Summary

Hide ▲

Proton introduced Meet, a new end-to-end encrypted (E2EE) video conferencing platform designed to prioritize user privacy and regulatory compliance. Unlike mainstream services, Meet provides E2EE calls by default without requiring a paid plan or Proton account, supporting one-hour meetings for up to 50 participants at no cost. Longer sessions are available via a paid "pro" tier starting at $7.99/month. The platform integrates with Proton Calendar and supports third-party calendar systems such as Google and Microsoft. Meet is positioned as a response to growing privacy concerns, geopolitical instability, and the use of user conversations to train AI models. Proton emphasizes that Meet’s architecture uses Messaging Layer Security (MLS), an open-source, independently reviewed E2EE protocol, for real-time group communication. All media and chat are encrypted client-side, ensuring Proton cannot access or process cleartext data. Meet leverages WebRTC with Selective Forwarding Units (SFU) for media relay and employs the Secure Remote Password (SRP) protocol for participant authentication. Meeting links include client-side stored IDs and passwords, and the platform supports forward secrecy through epoch key rotation on join/leave events, preventing new members from reading past messages and old members from accessing future ones. The service omits logging of meeting associations and retains only meeting IDs in databases, minimizing exposure in case of a server compromise. Potential risks are limited to meeting link compromise, which can be mitigated through access controls and link rotation.

    Proton launches Meet with end-to-end encrypted, privacy-first video conferencing

    Proton introduced Meet, a new video conferencing platform offering default end-to-end encryption without requiring an account or payment. The service supports one-hour meetings for up to 50 participants at no cost and integrates with Proton Calendar and third-party calendars. Meet uses Messaging Layer Security (MLS) for group encryption, WebRTC with SFU for media routing, and SRP for authentication, with forward secrecy enforced via epoch key rotation. Server-side data retention is limited to meeting IDs, and meeting links include client-side stored credentials to reduce exposure risks.
