Wildix: sovereignty score and 8 European alternatives

Wildix is a VoIP and unified communications provider that brings calling, chat, video and collaboration together on one platform. Its portfolio includes x-bees, a platform for calls, contact centre and meetings with AI features, mobile apps for iOS and Android, and video meetings and webinars. With WebRTC, website visitors can call a business with one click, without downloading software or dialling a number. Integrations exist with Salesforce, HubSpot, Outlook and Teams, among others. The website names a cloud phone system as a delivery form.

According to its website, Wildix operates through several legal entities: Wildix OÜ, a holding company in Tallinn, Estonia, Wildix UK Limited in Coventry, and Wildix Inc. in Columbus, Ohio, in the United States. The site describes Wildix as an AWS partner and displays ISO 27017 and 27018 certification badges, but it does not state data centre locations. The software is not open source. For a cloud deployment, therefore, ask in which regions your data is processed and which entity is your contracting party.

Why digital sovereignty matters with Wildix

Wildix is headquartered in IT 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 Wildix scores best on data residency.

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