Who can access the conversation and the workspace
Qube vs Proton Meet
Proton Meet focuses on keeping call content private between participants. Qube focuses on a controlled cloud room where the conversation and shared work happen. The right choice starts with whom you trust and what you need to protect.

When Proton Meet fits
Evaluate Proton Meet when participant-side encryption and confidentiality from the meeting provider are central requirements. Its published design keeps the meeting’s content encrypted between participants.
When to evaluate Qube
Evaluate Qube when the participants need a shared cloud computer and you accept the Qube runtime as a trusted component. Validate the presentation controls against your local-capture threat model.
Compare the controls and their conditions
A documented feature, an operating condition, and a measured result are different evidence. “Not established” means the reviewed sources did not establish an equivalent; it does not prove absence.
| Capability | Qube | Proton Meet |

Encryption and trust
Proton describes MLS-based encryption of meeting content on participant devices. Qube’s cloud runtime processes the work and is trusted by its threat model. These are different promises; protected output must not be represented as provider-blind E2EE.
Where the work runs
Qube’s computer provides a common execution environment for files and tools. Decide whether you need that environment or a private call around tools running elsewhere.
Recording and review
Decide whether the meeting should leave an authorized review record at all. Evaluate each product’s current recording behavior separately; do not assume encrypted call content and server-side review records have identical trust requirements.
Start with who may process the content
A private conversation may need to stay unreadable to the conferencing provider. A shared working session may instead require a trusted cloud service to run applications and collect an authorized record. Neither requirement should be hidden behind the word secure.
If confidentiality from the service itself is mandatory, evaluate that requirement explicitly. Qube’s architecture assumes trust in its cloud control plane and session runtime; this comparison does not claim to remove that trust.
Decide where the research will run
For an unpublished research discussion, a team might only need to talk privately. Another team may need to inspect a model, browse supporting material, and work on a shared file. Those are different meeting designs.
Inside Qube, suitable working material and tools can stay in the cloud session while participants interact with them. The protection of what they see and hear depends on the actual delivery path and supported clients.
Treat the participant’s device as a separate boundary
Participant-side encryption protects confidentiality across the service and network boundary. It does not, by itself, establish that software or a physical camera on a participant’s side cannot capture content after it is presented.
A Qube evaluation should test supported presentation controls rather than rely on a general encryption label. External cameras, microphones, and human disclosure remain relevant whichever product you choose.
Questions before the meeting
Is Qube’s cloud workspace the same as Proton’s E2EE?
No. Proton describes content encrypted between participant devices. Qube relies on a trusted cloud runtime to run the shared environment. Choose according to the actual trust boundary you require.
Does E2EE make a meeting invisible to local AI tools?
That does not follow from E2EE alone. Encryption and local capture are different boundaries. Check the client’s presentation path, audio behavior, and any additional controls before making a capture-protection claim.
Can participants join through a browser?
Proton documents browser access, and Qube’s normal joining flow also uses a browser. For Qube, the desired protection must still be supported on that browser, operating system, and device.
