Auerswald: sovereignty score and 8 European alternatives

Auerswald is a German manufacturer of business telephony, based in Cremlingen near Braunschweig. Its range includes SIP and IP desk phones, DECT handsets, IP telephone systems for small and medium-sized businesses, and the COMuniq ONE cloud telephone system, which the company describes as a professional cloud phone system that combines voice functions. It also offers electronic manufacturing services for OEM customers.

Auerswald GmbH & Co. KG is run by members of the founding family, and the sources reviewed name no foreign parent company. Its desk phones and on-premise systems are used on the customer's own premises, while COMuniq ONE is sold as a cloud service. The company's pages do not state where COMuniq ONE data is hosted, so a European organisation should confirm the data-centre location and the contractual terms for the cloud product. Because the company is German and family-run, the main sovereignty question concerns the cloud service rather than the ownership.

Why digital sovereignty matters with Auerswald

Auerswald 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 Auerswald scores best on data residency.

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