The VS‑Diode is a hardware‑enforced data diode solution designed to ensure strictly one‑way data transfer between networks with different security classifications. It physically prevents any reverse communication path, thereby eliminating entire classes of cyber attacks that rely on bidirectional network access. The solution is used where maximum separation between secure and less secure networks is required, such as in critical infrastructures, industrial control systems, and classified environments. The VS‑Diode enables controlled data export while maintaining the integrity and isolation of protected systems.
