Executive Summary

The German federal administration in 2025 relies heavily on proprietary software from US corporations, particularly Microsoft. A minor inquiry by The Left Party demonstrates that the Federal Ministry of Defense uses approximately 250,000 Microsoft workplaces, while alternative systems remain the exception. Only the Foreign Office and the Federal Ministry of Economics show higher open-source shares. Spending on US software licenses increased from 74 million euros (2017) to 481 million euros (2025).

Despite coalition promises to reduce monopoly dependencies, the federal government remains trapped in proprietary US software. The published figures illustrate a credibility problem: while the government proclaims "digital sovereignty," Microsoft spending increases disproportionately. Particularly for security agencies (Interior Ministry, Federal Police), open-source remains marginal – a strategic weakness in times of geopolitical tensions.

Detailed Summary

Microsoft dominance varies considerably between agencies. The Federal Ministry of Finance and Customs manage 63,588 Microsoft licenses, while open-source tools (OpenDesk, LibreOffice) are only used 660 times there. The Ministry of Transport operates 310 pure Linux computers (Debian/RockyLinux), the Environment Ministry runs five Ubuntu systems. The Ministry of Justice reports only four workplaces with exclusively alternative software.

An exception is the Foreign Office: with 12,030 Debian computers versus 16,714 Windows systems and LibreOffice as standard office software, it possesses a 25-year open-source history. The Federal Ministry of Economics operates 320 pure Linux computers.

The cost explosion reveals structural problems. Microsoft spending increased sixfold within eight years; in 2025 it stands at 481 million euros plus undisclosed items for the Federal Chancellery and BND. The coalition agreement promised "central strategic control" of IT procurement to reduce monopoly dependencies. This transformation process remains marginal so far. Additionally, waste potential is evident: framework agreements commit large volumes, while actual orders fall significantly below. Multiple ministries commission identical products (e.g., Adobe licenses) individually rather than centrally.

Key Findings

  • 481 million euros for Microsoft licenses in 2025 (increase of 543% since 2017)
  • Federal Ministry of Defense: ~250,000 Windows workplaces with minimal open-source use
  • Foreign Office as an outlier with 42% Linux share and established open-source culture
  • Security agencies (Interior Ministry, Federal Police) only equipped with alternatives in ~14% of cases
  • Coalition goals on digital sovereignty show little measurable progress after one year

Critical Questions

  1. Data Quality: Are the BND and Federal Chancellery figures completely verifiable, or does secrecy preclude comprehensive cost analysis?

  2. Framework Agreements: What specific volumes were agreed upon, and in how many products do orders fall below 50% of contract volume – what is the savings potential?

  3. Causality: Does Microsoft dominance lead to better security (proprietary audits, support), or is dependency perpetuated through path dependency and vendor lock-in?

  4. Implementation Risk: How long would migration of 250,000 Federal Ministry of Defense workplaces to open-source take, and what downtime risks arise?

  5. Conflict of Interest: Are there documented Microsoft lobbying activities toward federal ministries that influence contract renewals?

  6. Alternatives: Why do the Foreign Office and Economics Ministry successfully use Linux while security agencies reject it – are technical or organizational barriers decisive?

  7. Comparability: How do other EU states (France, Netherlands) position themselves regarding open-source shares in federal administration?
