Three private surfaces. Same zero-knowledge architecture.
Privacy has a technical definition A product is private, in the sense that matters here, when the provider cannot read your content even if it wanted to, was breached, or was compelled. Everything else is a policy commitment — valuable, but revocable.
Comparison
| Criterion | Google Chat | Encrypted team messaging |
|---|---|---|
| Encryption | In transit and at rest, provider keys | End-to-end, keys on the device |
| Provider can read content | Technically yes | No |
| Admin export of messages | Yes, through Workspace tooling | Not possible |
| Search | Server-side index | Blind index computed on device |
| Attachments | Provider-managed storage | Encrypted before upload |
| Member removal | Permission revoked | Keys rotated |
| Password reset restores history | Yes | No |
| Content scanning / AI on your data | Server-side capability exists | Only on your device, if at all |
Where Google Chat wins Frictionless integration with Workspace, calendar, meetings and documents. Central administration that most IT teams already know. Retention and investigation tooling if you are obliged to run it.
Where encrypted messaging wins Any conversation whose disclosure would be materially harmful: client work, deal terms, medical or legal detail, security incidents, unreleased product. Also anywhere you must be able to state, in a questionnaire, that the vendor cannot access content.
The false compromise to avoid "Encrypted with customer-managed keys" is not end-to-end if the service still decrypts content to index or preview it. Ask specifically whether plaintext exists in provider memory during normal operation. Usually it does, because features require it.
What good looks like in practice Channels and threads that feel ordinary; messages sealed under a per-room key wrapped to each member; local blind-index search that still finds a message from six months ago; attachments encrypted on the device with previews rendered locally; calls peer-to-peer; external sharing through passphrase-gated links with a hard 24-hour maximum lifetime; key rotation when someone leaves.
That is the shape of DRIVUNO Rooms, and the reason it ships with a full encrypted drive rather than chat alone.
