The Pillars of European Digital Sovereignty

Each level of the European technology stack represents a fundamental step towards a strategically autonomous and secure digital ecosystem. Explore the pillars that define our commitment.

What's the challenge

Europe is dependent on foreign imports for over 80% of digital technologies used. In cloud alone, more than 70% of the market is controlled by 3 US companies, creating vulnerabilities in data control, supply chain resilience, and strategic decision-making. This dependence limits Europe's ability to set its own digital standards and protect its economic interests.

What we aim for

Technological independence gives Europe control over its digital future. By building a robust ecosystem of trusted European solutions, we enable businesses to innovate freely, ensure data remains secure and sovereign, and create new opportunities for growth. A digitally autonomous Europe means stronger competitiveness, better protection of citizens' rights, and the freedom to shape technology according to European values.

What we are building

The Tech Sovereignty Catalogue is a cornerstone initiative that maps Europe's digital capabilities across cloud, connectivity, cybersecurity, data, and AI. It connects innovative European companies with decision-makers, showcases market-ready sovereign solutions, and accelerates collaboration. Part of a coordinated effort to build Europe's sovereign technological stack, the Catalogue turns ambition into action—one trusted solution at a time.

Governance

The Catalogue is guided by a robust governance framework designed to ensure its integrity, consistency, and strategic value. At its core is an Advisory Board and a group of Expert Assessors, bringing together leading industry experts, researchers, academics, and policy specialists. They review submissions to guarantee that listed solutions are market-ready, sovereign by design, and meet high European standards.

In addition, partners contribute by sharing their expertise, networks, and resources. Their input helps maintain the catalogue’s quality and relevance, ensuring it remains a trusted tool for policymakers, businesses, and innovators across Europe.

Director of research, CEPS

In our seminal report on EuroStack, we sought to offer a pathway to achieve digital sovereignty, rooted in European values and strategic autonomy. The Catalogue promises to be a guiding light through this pathway, offering concrete solutions at all layers of the tech stack, and positioning itself as an inclusive platform for all innovators and stakeholders interested in European digital sovereignty.

Innovation Director, FBK

The need to strengthen the EU Digital Ecosystem is a pressing priority. The Eurostack catalogue represents a valuable effort to map and assess EU digital solutions to reach the EU digital autonomy. FBK plays an active role in this ecosystem, collaborating with companies and research institutions to design, develop and implement innovative digital solutions.

CEO, Open Knowledge Fundation

The Open Knowledge Foundation has been working towards equitable access to technology and information as a foundation for open societies for over two decades. The Tech Sovereignty Catalogue brings this mission to life by enhancing transparency, accountability, and resilience across Europe’s digital ecosystem. It sets a precedent for a truly open sovereign digital development that can be shared globally, especially benefiting the smaller actors, young innovators and SME’s everywhere, who rely on open, interoperable technologies to innovate, compete, and thrive.

Honorary Professor, UCL IIPP, Author of the EuroStack Report

The Catalogue is a concrete step toward building a sovereign, interoperable, and resilient European tech stack. Making visible European alternatives across the digital stack is a key first step toward reducing dependencies and enabling strategic public procurement to boost Europe’s technological and economic competitiveness. It strengthens our capacity to innovate in the public interest and in defence of democratic control over digital infrastructure.

Executive Director, AI and Society Institute, ENS-PSL

Digital autonomy is not just a technological imperative—it is a democratic one. This provides a crucial foundation for coordinating Europe’s home-grown digital capabilities, including AI, through the lens of autonomy, resilience, and shared public interest. At the AI and Society Institute, we believe that mapping these solutions is a vital step toward building a future where European values are embedded in the infrastructure that shapes our societies.
