Practical Guide for EU Governments: Evaluating Open Source Alternatives vs. Commercial Software

Recent geopolitical developments, notably shifting attitudes from the United States toward the European Union, have significantly raised concerns about digital sovereignty and the potential for external digital influence or coercion. Consequently, EU governments are increasingly motivated to explore alternatives to traditional commercial software, especially those originating outside the EU, to mitigate risks, reduce costs, and ensure full regulatory compliance.

Cost Analysis per User

• Microsoft Office 365 Business Standard: Approx. €126/user/year. LibreOffice: License free, estimated maintenance & support €15/user/year (community-based).
• Microsoft Outlook/Exchange: Approx. €60/user/year. Thunderbird/Open-Xchange: Licensing free, support cost approx. €10/user/year.
• SharePoint: €50/user/year. Nextcloud: License free, approx. €20/user/year including hosting and professional support.
• Microsoft Windows 11 Pro: Approx. €50/user/year (volume licensing). Linux Distribution: Licensing free, estimated annual support and management €25/user/year.

Total Estimated Annual Savings

• Commercial Suite: €286/user/year
• Open Source Suite: €70/user/year
• Potential Savings: €216/user/year (~75% cost reduction)

Compliance with EU Regulatory Frameworks

1. NIS2 Directive

• Open-source solutions provide transparency, facilitating faster vulnerability identification and remediation.
• Active community and vendor security updates ensure compliance with NIS2 requirements.

2. Cyber Resilience Act

• Open-source platforms (Nextcloud, Linux) emphasize security-by-design, aligning with EU Cyber Resilience standards.
• Rapid community and enterprise-driven incident response capabilities ensure alignment with EU cybersecurity compliance.

3. EU AI Act

• Open-source solutions offer enhanced transparency, aiding compliance with the EU AI governance frameworks.

Strategic Considerations

• Digital Sovereignty: Open-source software reduces dependency on non-EU vendors, strengthening EU digital sovereignty.
• Transparency & Trust: Visibility of open-source code enhances trustworthiness, aligning with EU regulatory expectations.
• Flexibility & Customizability: Open-source alternatives allow easier adaptation to evolving regulatory and governmental requirements.

Implementation Recommendations

• Initiate gradual migration starting with pilot projects and non-sensitive applications.
• Invest early in training and building robust support infrastructure.
• Conduct regular cybersecurity audits and compliance assessments to ensure ongoing regulatory adherence.

Transitioning to open-source software significantly reduces costs, ensures full regulatory compliance, and reinforces digital sovereignty. Strategic investments in support infrastructure and employee training facilitate a sustainable and resilient digital governance model for EU governments.

Transitioning all European Union (EU) governmental institutions from commercial software to open-source alternatives could result in substantial financial savings. Here's an analysis based on available data:

Public Sector Employment in the EU

As of the first quarter of 2024, the public administration and defense sector employed approximately 14.5 million individuals within the EU. Statista

Per-User Cost Comparison

Based on previous analyses, the annual costs per user are:

• Commercial Software Suite: €286 per user
• Open-Source Software Suite: €70 per user

Potential Total Savings

By adopting open-source software across all public administration and defense employees, the EU could achieve:

• Total Annual Savings: 14.5 million users × €216 savings per user = €3.132 billionOECD

Additional Considerations

• Implementation Costs: Initial investments in training, support infrastructure, and potential migration expenses should be accounted for.
• Long-Term Benefits: Beyond direct financial savings, benefits include enhanced digital sovereignty, improved compliance with EU regulations, and increased flexibility in software customization.

This analysis underscores the significant economic advantages of transitioning to open-source software within EU governmental bodies, alongside strategic benefits in autonomy and regulatory alignment.

Finally, a personal note to my American friends: This guide is written purely from a practical, economic, and strategic perspective and not as a critique. I'm forever grateful for the exceptional education and experiences I received in the United States, and I deeply value the friendships and bonds built over the years. However, these are challenging times, and when financial pressures mount, every opportunity to responsibly save money matters. Ultimately, this guide reflects a necessity rather than a preference—saving resources to ensure resilience and continuity in tough times is something we can all understand and appreciate.
