Wire
Swiss end-to-end encrypted messaging and collaboration platform for enterprise and government use. Backed by Schwarz Group (Lidl/Kaufland), hosted in the EU, and used by security-conscious organisations across Europe.
Quick facts
It's built for organisations that need real compliance and audit trails, not just casual chat, and the encryption protocol has been independently reviewed by academic cryptographers.
The interface is more enterprise-oriented than consumer messaging apps like Signal, and the free tier is limited if you want the full collaboration feature set.
Why does it score 82?
Incorporated in Zug, Switzerland – an EFTA country rather than a full EU member state.
Backed by venture investors and a strategic partnership with the Schwarz Group, though no single non-EU company holds a controlling stake.
Wire's infrastructure is hosted in Germany rather than a US-based cloud provider.
Fully open source and GDPR-compliant – used by governments and security-conscious organisations, a strong trust signal.
