How Our Products Work

Owl data diodes can perform a data transfer in three different scenarios:


Data diodes enable a secured network to send data one-way out to external users and systems that need it. The send side emits light (aka data) to a photo receiver on the destination side. It’s like a one-way valve for data—on tap whenever you need it, with no entry back in.


Data diodes can also be used to transfer data, such as software updates and executables one-way into a secured network. Optional filtering and anti-virus keeps dangerous files from entering and hackers have no visibility into the network.


Some systems cannot operate one-way, so they require a two-way solution. For these use cases, Owl has unique bidirectional data diode solutions that operate on two parallel one-way paths. Get all the security advantages of data diodes with the flexibility of a two-way solution.
