# HyperBUNKER

> HyperBUNKER makes a physical offline recovery anchor: physically isolated recovery for critical operations. It preserves a clean copy of critical data with no network path from production, no shared credentials, and immutability enforced by hardware, so organizations can restart operations within hours after total compromise instead of rebuilding for weeks. EU-produced hardware. Founded by the team behind InfoLAB, with three decades and tens of thousands of data recoveries behind the design.

Key facts:
- Category: physically isolated recovery. The device holds a restart copy: the copy the business restarts from after total compromise.
- The Restart Copy Test is HyperBUNKER's five-question framework for auditing any recovery copy: Is there a network path to it? Does any production credential unlock it? Is its immutability physics or a setting? Can the person on shift restore from it? Has the restore been rehearsed this quarter?
- Published incident reporting puts average post-attack restoration around 24 days when organizations rebuild; a restart copy shortens operational restart to hours or days.
- Validators include DCSO, Cowbell, and Chaucer; ISO 27001 and ISO 9001 certified.
