Side-by-side comparison of Microsoft Teams and DRIVUNO on encryption model, key custody, admin access, search, offboarding and file handling.

Three private surfaces. Same zero-knowledge architecture.
The one-line difference Teams protects your content from outsiders while remaining readable to the platform, because governance features depend on that. DRIVUNO makes content unreadable to the platform, and handles governance through membership, key rotation and metadata-only audit logs.
Comparison table
| Criterion | Microsoft Teams | DRIVUNO |
|---|---|---|
| Encryption of messages | In transit and at rest, service-managed keys | End-to-end, sealed on the device |
| End-to-end coverage | Specific one-to-one call scenarios | Messages, attachments, files, mail, calls |
| Key custody | Service-managed within Microsoft key management | Derived on your device with Argon2id; never transmitted usable |
| Admin content export | Available through compliance tooling | Not possible — no key on our side |
| Search | Server-side index over content | Blind-index HMAC computed on device |
| File storage | SharePoint/OneDrive, server-readable | Encrypted drive, client-side previews |
| Member removal | Access revoked | Access revoked and keys rotated |
| Public links | Configurable, org-managed | Passphrase-gated, expiry within 24 hours maximum |
| Password reset restores data | Yes | No — by design; recovery kit required |
Where Teams is the better choice - You are required to run tenant-wide compliance search over message content. - Your workflows depend on deep Microsoft 365 and Copilot integration. - Your risk model treats the platform as trusted infrastructure.
Say this plainly to your stakeholders. A migration justified on false premises fails at the first audit question.
Where DRIVUNO is the better choice - Conversations that would cause commercial, legal or personal harm if disclosed. - Work under NDA, privilege or professional secrecy. - Teams that need to demonstrate that disclosure is technically impossible, not merely prohibited. - Organisations that want chat and a real encrypted drive under a single key model rather than two disconnected products.
What the daily experience looks like Channels, threads, mentions, reactions, pinned messages, tasks, file drops with client-side previews, encrypted ZIP downloads, galleries, calls with screen sharing, and a searchable encrypted mailbox. Team Drive folders hold a folder key sealed to each member individually. Live Clone mirrors a local folder continuously, encrypting before it leaves the machine.
Migration in practice Invite members by email; their keys are generated at first login and channel keys are sealed to them by an existing member. Bring history in through the universal importer for common export formats, drag files into the drive, and keep Teams for the non-confidential surface while you transition. Nothing forces a single cut-over date.
