Philipp Holzmann’s core message was that digital sovereignty in cloud computing must be translated from political concern into concrete, auditable technical criteria. Speaking from the German Federal Office for Information Security, he framed the issue through Europe’s dependence on non-European digital infrastructure: only 20% of infrastructure and technologies come from the EU, while more than 70% of widely used AI base models come from the US. He stressed that dependencies are not inherently bad and that sovereignty does not mean autarky, but recent geopolitical and regulatory events show why governments and companies need a clearer view of which cloud services they can use autonomously, securely, and under conditions they understand.
