On Thursday, September 24, Catherine Mayenobe, deputy general director of the Caisse des Dépôts group, and Henri d'Agrain, general delegate of the Cigref, took part in a discussion on the topic of digital sovereignty for Europe and how to measure the digital dependence of companies. The conversation was part of the program Tech&Co Business, hosted by Frédéric Simottel from the AIM Marseille. Digital sovereignty refers to a region or country's ability to control its own digital infrastructure, data, and technologies, rather than relying on foreign systems or companies. This topic has become increasingly important as nations seek to protect their digital economies from external influence and ensure technological independence. The discussion focused on the challenges Europe faces in maintaining control over its digital ecosystem, including issues related to data security, technology development, and reliance on non-European platforms and services. Both Mayenobe and d'Agrain emphasized the need for European companies to assess their level of digital dependence — that is, how much they rely on external digital tools, platforms, or infrastructure — to better understand their vulnerabilities and opportunities for self-reliance. The event was part of a broader conversation about the future of digital policy in Europe, especially in light of growing concerns about cybersecurity, data privacy, and the dominance of large tech firms from outside the continent. As the digital economy continues to grow, ensuring that European businesses and institutions are not overly dependent on foreign technologies has become a strategic priority for policymakers and business leaders alike. The Tech&Co Business program, which featured this discussion, will be available for viewing or listening to on Tuesday on BFM Business, a French financial news channel. The program regularly covers topics related to technology, innovation, and the business landscape in France and beyond.
