Proton launches Meet with end-to-end encrypted video calls
Summary
Proton launched Meet, a video conferencing service with client-side encryption for calls and chat using MLS. It supports up to 50 participants on the free plan and uses WebRTC, SFU relays, and SRP authentication.
Key points
- Proton says Meet encrypts media and chat client-side using Messaging Layer Security (MLS), which it describes as an independently reviewed, open-source protocol.
- The service uses WebRTC and Selective Forwarding Units to relay media and chat; meeting passwords remain on clients and participant authentication uses SRP.
- Proton says MLS rotates the group encryption key when participants join or leave, preventing new members from reading past messages and former members from reading future messages.
- The free plan supports meetings of up to 50 participants for one hour; a Pro plan for longer calls starts at $7.99 per month.
- Proton says servers store only meeting IDs and cannot read or modify call traffic; it identifies compromised meeting links as the main risk and recommends locking entry, removing rogue participants, or rotating links.
