FAQs

  • A hardware device that physically enforces one-way data flow. It’s designed to maintain secure communication between networks of differing trust levels.

  • A data diode enforces one-way communication at the hardware level. Firewalls and ACLs use software rules and can be misconfigured or exploited.

  • Yes, they’re commonly used in OT/ICS for secure segmentation between critical systems and external networks.

  • Yes, data diodes support compliance with these standards.

  • If properly implemented, data diodes are extremely difficult to bypass because they are physical hardware with no software interface to exploit. However, poor implementation or side-channel attacks could pose risks.

  • Our data diodes operate with <1 milliseconds latency and are engineered for high throughput in performance-critical environments.

  • No, true data diodes do not support bidirectional protocols like TCP. Workarounds involve using protocol breaks or proxy systems.
