Multiple Operating Systems - Windows, Linux, and Mac OS are all supported with no additional software installation. (Driver is required when multiple displays are connected to a single PC.) Active tampering system Unidirectional Optical Data Diodes assure data can only flow from devices to host Hardware based peripheral protection - eliminates data leaks with hardware-controlled unidirectional data flows that allow the primary input devices (keyboard/mice, etc.) to communicate in only one direction, preventing data from flowing back to the input devices for enhanced security.
