-
XD Bridge comes with two physically different, factory-built configurations: unidirectional or bidirectional operation
- Features best-in-class performance with 1 Gb network interfaces delivering high throughput, low latency data transfer
The most cost-effective cross domain solution (CDS) in the market today, XD Bridge is available in a standard 1U 19″ rack-mountable configuration for use in enterprise applications or in remote or isolated environments. Depending on your application requirements, multiple tactical form factors are also possible.

Flexible Filtering
Filters are available for both file transfer and streaming protocols such as full-motion video.
The XD Bridge file transfer filter can perform:
- File type whitelist/blacklist
- Antivirus scanning
- XML schema validation
To meet unique requirements, the product’s design enables rapid development of data-filtering capabilities, including custom security policies and filters. In addition, Owl offers a two-day filter development course that enables customers or integrators to easily develop custom filters.
XD Bridge™ provides a flexible, modular platform for deploying cross domain data transfer filters. Certified filters exist for file transfer and streaming applications. The architecture allows additional special purpose filters to be developed and deployed as requirements evolve.
