OS2 - Public Digitalization Network in Denmark

OS2’s purpose is to strengthen public digitalisation through collaboration and shared ownership

We bring public bodies together to develop and maintain common digital solutions, ensuring long-term sustainability, transparency, and control.

As an organisation of public bodies in Denmark, OS2 works with open source software to give public authorities direct ownership of the code, freedom to choose vendors, and the ability to develop solutions — often more cost-effectively — based on real public needs.

Background


OS2 is a collaborative organisation of public bodies in Denmark.

The organisation was established on 24 April 2012, when five Danish municipalities — Ballerup, Syddjurs, Sønderborg, Ishøj, and Copenhagen — decided to formalise an existing practice of collaboration around shared digital solutions.

OS2 was created to provide a structured framework for cooperation when public authorities face common digital needs that are not adequately addressed by existing solutions.
