Why digital sovereignty matters with Cozero

Cozero 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 Cozero scores best on data residency.

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