Why digital sovereignty matters with openDesk

openDesk 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 openDesk scores best on data residency.

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