Datasure SecuSign: sovereignty score and 8 European alternatives

SecuSign API Expert is an electronic signature API from Datasure, intended for software vendors and larger organisations that want to build signing into their own applications. The service is driven entirely through a documented API and can be passed on without its own branding (white label). It supports simple, advanced and qualified signatures, signing of PDFs or hashes, certificates per signer (one-time or long-term), remote identity verification, timestamps, key storage in HSMs, batch signing and automatic electronic seals.

Datasure is a French SARL headquartered in Pézenas, presented on its site as a trust service provider under eIDAS; no owner or parent company is named. According to the vendor, the service is hosted in France. For a European organisation this means signing data and evidence stay within the EU; the terms refer to processing in line with the GDPR. No self-hosting option is mentioned.

Why digital sovereignty matters with Datasure SecuSign

Datasure SecuSign 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 Datasure SecuSign scores best on data residency.

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