Owl Cyber Defense specializes in data diode hardware technology that allows for secure, one-way data transfer while providing absolute network segmentation, assuring network security against malware and control system override, as well as defending against other risks. While OPDS data diodes enforce network segmentation and eliminate the risk of penetration, a complementary software layer is required in order to manage the device, enforce security, interact with the network and control data flow. Owl Talon^TM is the software layer that operates the device, manages data flows and protocols while allowing the data diode to interact with endpoints on the network. Built on a defense-in-depth strategy, the OPDS hardware and Talon software operate together in a layered approach to defend both the network and hardware from cyber attacks.
