GMS Introduces Three Open-Standard Cross Domain Systems for Secure Battlefield Data

General Micro Systems (GMS) has unveiled the latest additions to its XDomain family of open-standard cross domain systems (CDSs) at AUSA 2025.

The new systems are designed to perform a dual function: securing data at rest and in motion by separating Red (classified) and Black (unclassified) domains while also providing high-performance mission, sensor, and payload processing.

With the Combined Joint All Domain Command and Control (CJADC2) approach and the proliferation of smart sensors and legacy platforms, data is increasingly required to cross secure boundaries. Cross domain systems ensure the secure, rules-based transfer of data, but traditional solutions have been large, proprietary, and expensive. GMS aims to address this with its new, standards-based systems that use MOSA-standard Ethernet and Thunderbolt 4.

Ben Sharfi, CEO and Chief Architect, GMS, commented, “We’ve torn that model to shreds. We’ve created three open standard-based small, lightweight, and low-cost cross domain systems that fit into swarm UAVs, mobile and portable deployments, vehicles, and more. There’s nothing in the market even close—and you’re not going to find it because it’s our X9 architecture that’s made it possible and no one else has X9. However, each CDS in the XDomain family is MOSA-inspired and based upon the industry’s only open standards: Thunderbolt 4 and Ethernet. Why has nobody done this before?”

The new XDomain products include the X9 SPIDER “TacKit” Mini-Stack, the X7 RAPTOR Nano-Stack, and the VENOM ‘VIPER’ NanoATR, a SOSA-aligned OpenVPX chassis, all based on the GMS Technology Readiness Level (TRL) X9 architecture. Each system includes a Red domain, a Black domain, and a General Dynamics KG-175N Type 1 HAIPE encryptor. The domains are fully isolated and function as high-performance mission processors with high-speed networking, Thunderbolt 4, and various I/O options.

The X7 RAPTOR Nano-Stack is the smallest and lightest of the three, weighing under five pounds with a footprint of 4” x 4” x 6”. It uses two X7 RAPTOR mission computers to provide dual-CPU performance based on Intel Core i7 8-core processors and up to 128 GB of DDR4 memory. Designed for use in high-volume applications like swarm drones or portable networks, it uses a General Dynamics TACLANE encryptor to separate the domains.

The X9 SPIDER “TacKit” Mini-Stack is slightly larger at 5” x 6” x 6.5” and under nine pounds. It utilizes dual X9 SPIDER mission computers and includes four Thunderbolt 4 ports per computer. It can also be scaled with I/O such as MIL-STD-1553, quad 100 GbE fiber network ports, dual SSDs, and an NVIDIA A4500 GPGAPU for AI processing.

The VENOM “VIPER” NanoATR is a standard-size ½ ATR (short) conduction-cooled chassis with GMS-unique per-slot cooling. The 4-slot 3U chassis can dissipate up to 800 W. It uses dual VENOM single-board computers (SBC) to serve as mission processors on independent backplanes.

Sharfi added, “No vendor or prime DoD contractor has systems that fit into such small spaces, weigh so little and are yet so full-featured, powerful, completely off-the-shelf and ready to deploy. They’re the culmination of 46 years of experience building secure, rugged, networked, sensor processing and storage systems and learning from security partners such as General Dynamics Mission Systems and even the Army, Navy and Air Force. They will truly change secure, interoperable communications for years to come.”
