Developed and patented by Seclab, it removes layers 1 to 4 of the OSI model between the two networks: no TCP\/IP stack crosses the system. Only the useful data (files or application data) is transmitted from one side to the other via a non-routable electronic bus.<\/p>\n<p style=\"font-weight: 400;\"><strong>How does it work in practice?<\/strong><br \/>\nThe architecture relies on three independent processors, each dedicated to a distinct security function. Two separate access controls\u2014one for incoming traffic, one for outgoing\u2014enforce security policies that must be consistent with each other. The useful data is analyzed during transit (protocol verification, file signature checks, anti-malware scanning) before being reconstructed on the destination network.<\/p>\n<p style=\"font-weight: 400;\"><strong>How it differs from traditional filtering devices<\/strong><\/p>\n<ul style=\"font-weight: 400;\">\n<li>Protected assets are <strong>invisible and inaccessible<\/strong> from the at-risk network\u2014there is no network route to exploit.<\/li>\n<li>The attack surface is reduced by design, not by configuration.<\/li>\n<li>The system is <strong>resilient to its own compromise<\/strong>: even if a processor is compromised, the compartmentalized architecture prevents propagation.<\/li>\n<\/ul>\n<p>Electronic AirGap is CSPN-certified by ANSSI. It is installed between two networks without modifying the existing architecture, making it particularly suitable for OT environments (energy, transportation, industry, defense, telecom, water and waste) where availability is critical and maintenance windows are limited.<\/p>\n<blockquote style=\"background-color: #f0f0f0; color: #1a1a1a; border-left: 4px solid #cccccc; padding: 1em 1.25em; margin: 1.5em 0; font-size: 20px;\"><p><strong>Key takeaway<\/strong> &#8211; Electronic AirGap physically removes network connectivity between two zones through electronics.
