points – Do Any of These Sound Familiar?

In our work with IT managers from public administrations, we frequently encounter similar challenges. Perhaps you’ll recognize your own situation in one of these examples:

01.
Your current solution is inflexible and difficult to manage?
Many public administrations rely on legacy Identity & Access Management (IAM) systems that have evolved over time – and can no longer keep pace with the demands of modern IT infrastructures. These systems are complex to operate, slow to adapt, and require significant effort to integrate new applications. The result: lost time and stifled innovation.
02.
You’ve built your own solution – but made too many compromises?
What started as a pragmatic interim fix has become a long-term construction site. In-house developed systems quickly reach their limits when it comes to scalability, security, or interoperability. Maintenance is resource-intensive and ties up internal capacity that is urgently needed elsewhere.
03.
You’re not using a centralized IAM at all?
Without centralized identity management, a patchwork of individual logins, manually maintained accounts, and isolated processes emerges. The result: security gaps, inefficiencies, and an IT landscape focused more on administration than on innovation. This is especially burdensome in public administrations that rely on numerous specialized applications.

Do any of these situations sound familiar? Then it’s time for a solution that reduces IT overhead and supports your staff.

Frequently Asked Questions (FAQ) about Nubus and Single Sign-on in Public Administration

What distinguishes Nubus from traditional IAM systems?

Nubus is specifically designed to meet the requirements of authorities and public IT service providers. Unlike traditional Identity & Access Management systems, Nubus is based on open standards, is fully open source, and—thanks to its Kubernetes architecture—is ideal for containerized operation in modern infrastructures, whether in your own data center or the German administration cloud. Additionally, Nubus offers a particularly user-friendly web interface and integrated self-services that sustainably relieve IT departments.

Is Nubus compatible with existing systems?

Yes, Nubus can be easily integrated into existing IT environments. It offers standardized interfaces and ready-made integration packages, for example, for Nextcloud or Open-Xchange. Existing directory services such as Microsoft Active Directory or other LDAP-based systems can also be connected. This allows for a gradual rollout without disrupting the existing system landscape.

Does Nubus meet data protection and IT security requirements?

Yes, Nubus is fully compliant with the requirements of the GDPR and the BSI IT baseline protection. The software undergoes regular security audits and provides features such as two-factor authentication. Additionally, centralized user management enables clear access control, ensuring greater transparency and security in handling personal data.

What are the benefits of Single Sign-on in public administration?

A centralized Single Sign-on system like Nubus allows employees to access all necessary specialized applications and services with just one login. This not only reduces the administrative burden of managing passwords but also increases IT security by minimizing potential attack points. At the same time, it improves user-friendliness—an important factor, especially for digital work in government agencies.

How does Single Sign-on contribute to the digital sovereignty of public administration?

Single Sign-on with an open-source solution like Nubus helps public institutions break free from proprietary dependencies. Thanks to open standards and source openness, authorities retain full control over their identity data and can tailor or further develop the solution as needed. Thus, Single Sign-on is not only a convenience feature but a key building block for digital self-determination.

How does Nubus relieve IT departments in public institutions?

Through centralized user management, self-services such as password resets, and an intuitive web interface, Nubus significantly reduces recurring support requests. Integration is done via standardized interfaces — allowing applications to be connected and managed faster. This saves time and resources and creates capacity for strategic IT tasks.
