Denmark moves toward digital sovereignty, leaving Microsoft behind in the public sector

  • Denmark's Ministry of Digitalization will begin migrating from Microsoft to free software such as LibreOffice and Linux in 2025.
  • Main motivations: reducing technological dependence on the US, protecting data, and optimizing costs.
  • The cities of Copenhagen and Aarhus have also begun phasing out Microsoft solutions, citing similar concerns.
  • The process is gradual and reversible: if insurmountable problems arise, a temporary return to Microsoft is contemplated.

Denmark and Linux

Denmark has initiated a significant change in its public administration with the aim of stop depending on Microsoft services and programs, betting on open source alternatives such as Linux and LibreOfficeThis decision responds to growing concerns about technological dependence on large foreign companies and the need to strengthen national digital sovereignty.

The Ministry of Digitalization, led by Caroline Stage Olsen, has confirmed that within a few months more than half of the staff will migrate to Linux and LibreOffice environments, with the intention that by the end of the year the entire staff will be using only free software. The transition not only involves abandoning Office 365 and Windows, but also changing the ministry's technological culture, preparing employees to work with more open and locally controlled systems.

A planned process with room for reversibility

Minister Olsen has clarified that migration will be carried out progressively, starting with half the staff and extending to the entire ministry if the adaptation is successful. Should any difficulties arise that interfere with daily tasks, a temporary return to Microsoft solutions is planned while other alternatives are sought. However, the commitment to reducing technological dependence is firm:We will not move towards our goal if we do not start", Olsen has declared in various Danish media.

The adoption of free software in Danish public administration is part of a broader trend in Europe., where other regional governments, such as in Germany, , are also promoting open alternatives to reduce their technological dependence. The Danish experience can serve as an example for other countries seeking greater control over their digital infrastructure.

Precedents and European context

Denmark is not an isolated case: its main municipalities, Copenhagen and Aarhus, They have already started their own gradual abandonment of Microsoft technology., motivated by both cost and concern about the dominance of large technology companies in their systems. This phenomenon is part of a broader movement within Europe, where other regional governments, such as Schleswig-Holstein in Germany, are also moving toward open source solutions to reduce monopoly risks and strengthen national control over public data.

Challenges of Denmark's transition and vision for the future

The transition to free software requires both technical and cultural adaptation.Experts point out that success depends on staff training and strong IT skills within institutions to fully exploit the benefits of open source software. Minister Olsen and other Danish digital leaders have emphasized that they do not intend to "turn their backs" on innovation or international companies, but rather to ensure that Denmark never becomes so dependent on a few providers that it loses its ability to respond in critical situations.

Denmark's commitment to digital sovereignty is already being closely watched in other EU countries., where the European Commission is debating new legislation and promoting local alternatives to the cloud and artificial intelligence, reinforcing the trend of looking beyond large US companies in the management of public infrastructure.
