As data diodes became more common in commercial markets, competition introduced confusion about what truly defines a data diode and how it differs from similar solutions such as unidirectional gateways. This document clarifies key distinctions, emphasizing that Owl data diodes are designed from the ground up to be strictly one‑way, using intentional one‑way techniques rather than modified or disabled two‑way methods. Owl products are delivered in a true single‑box, hardware‑based format that offers very high reliability, extremely low latency, and a long expected lifespan of over 11 years. Founded in 1999, Owl was the first company to bring a data diode to market and holds more than 28 patents supporting its technology.
