Who can access the conversation and the workspace
Qube vs Proton Meet
Proton Meet protects a private conversation. Qube protects the conversation and the work inside it. The shared computer, applications, files, delivered stream, participant context, and review evidence form one secured room.
Two products. Two different security boundaries.
Proton Meet security boundary
Proton Meet provides strong participant-to-participant privacy with MLS end-to-end encryption. It remains a conferencing product built around participant devices and ordinary screen sharing.
Qube protected cloud room
Qube secures the live working session. Participants operate one cloud computer while protected streaming, local-app isolation, context enforcement, environmental safeguards, and forensic evidence cover the endpoint boundary.
Compare the security boundary
Qube secures the meeting, shared computer, files, applications, delivered stream, and review evidence as one room. Proton Meet protects the capabilities documented in its product materials. The table makes the difference explicit.
| Capability | Qube | Proton Meet |
|---|---|---|
| End-to-end meeting encryption | Built into QubeQube encrypts live meeting media end to end with SFrame and rejects encrypted sessions when runtime authorization fails. | IncludedProton documents transport protection alongside participant-side encryption. |
| Protected meeting stream | Built into QubeQube delivers the meeting and shared workspace through a protected streaming path designed to block ordinary software capture on supported clients. | Not documentedThe product documentation does not show a native equivalent. |
| Local AI / app isolation | Built into QubeFiles, applications, and working state stay inside Qube’s cloud workspace, outside the participant’s local desktop and local AI tools. | Not documentedThe product documentation does not show a native equivalent. |
| No install | Built into QubeParticipants join Qube from a supported browser while the workspace stays in the cloud. | IncludedProton documents joining from a browser. |
| Context enforcement | Built into QubeQube monitors fullscreen and focus, covers or pauses protected content when the participant leaves the session, and records the event for review. | Not documentedThe product documentation does not show a native equivalent. |
| Watermarking & attribution | Built into QubeQube combines forensic watermarking with session identifiers so protected content can be traced to its meeting context. | Not documentedThe product documentation does not show a native equivalent. |
| Second-device surroundings view | Built into QubeQube pairs a second device to give the host a live view around the participant’s workstation. | Not documentedThe product documentation does not show a native equivalent. |
| Acoustic leakage detection | Built into QubeQube monitors for protected meeting audio leaking into the surrounding room and surfaces the signal as part of the session security record. | Not documentedThe product documentation does not show a native equivalent. |
| Layered identity defense | Built into QubeQube combines participant video, the protected workspace, a paired surroundings view, and security events to give reviewers more context than a conventional call. | Not documentedThe product documentation does not show a native equivalent. |
Qube protects more than the call
Encryption and trust
Proton uses MLS end-to-end encryption so only participants can decrypt call media. Qube uses application-layer encrypted meeting media inside a trusted cloud room and protects the decrypted output on supported devices.
Where the work runs
Proton shares screens from participant devices. Qube provides the meeting with its own computer, keeping files, applications, browser state, and approved tools inside the cloud room.
Recording and review
Qube preserves an authorized record of the conversation, workspace activity, and security events. Review access and retention remain controlled after the temporary computer closes.
Protect the work, not only the conversation
Proton keeps call media unreadable to its service. The files and applications discussed in that call still run on participant-controlled endpoints.
Qube moves the work into a trusted, secured cloud runtime. It protects the applications and files during execution, then protects what participants receive on supported devices.
Decide where the research will run
An unpublished research review needs more than private audio and video. Researchers inspect a model, open supporting material, test an input, and revise the same working file.
Qube keeps the research material and tools inside the cloud session. Participants operate them through protected streaming on supported clients.
Close the participant endpoint gap
End-to-end encryption stops network and service interception. Local capture software sees content after the participant decrypts it.
Qube protects that presentation path and adds a paired surroundings view, acoustic safeguards, and forensic watermarking around physical capture risks.
What teams ask about Qube
Is Qube’s cloud workspace the same as Proton’s E2EE?
Proton keeps call media readable only by participants. Qube secures a broader working session inside a trusted cloud runtime, including the applications, files, delivered pixels, participant context, and review record.
Does E2EE make a meeting invisible to local AI tools?
No. End-to-end encryption stops interception before decryption. Qube also protects the endpoint after decryption: protected streaming resists ordinary local software capture, and environmental safeguards cover the room around the participant.
Can participants join through a browser?
Yes. Proton documents browser access, and Qube participants also join through a supported browser. Qube negotiates the required protection as part of the joining flow.
