DRIVUNO vs Signal
Signal secures conversations. DRIVUNO secures the whole project around them.
Signal is a reference implementation of end-to-end encrypted personal messaging, and we do not compete with it on that ground. The difference is scope: DRIVUNO Rooms is a work surface — organisations, channels with roles, an encrypted drive per channel, multi-gigabyte encrypted deliveries, expiring external links and continuous folder mirroring — with the same client-side key custody principle.
| Feature | DRIVUNO | Signal |
|---|---|---|
| End-to-end encryption | Yes, messages and files | Yes, messages and attachments |
| Identity | Work accounts (email), organisations and roles | Phone-number-centric accounts |
| Channels with roles | Viewer / creator / moderator / admin per channel | Groups and admins |
| Large file delivery | Multi-gigabyte, chunked and resumable | Attachment size limits |
| Encrypted storage behind the chat | Full drive, photos, Team Drive, versioning, trash | Not a storage product |
| External sharing | Expiring links with key in URL fragment | Not applicable |

Frequently asked questions
Is this comparison fair?
+
We compare architectural characteristics publicly documented by each vendor at the time of writing. We never call a competitor insecure — only 'not zero-knowledge by default' where that is the case.
What does zero-knowledge change for a chat tool?
+
Message payloads are sealed on the device under a room key wrapped per member. The provider relays envelopes it cannot open, so there is no admin export of content, no server-side scanning and nothing readable to disclose.
Do we lose features by encrypting everything?
+
You keep channels, threads, mentions, reactions, file drops, galleries, encrypted ZIP downloads, calls and search. Search runs on blind indexes computed on your device instead of server-side plaintext indexing.
How do we migrate a team?
+
Invite members by email; keys are generated on their first login and channel keys are sealed to each member. Files can be dragged in, or mirrored continuously from a local folder with Live Clone.
Your sensitive files deserve more than a traditional cloud.
