About ETHERGAP

EtherGap develops physical-layer network isolation systems designed to eliminate entire classes of cyber threats by controlling whether connections exist at all.

EtherGap provides hardware-based network air gap isolation for organizations that need stronger protection than software controls, firewall rules, or policy enforcement alone can provide. Real Layer 1 physical isolation—not so-called "logical" or "virtual" air gaps, which are easily defeated by attackers. EtherGap holds the US patent for automated Layer 1 air gap under microprocessor control using out of band signaling - US Patent 11425102

By opening and closing network paths at the physical layer, EtherGap allows critical systems, backups, private circuits, and sensitive data environments to remain disconnected until connectivity is explicitly required. EtherGap actually breaks the wires of the physical data layer - something malware, exploits, and remote attackers cannot bypass.

Protecting systems from attack using resources which are equally exposed to attack is a strategy on borrowed time.

Any system connected to the Internet has a finite time to compromisetc — which shrinks with every passing minute. As AI-assisted attacks and future quantum computing capabilities are brought to bear, tc is shrinking at an increasingly alarming rate.

True protection of critical network assets now requires disconnective isolation: the ability to physically remove protected systems from reachable network paths until connectivity is explicitly required.

EtherGap is one of the only methods of protecting assets with true Layer 1 disconnection isolation — a hardware-based physical break in the data path that software attacks cannot bypass.

Attackers cannot breach what they cannot reach.

EtherGap is the firewall of the future.

EtherGap is designed for environments where compromise, ransomware, uncontrolled connectivity, or operational disruption can create unacceptable risk.
