Restore engineering and control systems when the backup server is encrypted
When a destructive attack reaches your network, it does not stop at the production systems. It reaches the recovery systems too, because anything the network can touch is in scope, including the server you were counting on to bring everything back. In the Jaguar Land Rover incident, manufacturing across three countries stayed down for roughly five weeks, the estimated cost ran to about 1.9 billion pounds, and more than five thousand businesses in the supply chain felt it. If your last copy lives somewhere an attacker can reach, you do not really have a last copy.
For an operations team the clock is unforgiving. Every hour that engineering workstations, controllers and project files stay down is an hour of lost production, missed safety windows and contractual exposure. The recovery plan that looks complete on paper falls apart the moment the restore source is found encrypted alongside everything else.
Software based protection assumes the attacker can be held off by permissions, by immutability flags or by network segmentation. Each of those still runs on a control plane that the network can reach, which means each of them can be targeted by an intruder who already holds domain admin. Making data hard to change is not the same as making it impossible to reach.
A physically isolated recovery vault changes the model. Data moves into it across a one way path, so there is no route back in from the production side and nothing for an attacker to alter or destroy. There is no software attack surface to defeat, because the connection itself is removed rather than guarded. When your primary environment is down, the isolated copy is untouched, and it becomes the last resort source that brings engineering and control systems back.
Here is a test you can run without us. Ask your IT team to walk through a full recovery on the assumption that domain admin credentials are gone and the restore server itself is encrypted. If they can bring the line back in under four hours, you are in good shape. If they cannot, that gap is exactly what we close.
How do you restore OT systems when the backup server itself is encrypted?
If an attacker reaches your network, anything the network can reach is exposed, including the server you rely on to recover. A physically isolated recovery vault breaks that chain. Data moves into it across a one-way path, so there is no route back in from the production side and nothing for an attacker to alter or destroy. When your primary environment is down, the isolated copy is untouched.
Why is a physically isolated recovery vault different from an immutable backup?
Immutability makes data hard to change, but the control plane that manages it is still reachable over the network and can still be targeted. Physical isolation removes the reach entirely. The disk is not just un-editable, it is unreachable, and that difference is what holds up when domain admin credentials are gone and the systems you trusted to recover are themselves compromised.
