Defense & National Security

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 authorizing 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 template (aligned to IL5/IL6 control language) scores each suspect ioctl and, when enforcement is armed, terminates the offending process; model-driven persona classification requires the SLM entitlement build, and the default install runs heuristic detection. Every decision is recorded to the continuous, append-only Ledger, which you can export as a governance report an authorizing official can read alongside STIG, FedRAMP High, and CMMC control language. The same air-gap doctrine covers space systems and other national-security programs — an application of the posture, not a separate product.
