Proton has launched Proton Meet, an encrypted video conferencing service built as an alternative to platforms such as Zoom, Google Meet, and Microsoft Teams. The new service focuses on end-to-end encryption for calls, messaging, and screen sharing, with support for both personal and business use.
The launch comes as video calls continue to replace in-person meetings across workplaces, schools, and households. While video conferencing has become routine, concerns about how platforms handle meeting content and metadata have grown.
Proton Meet end-to-end encrypted
Proton Meet secures calls using Messaging Layer Security, or MLS, an open-source encryption protocol that has been independently reviewed. The company says this approach ensures that only participants in a meeting can access audio, video, chat messages, and screen shares.
“With Proton Meet, every call is end-to-end encrypted, so not even Proton can access your audio, video, screen shares, or messages,” the company said in its announcement.

Meetings can be created without requiring users to sign in, allowing hosts to generate a call link and invite others directly. Participants can join through a browser without creating an account, which lowers barriers compared to services that require registration.
Screen sharing and real-time chat are included, allowing participants to collaborate during calls. Messages sent during meetings are encrypted in the same way as video and audio streams.
Calendar integration is also supported, allowing meeting links to be added to Proton Calendar as well as calendars from Google and Microsoft. Users can create scheduled sessions or generate links instantly for ad hoc calls.
Proton also raised concerns about how some video platforms process user data, particularly as companies expand AI features. Depending on platform policies, audio, video, or chat data could be used to train AI systems, creating risks that private conversations could be reused in future outputs.
Proton Meet is available now through a web-based interface. Free access supports meetings with up to 50 participants lasting up to one hour. For users who need longer sessions or additional business features, paid plans start at $7.99 per user per month.
