How VS3 Works

Enterprise cloud storage, redesigned from the ground up.

VS3 replaces centralized cloud storage with a distributed, on-premises architecture that gives enterprises real data ownership, built-in compliance and verifiable integrity.

Storage Architecture

On-premises servers.
No third-party cloud.

VS3 stores encrypted data across Vautra's own on-premises server infrastructure. There is no AWS, no GCP, no Azure. Your data does not touch a third-party cloud layer at any point.

Data is distributed across multiple instances within your selected sovereignty region. During cross-instance replication, data remains encrypted end-to-end — plaintext is never exposed.

United States — multi-instance regional cluster
Canada — multi-instance regional cluster
Europe — multi-instance regional cluster
Data never crosses borders without your instruction

Encryption

Two layers of encryption.
One key you can keep to yourself.

VS3 uses a hierarchical key architecture. Every file gets a unique File Key, encrypted by a Project Key. You choose who holds the Project Key.

Vautra Managed Keys

Convenient for enterprise teams. Your Project Key is stored securely in a regional HashiCorp Vault instance within your selected sovereignty region.

Access-controlled per team member
Key never leaves your sovereignty region

User Managed Keys

Zero-Knowledge

Encryption happens in your browser before the file is sent. Your Project Key never reaches Vautra's servers. We cannot decrypt your files.

Encryption performed client-side in browser
Project Key held entirely by you
Vautra has zero access to plaintext

Audit Trail & Integrity

Every action recorded.
Every proof verifiable.

VS3 records every file action — upload, access, share, modification and deletion — in a real-time audit log.

Object proofs for every action are stored on Anryton, creating a tamper-proof verification layer that cannot be altered, even by Vautra.
