Sopht: sovereignty score and 8 European alternatives

Sopht is an IT efficiency platform that maps and helps reduce the cost and carbon emissions of large organisations' IT. It collects data automatically from the IT estate, shows cost and emissions per service, application, device or AI model, ranks recommendations by return in euros and CO2, runs scenarios with ROI modelling, and links actions to a budget and CO2 trajectory with owners. IT, finance and sustainability teams can then work from the same figures. The platform is delivered as SaaS.

Sopht is the trade name of Greenbuddy, a French simplified joint-stock company in Villeurbanne; no parent company is stated. The vendor's site does not say where the platform is hosted; only the website runs at Webflow (US), and the privacy policy says US providers are covered by the EU-US Data Privacy Framework or standard contractual clauses. France, the seat of the company, is therefore used as the working assumption for the platform. Ask about the hosting location, subprocessors and the data processing agreement. It is commercial software, not open source.

Why digital sovereignty matters with Sopht

Sopht is headquartered in France 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 Sopht scores best on data residency.

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