Why digital sovereignty matters with DNS.SB

DNS.SB is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so DNS.SB scores best on data residency.

DNS.SB 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 DNS.SB together with your other vendors and gives a total score, a heatmap and the main risk drivers.
