How Proton Meet keeps your video calls private
Proton Meet’s strong security features shield your most important conversations from eavesdropping, data breaches, and surveillance.
Built with security and privacy at the core
While other video conferencing apps can harvest your calls and train AI with your data, Proton Meet's built-in protections keep your information entirely under your control.
MLS end‑to‑end encryption
MLS (Messaging Layer Security) is a modern encryption standard designed for large‑scale communication. It gives Proton Meet end‑to‑end encryption while performing with the same speed and convenience as other enterprise video conferencing solutions. All audio, video, screenshares, and chats are encrypted on each participant's device and can only be decrypted by the participants.
Meeting authentication
Protection of personal information
Data minimization and no-log policy
Multi-layered defense
Created to keep you in control
Beyond our code, Meet's features let you tailor the level of privacy, visibility, and access for every secure video call you make – putting your privacy in your hands.
Background blur
Keep the focus on the conversation, not the surroundings. Background blur masks everything behind you, preventing any accidental visual leaks of private spaces.
Noise cancellation
Eliminate background chatter and ambient sounds in real time. Meet's noise cancellation option focuses in on your voice, protecting both your privacy and the meeting’s clarity.
Screen share
Present work and ideas while controlling exactly what participants see — a single tab, a window, or your entire screen — when using Proton Meet on web and desktop.
Host controls
Take charge of your meeting. Prevent new participants from joining, mute audio, stop video feeds, or remove attendees instantly with one-click controls.
Designed to protect, not exploit, your data
Proton Meet embodies our commitment to delivering simple, trustworthy alternatives to Big Tech platforms that prioritize profit over privacy.
Open source transparency
Every Proton Meet app is fully open source(new window), so independent researchers and the broader community can audit the code, verify the MLS implementation, and confirm that the protocol behaves exactly as described.
Secure and compliant
Proton is ISO 27001 certified and has SOC 2 Type II attestation. Proton Meet also complies with regulations such as GDPR, HIPAA, CJIS, and PCI, meeting the strict regulatory requirements of businesses worldwide.
Swiss privacy protection
Proton is headquartered in Switzerland, a country renowned for its strong privacy protections. All of our API and database servers are in our European data centers, outside of US jurisdiction and subjugation to US laws such as the CLOUD Act.
Confidential video calls for your most important meetings
Proton Workspace bundles Meet, Mail, Calendar, Drive, Docs, Sheets, VPN, Pass, and private AI into one encrypted suite — built for teams that need privacy by default. No ads, no data harvesting, no AI training.
