Voys: sovereignty score and 8 European alternatives

Voys is a cloud communications system from the Netherlands for business telephony. It connects callers to the right colleague through a hosted virtual switchboard, so organisations do not have to run their own telephone exchange. The vendor describes the product as made and hosted in the EU and states that the service is ISO 27001 certified.

Voys B.V. is registered as a telecommunications provider with the Dutch regulator ACM. Its privacy statement says personal data is mainly processed within the EU and EEA, that transfers outside that area rely on GDPR safeguards, and that a data processing agreement is available. Subcontractors are named, including Voys Partner B.V. as telephony platform supplier. The product is a commercial cloud service and not open source. The sources used do not identify a foreign parent company, so for a European organisation the main questions are the processing locations and the subcontractor chain set out in the contract.

Why digital sovereignty matters with Voys

Voys 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.

Data is hosted exclusively in the EU, so Voys scores best on data residency.

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