Secure meeting platform

The secure meeting platform that says what it can't do — and makes leaks traceable.

Most "secure" meeting tools mean encryption in transit and a visible watermark. Supermeet's secure mode means the join is attested, screen capture is blocked where the operating system allows it (Android) and detected and blacked out on iPhone and iPad, and what each participant sees carries an invisible mark that points to their account — through a reviewed leak case, not a guess.

Why Supermeet

What "secure" means here, precisely.

Attested, app-only joins

Browsers never get a secure session. Play Integrity on Android and App Attest on iPhone, iPad and Macs with macOS 27 or later prove the app; the per-session key is handed only to that join, and Supermeet can force an app update for secure sessions.

Capture blocked where the OS allows

Android blocks screenshots and screen recordings. iOS cannot block recording, so on iPhone and iPad the app detects recording and mirroring and ends the secure meeting on that device; screenshots there are not blocked but carry the mark. On a Mac, screen recorders can capture the window, so the mark does the work.

The invisible mark

A forensic mark drawn on each participant's own device, unique to them, with a pattern that changes every ten minutes. Drawing it has a 4 ms per-frame budget: 2.6 ms median measured at 1080p on an Apple M3 Max; phones are not yet measured.

Everyone's view is theirs

Each participant's screen carries their own mark — hosts included — so a leak points to one account, not to "someone in the room".

Leak cases with review

The extraction service reports match, probable or no match; a person who did not open the case reviews it before anyone is named; every step is logged; the participant can appeal through Supermeet.

Recordings on your retention policy

Cloud recordings are kept in Supermeet's storage for your retention period (default 12 months), with a 48-hour email before erasure; Secure classes replay only inside the app, with each viewer's mark.

How it works

How a secure session runs.

01 · CHOOSE

Start a secure session

A secure meeting or a Secure class is app-only and leak-traceable; participants join from the Supermeet app.

02 · NOTICE

Participants are told

The apps tell participants, in English or Hindi, that what they see is marked to their account; the full secure-session notice is published.

03 · CASE

If something leaks, open a case

Upload the clip; the extraction service reports match, probable or no match; a person who did not open the case reviews it; the participant can appeal.

Who secure sessions are for

  • Boards and finance: results, fee structures, M&A, audit committees.
  • Legal: privileged calls, depositions, settlement discussions.
  • Product and design: unreleased work shown on screen.
  • Education and paid content: question papers, paid courses, exam-prep classes.
  • HR and medical: interviews, sensitive consultations.

Tested, and what is still to test

In tests on synthetic video, the mark survived messaging-app-quality re-encodes down to 240p, a crop and a simulated camera angle. Tests with real classroom footage and a real camera are still to run. Full details and limits →

Honest limits. A rooted or jailbroken device, a modified app, a Mac screen recorder or a phone camera can still capture a session. The mark is what traces such a copy — attribution, not prevention, is the aim — and it has been tested on synthetic video, not yet with a real camera.

Questions

Frequently asked

Is a secure meeting end-to-end encrypted?
No. Media is encrypted in transit and per-session keys protect secure playback, but Supermeet does not offer end-to-end encryption. Secure mode is about who can join, what devices can capture, and tracing leaks — different problems from server-side access.
Can participants join a secure meeting from a browser?
No, by design. Secure sessions run only in attested apps: Android 8 or later, iPhone and iPad with iOS 16 or later, and Macs with Apple silicon on macOS 27 or later.
What does a participant see?
The app tells them, in English or Hindi, that what they see is marked to their account. The full secure-session notice is published in both languages.
What does a leak case cost?
Leak cases are included with secure sessions.
How large can a secure session be?
Secure meetings hold up to 100 participants; larger secure audiences run as Secure live classes on the broadcast path, for up to 10,000 learners, with app-only join and each learner's own mark.
