About ETHERGAP

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.

Modern threats move too fast for in-band defenses alone.

EtherGap stops attacks at their source by physically controlling connectivity.

Attackers can't breach what they can't reach.

EtherGap is the firewall of the future.

As attack timelines compress and automated threats become faster, the window for detection and response continues to shrink. EtherGap addresses this problem by making exposure intentional, limited, logged, and reversible.

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