Whaller: sovereignty score and 8 European alternatives

Whaller is a French collaboration platform for intranets, digital workplaces and internal social networking. Organisations switch on only the modules they need: discussions, forms, file management with co-editing, member management, video meetings, tasks and Kanban, calendars, surveys, a dedicated email service and electronic signature. Mobile apps and an AI assistant are available. Whaller ARENA targets large organisations, consortia and public bodies, and Whaller DONJON is a physically dedicated platform variant. The service is delivered as SaaS.

Whaller SAS is based in Suresnes, France. According to the vendor, a French offer is provided in partnership with OVHcloud, with managed email hosted in France; the company's website runs on OVH in Roubaix. The vendor describes DONJON as SecNumCloud-qualified (ANSSI). No parent company outside Europe was found. For European organisations that want data kept under French and European law, it is a relevant alternative to Microsoft Teams or Viva Engage.

Why digital sovereignty matters with Whaller

Whaller is headquartered in FR 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 Whaller scores best on data residency.

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