Data Diode SPAN TAP
Secure SPAN Links with Hardware-enforced Perimeter Protection
Maintain network integrity for industrial network monitoring without exposing additional risk from remote attacks, DDoS attacks, malware, ransomware from external networks.
Data Diodes SPAN TAPs provide network traffic for out-of-band monitoring, specifically designed not to send traffic back onto the network. These purpose-built network hardware devices enforce one-way data flow for SPAN links with physical hardware separation, guaranteeing protection of critical digital systems, such as industrial control systems (ICS), from inbound cyber threats.
Data diodes can be found most commonly in high security environments, such as federal defense and critical infrastructure, where they serve as connections between two or more networks of differing security classifications. This technology can be found at the industrial control level for such facilities as nuclear power plants, power generation and safety critical systems like railway networks.
