Oakdoor designs and manufactures network security devices called data diodes, which are critical components of a cross-domain solution.
Cross-domain solutions are used where data needs to be transmitted between networks of differing trust levels while retaining high assurance of its confidentiality, integrity and availability. Oakdoor data diodes not only physically enforce a one-way flow of data, but can also provide security-enforcing functions such as syntactic verification of the data passing through the diode.
