EU hosting isn't the same as EU jurisdiction.

Choosing a European data center does not necessarily mean your authentication provider is independent of US jurisdiction. The provider's corporate structure, applicable laws, subprocessors, and infrastructure all matter when evaluating data sovereignty.Hanko is operated by a Germany-based company and offers EU-hosted cloud infrastructure as well as self-hosting options for teams that require greater control.
