Sovereign and resilient digitalisation of public administration
We develop software solutions for modern administration. With a focus on the OZG, register modernisation and scalable open source.
Software solutions for modern administration
As the backbone of our government system, public administration is one of the critical infrastructures (KRITIS) that require particular protection. Its digitalisation brings challenges: complex legal requirements, legacy systems into which modern technologies have to be integrated, and limited human and financial resources.
What’s more, there are isolated solutions and a highly heterogeneous IT landscape that has evolved over time. They complicate networking and cooperation between authorities. Protecting critical infrastructures in particular requires uniform and yet flexible IT architecture that meets the highest security requirements, especially in times of geopolitical tensions.
- OZG, RegMoG, GDPR, IT security laws and XÖV standards
- Integration of modern technologies into legacy systems
- Secure IT architecture for critical infrastructures
Master complex IT landscapes with ease
Our solutions make systems that have experienced decentralised growth interoperable. They help to implement legal requirements and securely incorporate communication and process standards.
Online Access Act (OZG)
Implementing the OZG requires the homogenisation of a heterogeneous system landscape. We translate communication scenarios, legal specifications, federal structures and technical requirements into practical, user-friendly solutions.
Register Modernisation Act (RegMoG)
Outdated, isolated data sets lead to additional work and media disruptions. We support the connection of registers to the National Once Only Technical System (NOOTS), from register analysis and interface development to operational support.
Interoperable systems
We connect systems that have experienced decentralised growth and in this way lay the foundation for efficient, secure digital administration.

Technology that connects
The digitalisation of administration is as diverse as those involved in shaping it. We therefore develop solutions that consider the technical, legal and organisational requirements of all parties involved.
As an experienced partner, we implement technical specifications sustainably and cost-effectively. We intentionally opt for scalable open-source solutions that enable reuse in accordance with the EfA principle (One for All) and meet the highest IT security standards.
- Well-thought-out solution designs and end-to-end architectures
- User-centred, NOOTS-enabled solutions
- Reusable open-source components
Who we work for
Our products and consulting services are aimed at all areas of public administration.
Municipalities, states and authorities
We implement technical specifications for you sustainably and cost-effectively, with scalable open-source solutions in accordance with the EfA principle.
Municipal IT service providers
As experts in implementing administrative digitalisation and register modernisation, we help you meet the requirements of contracting public agencies reliably and in contractual compliance. Our focus is on stable system architectures that minimise downtime.
Administrative process developers
A multitude of communication scenarios and technical standards make administrative processes complex. We help you comply with legal and normative requirements so that you can develop and offer efficient, cost-effective administrative processes.

Many years of experience in administrative digitalisation
As a member of the “Secure Data Exchange” expert committee of KoSIT, we help shape the administration’s IT standards and implement them in projects. Since 2018, we have been an official partner of the state of North Rhine-Westphalia for the implementation of the Online Access Act. Our OZG solutions enable E2E data exchange without media disruptions across various communication scenarios. This improves communication with citizens and businesses and eases the burden on day-to-day administration.
We are also your technology partner for the RegMoG: with register analysis, clear implementation pathways and SAK-compatible interfaces for connecting all registers to NOOTS. In this way, we lay the foundation for the Once-Only and EfA principles.
- Official OZG partner of the state of North Rhine-Westphalia since 2018
- Location specific certified according to ISO 9001 and ISO/IEC 27001
- Internal control systems externally assessed in accordance with ISAE 3402
