audriga: sovereignty score and 8 European alternatives

audriga is a migration service from audriga GmbH in Karlsruhe that moves email, calendars, contacts, files and other groupware data between mail platforms and storage systems. It is offered as a web-based self-service tool for hosters and internet providers, and as assisted migrations for larger projects. The company was founded in 2011 as a spin-off from the Karlsruhe Institute of Technology, and the service is delivered as a web-based service.

The imprint presents audriga GmbH as a German company with German managing directors. The privacy policy states that the service runs on infrastructure from Amazon Web Services in Ireland, OVH in France and several German providers, and that contracts limit processing to the European Union. Because AWS is a US-based provider, the choice of hosting region and the sub-processor list remain relevant for sensitive mailboxes. The service is not open source.

Why digital sovereignty matters with audriga

audriga 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 audriga scores best on data residency.

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