Why digital sovereignty matters with Rethink DNS
Rethink DNS is headquartered in IN, outside the EU. Contracts and data therefore also fall under non-European law. The GDPR applies through contractual terms, but in a conflict with local legislation you have less certainty than with a European vendor.
Rethink DNS hosts data in EU, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.
Rethink DNS is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.
What this means for your organisation depends on your whole stack and context. The free assessment weighs Rethink DNS together with your other vendors and gives a total score, a heatmap and the main risk drivers.
