Smart-ID: sovereignty score and 8 European alternatives

Smart-ID is an app-based electronic identity service from SK ID Solutions. Users register in the Smart-ID app and use it to authenticate themselves online, register in e-services and sign documents. E-service providers integrate it through an implementation guide, digital signing integration and a test service. According to the provider's website, the service is used in Estonia, Latvia and Lithuania, and has recently become available in Belgium. The same provider also offers Mobile-ID, timestamping and certificates that verify the identity of businesses.

SK ID Solutions operates from Estonia, as the Estonian-language version of its website and the user figures it publishes indicate. The provider states that its service meets eIDAS, GDPR, PSD2 and EBA requirements, but the website does not say where the service is hosted or operated. The shareholders of SK ID Solutions could not be confirmed from the pages reviewed and should be checked in the Estonian commercial register. For a European organisation, Smart-ID is an identity service from an EU provider, but its hosting location should still be confirmed with the provider.

Why digital sovereignty matters with Smart-ID

Smart-ID is headquartered in EE 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 Smart-ID scores best on data residency.

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