About The European Digital Resilience Index (EDRIX)

The European Digital Resilience Index (EDRIX) was created in response to two fundamental and interconnected crises facing the European Union: a severe and growing economic dependency on non-European technology, and a profound geopolitical realignment that transforms this dependency into a critical strategic vulnerability.

Our mission is to provide a clear, data-driven, and honest assessment of Europe's digital sovereignty. We move beyond traditional policy analysis to measure tangible, real-world outcomes across the entire digital ecosystem. The EDRIX is not an academic exercise; it is a diagnostic tool designed to expose structural weaknesses, identify hidden strengths, and guide the industrial policy now urgently needed to build a resilient and autonomous digital future for Europe.

What is the EDRIX?

The EDRIX is a composite index that provides a holistic measure of a nation's ability to create, deploy, and utilize technology independently. To capture this complete picture, the index is built upon a framework that integrates five distinct data pillars:

  1. Public Policy: The maturity of a nation's top-down strategic commitment to open technologies.
  2. Developer Ecosystem: The domestic capacity to build and maintain sovereign technology.
  3. Grassroots Adoption: The on-the-ground digital choices of citizens and businesses.
  4. Private Sector Digital Health: The technological sovereignty of the national private sector.
  5. Public Sector Digital Health: The resilience of core government digital infrastructure.

Alongside the main EDRIX, we also present the European Open Technology Readiness Index (EOTRIX), a focused score that specifically measures a nation's adoption and readiness for open technologies, which we believe are a key enabler of long-term resilience.

Our Principles

Our work is guided by a core set of principles:

  • Data Over Opinion: Our findings are grounded in quantitative, verifiable metrics, not our subjective assessments. We believe that an honest diagnosis requires impartial data.
  • A Holistic, Ecosystem-Based View: True sovereignty is not merely a reflection of government policy. It is the sum of a nation's entire capacity, from its developers and businesses to its public institutions and citizens.
  • A Tool for Action, Not Just Analysis: This index is designed to be used. Its purpose is to help policymakers, industry leaders, and citizens identify specific strengths to build upon and critical weaknesses to address.
  • Transparency and Openness: Our methodology is published, and our primary data sources are public. We believe that the process of measuring sovereignty must itself be sovereign and transparent.

Who We Are

The EDRIX was created and is maintained by Stefane Fermigier, a veteran Open Source tech entrepreneur.

Stefane is the founder and CEO of Abilian, a French Open Source company.

He is also a member of the EuroStack Industry Initiative, which provides the main motivations to create the index. We are a volunteer-driven, non-lobby, and non-partisan collective of technologists, economists, entrepreneurs, and policy experts from across Europe. We are united by a shared sense of urgency and a common goal: to help build a sovereign, open, and resilient digital future for Europe. We believe that Europe has the talent, the resources, and the foundational values to control its own digital destiny. The EuroStack Initiative works to provide the data, frameworks, and policy recommendations needed to turn that potential into a reality.

He is also a co-founder and co-chairman of CNLL, the French Open Source business association, and of APELL, the European Open Source business association.

Data Sources & Acknowledgements

This index would not be possible without the foundational work of numerous organizations. Our analysis synthesizes data from a wide range of public and private sources, including:

  • The Asterès report, commissioned by Cigref, for the core economic analysis of digital dependency.
  • The European Commission's Open Source Observatory (OSOR) for its comprehensive country-by-country policy intelligence.
  • Publicly available data from GitHub on developer activity (on this specific US-based platform - we understand the limitations of this approach - contact us if you have relevant data sets from European platforms).
  • The EuroStack Industry Initiative and its public list of supporters.
  • The EuroStack Directory Project, a comprehensive list of sovereign digital technologies and solutions.
  • Market share data from independent sources such as Statcounter and the Cloudflare Radar dataset.
  • Original analysis of public and private sector domain infrastructure and web services using a dedicated toolbox.

Get Involved

The challenge of building a resilient digital Europe is a collective one. We welcome collaboration, feedback, and engagement from all stakeholders. To learn more about our work at EuroStack or to get in touch, please visit the EuroStack Initiative website.
