Overview
Encrypted backup that only you can open
SaQura Tresor is a zero-knowledge, end-to-end encrypted backup for businesses that handle confidential documents. Your files are encrypted on your own device before they ever leave it, so no one but you can read them. Not us. Not anyone.
Overview
Whoever holds your data can read it
Ordinary cloud backups hand your files to a third party who technically can read them, and who becomes a single, attractive target for attackers. For regulated businesses that's a compliance and trust problem. SaQura Tresor removes it entirely: the storage side only ever sees unreadable, encrypted data.
What it is
Only you hold the key
Files are encrypted on your device with keys that never leave it; the storage side holds only encrypted data plus minimal, non-identifying metadata. Backups are immutable and versioned, with two-factor authentication and per-device activation. Every relevant action is recorded in an append-only, cryptographically chained audit trail with qualified timestamps, so you can prove what happened and when. Designed around EU data protection (GDPR) and German record-keeping (GoBD).

Proof, on a single page
Auditor at the door? Tresor makes a one-page report at the push of a button: who owns the vault, the license status, what happened and when, and, at the bottom, a tamper-check that simply reads “OK”. No jargon. Here's a real example you can open.
