dus.net: sovereignty score and 8 European alternatives

dus.net is a German telecommunications provider offering cloud telephony with cloud PBX plans, SIP trunking for existing phone systems, a VoIP API for developers and softphone apps for iOS and Android. Its SIPONA web platform brings together telephony, meetings, CRM, ERP and AI assistants in one browser application. Organisations use these services as hosted telecom and cloud offerings for business communication.

The operator is dus.net GmbH, a German company. The public pages name no shareholder or parent group, so no foreign owner is identified. According to the SIPONA page, the platform runs on the operator's own racks in a data centre in Düsseldorf, external carriers are used only to terminate calls to other networks, and the AI engine runs on the company's own hardware in Germany. A general GDPR or data processing agreement statement is not on the public pages, so a European organisation should request those terms and the list of sub-processors before subscribing.

Why digital sovereignty matters with dus.net

dus.net 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 dus.net scores best on data residency.

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