DRIVUNO vs Amazon S3
S3 is infrastructure. DRIVUNO is the confidential product you would otherwise have to build on top of it.
S3 is superb infrastructure with server-side encryption managed by AWS keys (or your KMS keys, still inside AWS). Using it privately means building client-side encryption, key wrapping, sharing, previews, versioning and a UI yourself. DRIVUNO ships all of that: Argon2id-derived keys, per-file XChaCha20-Poly1305 encryption, X25519 sharing envelopes, encrypted previews, version history and Live Clone continuous mirroring.
| Feature | DRIVUNO | Amazon S3 / AWS |
|---|---|---|
| Encryption keys | Derived on your device, never sent | SSE-S3 / SSE-KMS, keys inside AWS |
| Provider can decrypt | No | Yes, unless you build client-side encryption |
| Ready-to-use interface | Drive, photos, mailbox, teams | Console and APIs |
| Continuous folder mirroring (Live Clone) | Yes — live 24/7, encrypted on device, version history | Build it with the CLI / SDK |
| Sharing model | Recipient-keyed envelopes, ≤24 h public links | Pre-signed URLs, IAM policies |
| Pricing model | Flat plans, no egress surprises | Per-GB storage, requests and egress |

Frequently asked questions
Is this comparison fair?
+
We compare architectural and feature characteristics that are publicly documented by each vendor at the time of writing. We never describe a competitor as 'insecure' — only as 'not zero-knowledge by default' where that is the case.
What does zero-knowledge change in practice?
+
Your files are encrypted on your device with keys derived from your passphrase (Argon2id) before upload. DRIVUNO stores ciphertext and wrapped keys only, so there is no admin override, no content scanning, and nothing readable to disclose under legal pressure.
Can I mirror my computer folders continuously?
+
Yes. Live Clone watches one folder, several folders or a whole external disk on PC or Mac and clones every change to your vault in real time, encrypted on your device, with version history retained.
Can I migrate my existing files?
+
Yes. Upload folders through the web app — everything is encrypted client-side as it lands — or point Live Clone at the local copy of your current cloud folder and let it mirror itself.
How do I start?
+
Create a free account with 1 GB, encrypt your first upload in under a minute, and upgrade only when you need the space.
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.
