Consumer chat apps posed GDPR risks

The client's teams were using WhatsApp for internal communication — creating Shadow IT risks, no DPAs with Meta, and zero control over data retention or Subject Access Requests.

EU-hosted zero-knowledge architecture

A proprietary messaging ecosystem hosted exclusively within the EU. End-to-end encryption ensures the server never sees plaintext. Centralised user management with enforced retention policies and comprehensive audit logs.

feat: implement Signal Protocol via WebAssembly

Compiled C-level cryptography to WebAssembly for browser-native execution. All messages encrypted locally before transit over WebSockets.

Complete data sovereignty achieved

The organisation now has absolute control over all communications data. Full GDPR Article 5 & 32 compliance, sub-50ms message delivery, and zero data leakage to third-party cloud services.
