NIST 800-171

The RFI summary Federal News Network obtained puts the cost of CMMC in NIST SP 800-171 implementation and evidence assembly, and the task force's remedies are clearer CUI marking and machine-readable assessment evidence in OSCAL. Microsoft's one published availability table marks every Purview agent capability unavailable in GCC, and it publishes no per-capability table at all for GCC High or DoD.

The first surveys since the CMMC Phase 2 pause show the compliance drift mostly did not happen. About 78% of contractors kept going; a roughly 22% minority slowed, and the pullback was in certification spend, not controls.

CUI protection was built for data at rest and data in transit. A prompt to a frontier model is neither, and each hop it takes, from prompt to cache to training, carries a different DFARS obligation. GSA's first AI-specific safeguarding clause takes effect October 19, 2026.

A contractor can inherit 80 to 90 percent of its CMMC controls from an MSP or cloud platform. The shortcut solves the cost and assessor bottleneck, and it concentrates the residual risk in a customer responsibility matrix most small firms can't read.

Deep Fathom's April 2026 Compliance Readiness Suite is the first agentic product aimed at the contractor side of CMMC. What is actually in it, and what the vendor's claims leave unproven.

Don't mistake a procedural pause in CMMC Phase 2 for a regulatory retreat. The compliance shadow is growing.

As AI agents enter the Defense Industrial Base, they create a massive compliance blind spot. Traditional security models like sandboxing won't satisfy CMMC 2.0's data-layer requirements.

The FY2026 NDAA ordered the Pentagon to build an AI/ML security framework and fold it into DFARS and CMMC. The human-era rule is paused mid-rollout, so defense contractors sit between a rule that cannot see their agents and a successor rule that is signed but not in force.
