TL;DR: Defense contractors still need to treat NIST SP 800-171 as the active baseline, with Drata noting that the 110 requirements remain in force even as CMMC verification timing shifts. The controls and evidence must stay current so CUI contract work does not depend on a later scramble.
Editorial analysis by NHI Mgmt Group, based on content published by Drata: “Post-SOC 2 Playbook for Defense: Building Your CMMC and NIST 800-171 Roadmap”.
Key questions
Q: Why does a CMMC pause not remove compliance risk for contractors handling CUI?
A: Because the pause changes assessment timing, not the underlying obligation to meet NIST SP 800-171.
Q: Where do SOC 2 programmes usually fail in practice?
A: They fail when the team treats compliance as a document exercise instead of an operating discipline.
Q: What should defense contractors do when NIST 800-171 remains the baseline after SOC 2?
A: They should map current SOC 2 evidence to the 110 NIST SP 800-171 requirements and close the gaps tied to CUI handling, rather than waiting for the verification model to stabilise.
Practitioner guidance
- Map SOC 2 evidence to the 110 requirements Create a control-by-control crosswalk from existing SOC 2 evidence to NIST SP 800-171, with explicit notes for gaps such as media protection and CUI-specific reporting.
- Trace DFARS clauses through the supply chain Review the contract or flow-down language before scoping work, and determine whether CUI obligations apply through a prime, subcontract, or downstream vendor relationship.
- Separate control remediation from verification timing Continue closing 800-171 gaps even while CMMC Phase 2 verification remains paused, and treat third-party assessment spend as a contract-triggered decision.
Bottom line: The main risk is treating SOC 2 as the endpoint when defence contracts still require NIST SP 800-171 controls and contract-aware evidence.

Defense compliance after SOC 2 is a control-mapping problem, not a procurement preference. Once DFARS flow-down clauses apply, NIST SP 800-171 becomes the baseline that matters for award eligibility. SOC 2 can provide evidence, but it cannot substitute for the defense-specific control set. Practitioners should treat the compliance model as contractual governance, not optional maturity planning.
A question worth separating out:
Q: What should teams do if DFARS flow-down clauses apply to a subcontractor?
A: They should assume the obligation can inherit through the supply chain and scope the programme accordingly. That means reading the clause early, checking whether CUI can touch the environment, and assigning ownership for the required controls before award timelines force a rushed remediation cycle.
