Data diode/ Cross Domain Solutions


Product: XD Guardian

XD Guardian

XD Guardian™ is a dual-guard, quad-diode cross domain appliance that combines flexibility with low cost and high performance. The functional equivalent of Tresys’ XD Bridge™ product, XD Guardian is the only exportable product that has been assessed against the U.S. government’s most rigorous requirements for cross domain solutions.
XD Guardian supports both unidirectional and bidirectional transfer modes ensuring fast, effective, and secure data transfer between systems of differing security levels.


With its standard 1U rack-mountable configuration and minimal administration requirements, the product can be easily deployed in enterprise applications or remote or isolated environments.
Filters are available for both file transfer and streaming protocols such as full-motion video.
