XTS® Diode One-Way Transfer 

BAE Systems’ XTS® Diode provides next-generation, RTB-compliant One-Way Transfer (OWT) data security in a compact, lightweight, and rugged device.
XTS® Diode is a next-generation One-Way Transfer (OWT) device and the first named Raise-The-Bar (RTB)-compliant by the National Cross Domain Strategy Management Office (NCDSMO) and the National Security Agency (NSA).

BAE Systems’ XTS® Diode is a small, lightweight, and rugged OWT device that enables secure, unidirectional transfer of data, email, and files between users on networks of different classification levels. It uses pitcher/catcher software combined with hardware enforcement, and integrates with NiFi or Datagate Orchestration engines for information validation to assure secure delivery. The pitcher/catcher software is hosted on our STOP™ high assurance operating system, or Red Hat Enterprise Linux (RHEL).

Providing agencies and users across various classification levels with the information security and cyber resiliency they need to communicate and collaborate effectively, XTS Diode already secures sensitive data for the Department of Defense (DoD), the intelligence community (IC), and coalition partners worldwide.

A perfect technology partner to our XTS® Guard 7 cross domain solution, XTS Diode can also be used with other CDS systems, it is OS-agnostic, and its advanced OWT architecture can bolster performance in any secure data system. That includes secure communications for state, federal, and municipal law enforcement, critical infrastructure systems, and approved commercial applications.

Key capabilities and benefits of the XTS® Diode include:

  • Meets all NSA and NCDSMO RTB cyber security requirements
  • More capabilities and speed compared to earlier OWT solutions, in a significantly more compact size and at lower unit, implementation, and maintenance costs.
  • Includes forward-error correction to ensure messages can be recovered post transmission.
  • Reaches 10Gb of throughput while maintaining a miniscule footprint,
  • Application options are predicated on STOP™ to heighten the level of security at the operating system level, as well as providing OS heterogeniality required by RTB
  • XTS Diode seamlessly integrates with the XTS® Guard to comply with the latest RTB architectures for deployment,
  • Simple API developed to enable the simple plug-in of numerous content filters,
  • Lower cost by allowing all products to be purchased and supported from a single vendor, with proven architecture and experience,
  • Perfect for sharing files, or streaming ISR via User Datagram Protocol (UDP) or Transmission Control Protocol (TCP)
