DRIVUNO vs Microsoft Teams
Tenant-managed keys protect you from outsiders. Client-side keys also protect you from the platform.
Microsoft Teams is deeply integrated with Microsoft 365 governance, eDiscovery and retention — features that exist precisely because the platform can read content (end-to-end encryption is limited to specific one-to-one calls). DRIVUNO Rooms takes the opposite position: content is unreadable to the provider, and governance is handled through membership, key rotation and immutable security logs.
| Feature | DRIVUNO | Microsoft Teams |
|---|---|---|
| Encryption model | End-to-end for messages and files | Service/tenant-managed keys; E2EE limited to some 1:1 calls |
| eDiscovery of content | Not possible on the provider side | Supported by design |
| File names and structure | Encrypted, searched via blind indexes | Visible to the platform (SharePoint/OneDrive) |
| Files inside conversations | Encrypted before upload, client-side previews, encrypted ZIP download | SharePoint-backed, provider-readable |
| Deployment | Browser and PWA, nothing to install | Desktop/mobile clients, tenant administration |
| Departing member | Sealed keys revoked and rotated | Account disabled; content remains in the tenant |
| Continuous folder mirroring | Live Clone, encrypted on device, version history | OneDrive sync (provider-readable) |

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.
