QNAP Three-layer Defense Architecture

Snapshots, immutable storage, and physical isolation—three layers of defense working together to ensure your data can be safely recovered under any circumstances.
Layer 1: Snapshot Protection
Instantly create data snapshots to record the status at every moment. Locked snapshots cannot be deleted by ransomware.

Layer 2: Immutable Storage
Backup data is locked immediately after being written, and absolutely no one (including administrators) can modify or delete it.

Layer 3: Physical Isolation
Airgap+ achieves physical isolation through a QNAP Router or Switch, remaining completely offline under normal circumstances and only connecting temporarily during backup.

Real-World Case: The "Last Line of Defense" That Saved a U.S. Educational Institution
When attackers obtain the highest administrator privileges, what is truly the last line of defense to protect data?
A U.S. educational institution's systems were paralyzed when attackers stole high-level credentials via phishing. Traditional defenses failed to stop these "legitimate" logins, resulting in encrypted data.
Fortunately, QNAP’s Immutable Storage (QuObjects Object Lock) protected their backups from being deleted or encrypted. The institution quickly restored its systems without paying any ransom.
