Air-gapped AI governance for classified and CUI workloads — with a kernel-grade audit ledger your accrediting official can read.
FedRAMP HIGHDoD IL5 · IL6STIGCMMCCUI
Imagine a defense prime or national-security program office running mission models on accredited GPU enclaves. The mandate is absolute: no outbound network, CUI and classified data never cross the boundary, and every AI decision must be evidenced for the accrediting official. Arca Sentry deploys fully air-gapped — license verified offline, zero phone-home — and attaches at the NVIDIA driver boundary on every host. The DoD Sentinel persona (IL5/IL6) scores each suspect ioctl and blocks model-weight or CUI exfiltration before bytes leave the GPU. Every verdict seals into the kernel-grade Ledger, which becomes accreditation evidence an authorizing official can map directly to STIG, FedRAMP High, and CMMC controls. The same air-gap doctrine covers space systems and other national-security programs — an application of the posture, not a separate product.
// AT FLEET SCALE · ARCA NEXUS
One Nexus per enclave rolls every Sentry's verdicts into a single signed chain of evidence — the accreditation artifact an authorizing official wants for the whole air-gapped program, not a stack of per-host logs.
