Data sovereignty means data is governed by the laws of where it is stored. Learn how it differs from data residency and why it shapes vendor choice.

Data sovereignty is the principle that data is subject to the laws and governance of the country in which it is collected or stored. For European organizations, it means ensuring data, and the rules that govern it, remain under EU jurisdiction. Data sovereignty influences vendor choice, hosting location, and protection against extraterritorial data access by foreign authorities.
Data residency and data sovereignty answer different questions. Residency asks where the data is stored, with hosting location as the primary lever, and matters for compliance and latency. Sovereignty asks whose laws govern the data, with legal jurisdiction as the primary lever, and matters for control and protection from foreign access.
A European public-sector buyer cannot adopt a tool whose data, even if stored in the EU, is ultimately subject to a foreign government's access laws. Data sovereignty, not just residency, is the deciding factor. This is structurally hard for US-headquartered vendors to fully satisfy and is a clear advantage for European-built platforms. Corma's European footing, EU hosting, and GDPR-native design directly address this concern.
Data residency is about where data physically sits. Data sovereignty is about which jurisdiction's laws govern it. Data can be resident in the EU yet still subject to foreign laws if the vendor is foreign-controlled.
Because European organizations, especially public bodies, increasingly require that their data stays under EU jurisdiction, free from extraterritorial access laws.
A vendor's headquarters and ownership can subject data to foreign laws regardless of hosting location, which is why European buyers favor European-built platforms.
