New $2,499 PXIe-GPU-T400 Enables Popular NI & Keysight PXIe Embedded Controllers to Maintain Strict Windows 11 Security While Providing Enhanced GPU Performance
SAN JOSE, Calif., May 12, 2026 /PRNewswire-PRWeb/ -- RADX Technologies, Inc. ("RADX"), a leader in COTS, high-performance, computing technologies and products for modular Test & Measurement (T&M), today announced the Catalyst PXIe-GPU-T400-2GB-1SP. Priced at $2,499, the PXIe-GPU-T400 provides a cost-effective solution for addressing important Windows 11 security incompatibilities and vulnerabilities affecting PXIe Systems with Embedded Controllers (ECs) equipped with End-of-Life (EOL) AMD and Intel Integrated Graphics Processing Units (IGPUs) that feature Windows Driver Software that is no longer supported and is End-of-Service (EOS).
BACKGROUND - With its high performance, software-defined architecture, broad industry support and long-life-cycle support, PXIe Systems are now the most popular modular T&M platform in the world. As PXIe Systems transition to Windows 11, the EOL/EOS IGPUs in popular PXIe Embedded Controllers preclude the operation of Memory Integrity (Hypervisor-Protected Code Integrity - HVCI) and Core Isolation features that implement Virtualization-Based Security (VBS) to prevent malware from accessing high-security processes. Windows 11 Memory Integrity / Core Isolation is directly applicable to NIST SP 800-171 Requirements and CMMC 2.0 Practices CM-6, SI.L2-3.14.1, SC.L2-3.13.11 and AC.L2-3.1.2. To use these EOL/EOS IGPUs, PXIe System users must either disable Windows 11 Memory Integrity, risking potential cybersecurity attacks and NIST SP 800-171 / CMMC 2.0 Compliance, or they must disable the EOL/EOS IGPUs and downgrade to low-resolution, Standard Microsoft Display Drivers, which are unsuitable for T&M applications that require multiple monitors, complex GUIs, high-res graphics, video or compute acceleration. Known security vulnerabilities associated with EOL/EOS IGPUs in NI PXIe-8881, Keysight M9038A and Keysight M9035A Embedded Controllers are shown below and in the attached table:
NI PXIe-8881 PXIe Embedded Controller
- Integrated GPU / Driver: AMD Radeon E6465 and Driver atdcm64a.sys
- Vulnerability / Issue Description: Microsoft Driver Blocklist Flag - The native AMD driver contains unpatched privilege escalation risks. To use the display without crashing, users must disable Memory Integrity or the Vulnerable Driver Blocklist.
- Severity: High
Keysight M9038A PXIe Embedded Controller
- Integrated GPU / Driver: Intel UHD Graphics 630 and Driver igdkmd64.sys
- Vulnerability / Issue Description: Improper Access Control - Legacy generations of Intel IGPU drivers contain local access flaws. Allows an authenticated local attacker to cause denial of service (DoS) or execute unauthorized code.
- Severity: Medium
Keysight M9035A PXIe Embedded Controller
- Integrated GPU/ Driver: Intel HD Graphics 530 / 630 with Driver: igdkmd64.sys
- Vulnerability / Issue Description: Susceptible to common local privilege escalation vectors found in older Intel DCH driver packages. Requires strictly controlled driver updates to patch, which IT departments frequently delay to prevent breakages.
- Severity: Medium
PXIe-GPU SOLUTION – Disabling EOL/EOS IGPUs in Embedded Controllers and adding a RADX Catalyst PXIe-GPU to PXIe Systems enables full compliance with Windows 11 Security. In addition, users may realize multi-monitor display, 2D/3D graphics, video and compute benefits that are intrinsic to modern NVIDIA GPUs. Catalyst PXIe-GPUs are COTS NVIDIA Professional PCIe GPUs packaged for PXIe via RADX' patented Catalyst-X™ technology (U.S. Patent 12,284,547). Accordingly, Catalyst PXIe-GPUs use NVIDIA standard, fully compliant, WHQL-signed, enterprise drivers that natively support Windows 11 Virtualization-Based Security (VBS) and Windows 11 Memory Integrity, Vulnerable Driver Blocklist, and Kernel DMA Protections, without affecting their PXIe system's operation.
"Windows 11 VBS is an important defense against kernel-level malware. Disabling this protection to use obsolete components and drivers may be understandable in the short term, but it's likely not a viable long-term security approach for sensitive systems or CMMC 2.0 compliance, said Leighton Johnson, CMMC LCCA, CISA, CISSP and Director of Cybersecurity at Acquired Data Solutions. "Where possible, organizations should remove unsupported drivers to eliminate known vulnerabilities by employing current hardware and authenticated drivers."
ABOUT THE PXIe-GPU-T400 - Based on the NVIDIA T400 and priced at $2,499 (with free shipping in the USA), the PXIe-GPU-T400 is the lowest-priced member of the Catalyst Family of COTS PXIe-GPUs (www.radxtech.com/pxie-gpus). With its aggressive price, the T400 provides a cost-effective solution for addressing Windows 11 Security Issues associated with EOL/EOS IGPUs in PXIe Embedded Controllers. The T400 enables users to maintain good cybersecurity hygiene and pass strict cybersecurity audits, while preserving their investments in PXIe-based instrumentation. The T400 has a ~30-day ARO lead-time and is available directly from RADX ([email protected]), qualified VARs and System Integrators and via TestMart ([email protected]) for US Government related Purchases.
The PXIe-GPU-T400 supports up to three (3) high-res monitors and provides superior 2D/3D graphics and video when compared to IGPUs. In addition, the T400 supports entry level NVIDIA CUDA and OpenCL-based GPU-accelerated computer vision, signal processing and AI via LabVIEW, G2CPU, Python, PyTorch, MATLAB, LibTorch, C/C++, TensorFlow and similar computing frameworks.
