Didomi: sovereignty score and 8 European alternatives

Didomi is a privacy platform for consent and preference management. Its consent management platform (CMP) shows consent banners on websites, mobile apps and connected TV and supports several privacy regulations. The preference management platform collects first- and zero-party preference data across web, mobile, email and in-store touchpoints. Didomi also offers compliance monitoring that scans websites for trackers, scripts and vendors, handling of privacy requests (listed as early access) and server-side tagging through Addingwell, which it acquired in 2025. The service is delivered as SaaS, with SDKs, an API and a management console.

Didomi SAS is headquartered in Paris, France. A 2025 funding round was led by Marlin Equity Partners, a US investment fund described as the reference shareholder; for European organisations this is a US ownership link that may matter when assessing exposure to the US CLOUD Act. According to Didomi's privacy terms, hosting is provided by Amazon Web Services EMEA SARL in the EU, and Auth0 (US) acts as a processor for authorisation. No open-source or self-hosted option is described.

Why digital sovereignty matters with Didomi

Didomi 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. The ultimate owner is based in US. Foreign control undermines part of the certainty a European headquarters offers.

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

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