Electronic AirGap USB is a hardware device patented by Seclab that creates a complete physical break between a USB device and the protected system. The device is never connected directly to the critical system port—security relies on electronics, not software.

A fundamental principle: the device never touches the system

Unlike software-based USB port control (GPO, endpoint agents), Seclab Xport physically sits between the device and the host system. The USB device connects to the Seclab device, which analyzes and filters files according to the defined security policy. The protected system interacts only with a virtual USB drive presented by Xport, containing exclusively authorized files.

Why physical isolation outperforms software control

Software-based controls (antivirus, USB agents, application whitelisting) can be bypassed, disabled, or rendered obsolete by zero-day vulnerabilities. Physical isolation eliminates these risks by design: no direct communication is possible between the device and the system, regardless of the host software state. Protection does not degrade over time and does not depend on updates.

Key takeaway — Seclab Xport ensures electronic isolation of the USB port: the device never has access to the protected system. Only files authorized by the security policy are presented to the system via a virtual USB drive.
