“Physically Enforced Unidirectional Data Transfer for High-Security Networks”

Arbit Data Diode is a Cross Domain Security solution designed to provide physically enforced unidirectional data transfer between networks with different security levels. Particularly suited for air-gapped networks, critical infrastructures, defence systems, and high-security networks, it enables required data to be transferred into secure environments while physically preventing communication in the opposite direction.

Physically Enforced Unidirectional Data Transfer: Arbit Data Diode ensures that data can only travel in the designated direction through its unidirectional fibre-optic communication architecture. The absence of a physical communication channel in the reverse direction helps prevent unauthorized data transfers from high-security networks.

Air-Gapped Network Security: The solution preserves the security level of air-gapped and isolated networks while enabling operationally required data to be securely transferred into protected environments. This helps reduce the operational challenges associated with maintaining completely disconnected critical systems.

Data Leakage Prevention: The physically enforced unidirectional communication architecture prevents data from being transmitted back from the critical network to the source network, helping to reduce the risk of data leakage. This provides a strong security layer against the unauthorized transfer of sensitive and critical information to lower-security networks.

Hardware-Enforced Security: With Arbit Data Diode, the direction of data flow is not controlled solely through firewall rules, software policies, or network configurations. Because unidirectional communication is enforced by the physical architecture, it establishes a hardware-based security boundary for protecting critical networks.

Protection of Critical Systems: Designed for critical infrastructures, defence systems, government networks, and high-security operational environments, Arbit Data Diode enables required data to be received from lower-security networks while helping preserve the isolation of critical systems.

Secure and Controlled Data Flow: Arbit Data Diode supports organizational requirements for network isolation, secure data transfer, data leakage prevention, and attack surface reduction. This enables organizations to maintain a strong balance between protecting high-security networks and sustaining the data flows required for critical operations.
