XD Guardian XML

Exportable Cross Domain Solution


XD Guardian XML is a dual-guard, quad-diode cross domain appliance that combines flexibility with low cost and high performance. The functional equivalent of Owl’s XD Bridge™ product, XD Guardian XML is the only exportable cross domain solution that has been assessed against the U.S. government’s most rigorous requirements for cross domain solutions.

XD Guardian XML supports both hardware enforced 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, XD Guardian XML can be easily deployed in enterprise applications or remote or isolated environments. Structured data filters are available for both file transfer and streaming protocols.
