Sharekey: sovereignty score and 8 European alternatives

Sharekey is a collaboration app for confidential business communication, made by SHAREKEY Swiss AG in Zug, Switzerland. It combines chat in dedicated channels, audio and video calls, document storage and file sharing with access roles. According to the vendor, it is aimed at executives, board members and legal and financial staff, and runs as mobile apps, a desktop app and a web version with history synchronised across devices.

The vendor describes app-to-app encryption with decentralised keys, so that it cannot read customer data; this is its own claim. The company is headquartered in Switzerland, which is not an EU member but an EFTA country with an EU adequacy decision, and states that its shareholders are Swiss and European. Encrypted data is stored in Swiss cloud storage and the vendor states GDPR compliance. No self-hosted edition or open-source licence is mentioned, so ask about key management and contract terms.

Why digital sovereignty matters with Sharekey

Sharekey 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.

Sharekey 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.

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