Separation you can see
The connection state is set by the hardware, not by a policy that can change quietly.
Bardin Gate LightPhysical Layer 1 Isolation Switch
One computer, two networks, never both at once
Light is a compact switch that connects one computer or system to either a safe network or an unsafe one. It selects the path physically and never connects both at the same time.
The problem it solves
Some computers need to reach two networks of different trust: a maintenance laptop, an analysis workstation, a lab machine. A firewall rule, a VLAN or a second network card leaves both paths alive, and one configuration mistake is enough to join them. Light takes the choice out of software. Its common port is wired to one network at a time, and the other is physically disconnected.
- Three ports
- Safe, Common and Unsafe Ethernet.
- One path
- The common port is connected to the safe or the unsafe side, never both.
- Safe at power-up
- It always starts on the safe network.
- USB Type-C
- One cable powers it and controls it.
The unit
A small metal unit with three network ports, powered and controlled through a single USB Type-C cable.

No routing, bridging, filtering, inspection or address translation, so there is nothing in it to misconfigure or attack.
A predictable default
After any power cut it comes back on the safe network.
Simple control
Switch from an application on the connected computer or, on supported models, with the front-panel button.
