Why digital sovereignty matters with Relay42
Relay42 is headquartered in NL and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in FI, also within Europe.
Data is hosted exclusively in the EU, so Relay42 scores best on data residency.
Relay42 is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.
What this means for your organisation depends on your whole stack and context. The free assessment weighs Relay42 together with your other vendors and gives a total score, a heatmap and the main risk drivers.
