Vegas-S MIL-STD-1553 Data Diode

Combining a simplistic design in right-sized packaging, the Vegas-S data diode provides hardened security for the MIL-STD-1553 data bus.  Through one-directional data flow, Vegas-S acts as a physical firewall when integrated into the data bus.  With no microcontroller or microprocessor utilized in the design, Vegas-S is a plug-and-play device that cannot be exploited by cyber-attacks.  Protecting your system from untrusted bus monitors simplifies cyber assessment and authorization.
