Single Sign-on for Public Administration
The Challenges
Why Many Administrations Reach Their Limits With The Login Process
In conversations with IT managers from public authorities, we repeatedly encounter similar challenges. Login structures have often evolved over time, are difficult to extend, or are slowed down by manual processes. Do any of these situations sound familiar?
01
Your Current Solution is Inflexible And Difficult to Manage
Many public authorities work with IAM systems that have evolved over time and today can barely keep pace with modern IT infrastructures. Adjustments take a long time, and new applications can only be integrated with significant effort.
02
You Have an In-House Solution, but Too Many Compromises
What once began as a pragmatic solution often becomes a long-term burden. In-house developed systems quickly reach their limits when it comes to scalability, security, and compatibility, and cause permanently high maintenance effort.
03
You Are Not Yet Using a Centralized IAM
Without centralized control, a patchwork of individual logins, manually maintained accounts, and manual processes emerges. The result is security risks, high administrative effort, and unnecessary complexity.
The Solution
Nubus Makes Single Sign-on Simple And Secure
With Nubus, employees gain centralized access to all relevant applications. A single login is enough to securely use specialized procedures, collaboration platforms, and internal services. At the same time, IT retains control over identities, permissions, and access.
-
Single Sign-on for all systems
One login is enough: access to connected applications is automatic and secure.
-
Centralized user management
Identities and access rights are managed in one central place, transparent, traceable, and efficient.
-
Self-services for employees
Reset passwords and manage accounts independently: less support effort for IT.
-
Kubernetes-ready and scalable
Operation in your infrastructure or in the government cloud, matching your requirements.

FAQ
Frequently asked questions about Single Sign-on with Nubus
Answers to the most important questions about Single Sign-on in public administration. From integrating existing systems to security and compliance and practical operation with Nubus.
Single Sign-on enables users to access multiple applications after only one login. After logging in, specialized procedures, collaboration platforms, and other systems can be used without having to authenticate again.
Single Sign-on simplifies everyday work, reduces password problems, and at the same time improvessecurity. Employees switch seamlessly between applications, while IT retains centralized control over access and authentication.
No. Smaller authorities also benefit from centralized login structures, less support effort, and unified user management. Especially with limited IT resources, automated processes can make a noticeable difference.
Yes. Nubus supports open standards such as LDAP, SAML, and OpenID Connect (OIDC). This allows numerous specialized procedures, collaboration solutions, and other applications to be integrated.
Yes. Existing Microsoft Active Directory environments can be connected and integrated into existing authentication processes. This also makes a step-by-step expansion of existing structures possible.
Yes. New applications can be connected at any time without fundamentally changing existing login structures.
Yes. Single Sign-on reduces the number of passwords users have to manage and enables centralized enforcement of security policies. In addition, Nubus supports modern authentication methods such as multi-factor authentication.
Yes. Nubus can be used in GDPR-compliant operating models and supports centralized management of identities and access rights.
Nubus supports established standards such as OpenID Connect (OIDC), SAML, LDAP, and Kerberos. Encrypted connections as well as modern authentication mechanisms are also part of the functionality.
