It's already May 2026, and 2027 is just 7 months away. The quantum computing threat is no longer a future concern — it's becoming a present reality. Current E2EE, while strong today, will not hold up against quantum attacks.
Proton has always been ahead of the curve when it comes to privacy. Upgrading to Quantum-Safe Encryption (Post-Quantum Cryptography) across all Proton products — Mail, Drive, Calendar, VPN, and Pass — before the end of 2026 would be a massive step forward.
NIST has already finalized post-quantum encryption standards. There's no reason to wait. If Proton acts now, it becomes the first major privacy platform to be fully quantum-safe — and that's a huge deal for the community.
The goal is simple: by the time 2027 arrives, every single Proton product should already be protected with quantum-safe encryption. Not in progress — done.
This is not just a feature request. It's about staying true to Proton's core promise of long-term privacy protection.
