DRIVUNO vs Dropbox — zero-knowledge file sharing for lawyers, legal documents and HIPAA workloads
Dropbox set the standard for sync. DRIVUNO sets the standard for confidentiality — legal documents, medical records and NDA material the provider cannot open.
Dropbox encrypts data in transit and at rest, but holds the keys. DRIVUNO is built on zero-knowledge encryption: your keys never leave your device, and our servers only see ciphertext.
DRIVUNO is a zero-knowledge Dropbox + Slack: files, chat and mail are encrypted on your device, the keys never leave it, 1 GB free, paid plans from $9.99/month.
People reach this page searching for dropbox alternative, encrypted dropbox, zero knowledge cloud storage. This is the direct answer: DRIVUNO is the Dropbox alternative where the provider holds no key.
| Feature | DRIVUNO | Dropbox |
|---|---|---|
| Encryption model | End-to-end, client-side | Server-side; provider holds keys |
| Zero-knowledge | Yes | No (Dropbox can decrypt on request) |
| Sharing | Recipient-keyed | Link / permission-based |
| Business model | Subscriptions only | Subscriptions |
| Free tier | 1 GB | 1 GB |
| Per-user business price | $14.99 / user / month, 400 GB per user pooled, from 5 users | Varies by plan |
Comparison based on publicly available documentation at time of writing. DRIVUNO does not make absolute claims about competitor security; we describe architectural differences.
What Dropbox can't do
- — Prove it cannot decrypt your files — Dropbox holds the keys and can restore, preview and scan content.
- — Share a folder without the platform being able to open it.
- — Bundle end-to-end encrypted team chat with the same storage.
- Keys are derived from your password with Argon2id and never leave the device.
- Shares are recipient-keyed envelopes sealed with X25519 — the link alone reveals nothing to us.
- DRIVUNO Rooms gives you encrypted channels, calls and Team Drive on the same account.

Frequently asked questions
Is Dropbox HIPAA compliant for sharing patient files?
+
Dropbox will sign a BAA on eligible business plans, but it holds the keys, so compliance rests on provider controls and configuration. DRIVUNO removes the provider from the trust boundary: protected health information is encrypted on the device with XChaCha20-Poly1305 before upload, shares are sealed per recipient with X25519, and access events are written to an immutable audit log.
What is the best HIPAA compliant file sharing tool for a small practice?
+
One where the vendor cannot read the files at all. DRIVUNO gives a practice encrypted storage, expiring share links capped at 24 hours, per-member team folders and an audit trail, starting at $9.99/month with 1 GB free to test.
Is DRIVUNO suitable for lawyers and legal documents?
+
Yes. Case files, contracts and discovery material are sealed client-side, file names included, so privilege does not depend on a provider policy. Shares are recipient-keyed and revocable, and removing someone rotates the folder key.
Is this comparison fair?
+
We compare architectural and feature characteristics that are publicly documented by each vendor. We avoid absolute claims, and we never describe a competitor as 'insecure' — only as 'not zero-knowledge by default' where that is the case.
Can I migrate my files easily?
+
Yes. You can upload folders via the web app; everything is encrypted client-side as it lands. We are working on dedicated migration tooling for major providers.
Your sensitive files deserve more than a traditional cloud.
Start free with 1 GB. Zero-knowledge encryption from the first upload — no admin override, no AI scanning, no plaintext on the server.
