Swisscom Trust Services: sovereignty score and 8 European alternatives

Swisscom Trust Services provides qualified and advanced electronic signatures for Swiss and European business processes. Its repetitive e-signing product for Switzerland requires a one-time identity verification; after that, the signer registers an approval method and can sign repeatedly within a set period. The service runs on an embedded platform that partners integrate into their own applications. Only a hash value of each document is sent, so the provider does not access the document contents.

Swisscom Trust Services is part of Swisscom, which is headquartered in Worblaufen, Ittigen, near Bern, Switzerland. The Swiss Confederation is the majority shareholder. The product page states that digital identities used for signatures are processed in georedundant data centres in Switzerland. The service is designed to meet both the Swiss ZertES Act and the EU eIDAS Regulation. For a European organisation, the relevant points are that the provider and its identity processing are Swiss rather than EU-based. Qualified signatures are recognised under eIDAS, and a processing location is stated for identity data, but not for all other service data.

Why digital sovereignty matters with Swisscom Trust Services

Swisscom Trust Services is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

Swisscom Trust Services hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

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