etherCUT - L1 physical level Ethernet breaker/switch for critical applications
etherCUT(ethernet+cut) - a hardware module designed for the physical breaking, segmentation, and switching of industrial Ethernet networks on the L1 physical level. It provides authorized personnel with secure, remote control over the physical layer of critical network infrastructure. etherCUT is intended for:
Key Applications:
- Operational Technology (OT) Cybersecurity: Isolate critical assets during cyber incidents to prevent threat propagation.
- Incident Response & Network Segmentation: Rapidly segment ICS/SCADA networks from enterprise IT in the event of a threat or breach.
- Secure Remote Access: Enable remote management of physical network architecture for industrial control systems (ICS) and facility networks, including via secure GSM connectivity.
- Controlled Network Switching: Function as a remote-controlled physical level switch for digital networks using Ethernet, RS-232/422/485 and CAN interfaces.
Technical Specifications:
- Supported Standards: Full compatibility with Ethernet 10/100/1000 BASE-T.
- Interface Support: Can also switch legacy digital interfaces (RS-232/422/485, CAN)
