Sovereign data centres are facilities that store and process information under national jurisdiction to ensure security and regulatory compliance [1].
This shift toward digital sovereignty matters as governments and corporations seek to protect sensitive data from foreign surveillance and legal reach. By isolating infrastructure, nations can ensure that their most critical information remains subject only to their own laws.
Philippe Pasquier, professor and director of the Metacreation Lab for Creative AI at Simon Fraser University, said the concept in a recent interview [1]. He described these facilities as environments designed to meet specific security requirements, often utilizing air-gapped infrastructure. Air-gapping physically isolates a secure network from the public internet, preventing remote cyberattacks.
Global initiatives illustrate the growing demand for this model. In Brussels, Google Cloud has inaugurated a sovereign innovation centre to target European public markets [2]. In Montréal, Saab has proposed a secure data centre intended for potential Gripen fighter jet operations [3].
France has seen a significant pivot toward these systems. French state cloud orders for 2025 total 84 million € [5]. This represents an increase of 62% in state cloud orders compared with the previous period [5].
The French government is increasingly distancing itself from U.S. providers in favor of local alternatives. Currently, 99% of French state cloud projects are oriented toward European providers [5]. This trend highlights a broader movement toward the "souverain SASE" — a secure access service edge designed for managing sensitive data [4].
These centres allow nations to maintain a physical and legal perimeter around their data. By controlling the hardware and the location of the servers, governments can prevent foreign entities from accessing state secrets or citizen records through extraterritorial legal requests [1].
“Sovereign data centres are facilities that store and process information under national jurisdiction.”
The proliferation of sovereign data centres signals a retreat from the globalized, borderless vision of the early internet. As nations integrate AI and cloud computing into critical infrastructure, the risk of foreign data interception grows. By prioritizing air-gapped systems and local jurisdiction, countries are treating data as a strategic national asset similar to energy or water, effectively creating digital borders to ensure national security.
