XD Air 4.2 Assured Airgap Transfer Solution

This latest version of XD Air is a milestone in that it is the first wholly-independent release of the product...The result is an assured airgap solution with nearly all new features driven by actual customer usage.

Tresys Technology, a provider of technology and engineering services for customers with high-security requirements, today announced the company has made Tresys XD AirTM version 4.2 generally available. All recent product enhancements are the direct result of requests and requirements made to Tresys by new and existing customers in the Department of Defense (DoD), Intelligence, and Critical Infrastructure communities.

XD Air, a kiosk-based appliance, cleanses files on portable media to mitigate the risk that a device has for introducing malicious content into a network while shielding the inspection platform from modification. XD Air is also instrumental in inspecting—and aiding in the prevention of—sensitive or classified data content leaving a facility. Recent global events such as Buckshot Yankee, Stuxnet, and the WikiLeaks exfiltration have highlighted the vulnerabilities that high-security operating environments face, causing organizations to seek threat vector mitigation capabilities to reduce their exposure.

XD Air enforces the only operating policy that can protect an environment from Zero-Day malware exploits—permitting only known good content to enter a facility, network, or system. By comparison, traditional anti-virus and anti-malware generally identify only known bad, which leaves the system vulnerable to exploits that are yet undiscovered. XD Air is also the only U.S. Cyber Command-approved tool for the transfer of classified data using portable media.

Product enhancements include migration to Assured File Transfer (AFT) 1.3 which enables support for Microsoft Office® 2010 file types as well as UTF-8 (Unicode); ability to process file sizes up to 1 GB; support for additional media types including legacy SCADA devices, SD cards, and compact flash media; ability to process USB hard disks up to 250 GB in size as well as floppy disks; and the capability to sign destination media for secure distribution to another site using XD Air. A complete list of enhancements can be found at

“This latest version of XD Air is a milestone in that it is the first wholly-independent release of the product that was originally developed with and for a DoD customer,” said Tresys CEO Gary Latham. “As an increasingly wider audience of customers for XD Air has begun to field the product—particularly in the Critical Infrastructure space—we have been able to further engage with our diverse market to responsively and continually enhance our offering to meet specific use cases and requirements. The result is an assured airgap solution with nearly all new features driven by actual customer usage.”

XD Air version 4.2 is now generally available for shipping. XD Air and required software renewal maintenance can be procured via GSA Schedule GS-35F-0074S, SIN 132-8, Part # XD-A (XD Air product) and SIN 132-12, Part # XD-A_M (XD Air maintenance).
