The DoD’s CMMC FAQ has been updated again. If you are working toward Level 2 certification, FAQ updates are not background noise. They are the closest thing to interpretive guidance you get between rulemakings, and assessors read them.
The latest version, CMMC FAQ Revision 2.3 from May 2026, is worth reviewing closely. For small-to-medium DIB contractors, 32 CFR Part 170 sets the rules, but the FAQ is where DoD clarifies how those rules get applied in practical situations.
When DoD updates FAQ language, scoping decisions, asset categorization calls, and SSP language can all be affected. Pretending the previous version is still current is one of the easier ways to walk into an assessment with stale assumptions.
Why FAQ Updates Matter
Each FAQ refresh tends to do one of three things:
- Clarify a previously ambiguous requirement, which can narrow or expand what counts as in scope.
- Reinforce an existing interpretation that the field has been overlooking.
- Address a question that has come up often enough in assessments to warrant a written answer.
None of these are theoretical. If you have a draft SSP, a gap assessment, or a POA&M built against a prior FAQ, parts of it may now be out of step with current DoD interpretation.
That does not necessarily mean rework. It does mean review.
What to Do This Week
If your company touches the DIB supply chain, or supports clients who do, here are a few actions worth taking this week:
- Read the updated FAQ in full. Do not rely only on summaries from forums, vendor blogs, or social posts, including this one. The FAQ is short enough to read end to end, and the wording matters.
- Compare it against your current scoping decisions. If any FAQ answer touches how you categorized CUI Assets, Security Protection Assets, Contractor Risk Managed Assets, Specialized Assets, or Out-of-Scope Assets, flag those decisions for review.
- Check your SSP language. If your SSP cites or paraphrases FAQ guidance that has been revised, update the language before an assessor catches the mismatch.
- Cross-check against NIST SP 800-171 Rev. 2 mappings. FAQ clarifications do not change the underlying 110 practices or 320 assessment objectives, but they can affect how a specific objective gets evaluated in context.
What Not to Do
Do not assume a FAQ update is a green light to broaden scope reductions or claim new exemptions. FAQ updates usually clarify interpretation. They should not be treated as new exceptions unless the source language clearly says so.
If a community post or vendor blog is reading the new FAQ as a relief mechanism, treat that as analysis, not fact, until you have confirmed it against the source language.
Also, the FAQ is not a substitute for the CMMC Level 2 Scoping Guide or the CMMC Assessment Guide. It clarifies. It does not supersede.
Where This Leaves You
FAQ updates are easy to miss, but they can affect how a contractor explains scope, asset treatment, system changes, and SSP language. The risk is not usually that you missed the rule. It is that your assessment package still reflects an older interpretation.
If you are preparing for CMMC Level 2, now is the time to compare the May 2026 FAQ against your current scope, asset inventory, network diagrams, and SSP. If something has changed, clarify it before Phase 1 of your C3PAO assessment begins.
A Note on Phase Language
A recurring point of confusion among DIB companies I speak with is the word “phase.” In CMMC, it can refer to the DoD’s phased rollout of contract requirements, or to the phases of a C3PAO assessment. Those are different timelines. Before acting on official guidance, make sure you know which one is being referenced.
