Radar, targeting, electronic warfare, and communications hardware suppliers are small specialized firms embedded across every major defense platform. Firmware source code, schematics, and test specifications are CUI, and most electronics companies are storing them in places that don't qualify.
Defense electronics CUI doesn't live in a controlled production area. It lives in laptops, version control repositories, test equipment, and collaboration tools. Firmware source code, FPGA designs, RF characterization data, and system architecture documentation are CUI, and they move through the engineering organization the way any other technical work does. The scoping exercise is about understanding how information flows through the engineering organization, not about identifying where servers sit. Every system that touches defense firmware, schematics, or test data, and every system with network access to those systems, is in scope.
FPGA designs, VHDL, embedded C, DSP algorithms, and boot configurations developed under defense contracts are CUI. Version control repos, build servers, and dev workstations are all in scope.
Native EDA design files and derived outputs, Gerbers, drill files, and BOMs, are CUI. The bill of materials for a defense electronics design reveals component choices that can expose system performance targets.
Antenna patterns, gain measurements, noise figure data, and electromagnetic signature characterization describe what a defense sensor can detect. CUI from the moment it is generated.
Commercial GitHub, GitLab, and Azure DevOps SaaS are not FedRAMP Moderate authorized. Defense firmware in those repositories is non-compliant and one of the most common findings in electronics assessments.
The most common finding in defense electronics assessments isn't in the hardware. It's in the source control platform. If your defense firmware is in a commercial cloud repository, that finding exists today. Talk to us about what it takes to remediate it.
Defense electronics companies cannot use cloud-hosted compliance platforms any more than they can store firmware in commercial cloud repos. The same principle applies: sensitive design data must not leave the facility to reach a compliance tool. 1TEN deploys on-premises as a dedicated appliance inside your engineering network. Firmware, schematics, and test data never leave your environment. The compliance program runs alongside the engineering work it governs, not on a platform outside your boundary.
Guidance on compliant repository hosting for defense firmware: on-premises options and FedRAMP-authorized alternatives to commercial cloud platforms.
System boundary documentation for complex engineering environments: build servers, test equipment, simulation environments, and documentation platforms all addressed.
Role-based access documentation for firmware repositories and design systems, with the version history audit logging that assessors specifically examine in electronics environments.
Installed inside your engineering network. No external connectivity. Firmware, schematics, and test data stay where they belong, inside your controlled environment.
1TEN is the GRC platform built specifically for small defense manufacturers navigating CMMC Level 2.
