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
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 licence 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.

When this is the right fit
Any organisation that keeps sensitive or legally retained documents and can't afford a leak: professional services (law, tax, accounting, consulting), healthcare practices and clinics, financial and insurance offices — and any small or mid-sized business with contracts, HR files or financials.
