WISeKey: sovereignty score and 8 European alternatives

WISeKey is a Geneva-headquartered group that supplies public key infrastructure (PKI) software, digital identity services and trust services under ETSI standards. Its CertifyID suite includes root and issuing certificate authority software and TLS certificate management. The group also develops post-quantum cryptography and secure chips, which its listed subsidiary SEALSQ sells. The parent company is listed on SIX Swiss Exchange and on Nasdaq.

WISeKey was founded in 1999 and is headquartered in Geneva, Switzerland. Switzerland is outside the EU, but the EU considers it to provide adequate data protection. The privacy notice states that processing takes place mainly in Switzerland or in EU countries. The notice dates from 2018, so current hosting arrangements should be confirmed with the company. The website describes the trust anchor as held in Switzerland under Swiss jurisdiction. The majority shareholder is not named on the website, and the software is proprietary rather than open source.

Why digital sovereignty matters with WISeKey

WISeKey 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.

WISeKey hosts data in the EU and in Switzerland. Switzerland is covered by a European Commission adequacy decision, so personal data can go there without extra safeguards. If you require strictly EU hosting, check the data processing agreement for which data is stored in Switzerland.

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