First-id: sovereignty score and 8 European alternatives

First-id is a French identity infrastructure for first-party data. With first-connect, every visitor who gives consent receives a deterministic, persistent identity across the sites and apps of publishers, broadcasters, brands and retailers, so that web, app, CRM and transaction data can be linked. First-boost enriches the own identity graph of adtech and martech companies with signals from the First-id graph. First-translate converts an audience or dataset from one identity system to another, for example starting from a hashed email address. The services are offered as a platform and through integrations with advertising and measurement partners.

First-id is based in Issy-les-Moulineaux, France, so it falls under EU law and the GDPR. Its privacy policy cites GDPR rights and a data protection officer, and identification relies on consent. The legal notice names Hostinger only as the host of the website. Where the identity service and graph are hosted is not stated, and no self-hosted variant is described. Ask about the hosting location, the sub-processors and the legal form before you have personal identifiers processed.

Why digital sovereignty matters with First-id

First-id 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 First-id scores best on data residency.

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