Submit any questions you would like answered on the podcast!Are assessors judging you on CMMC or NIST 800 171 when audit day arrives?In this episode of the CMMC Compliance Guide Podcast, Stacey and Brooke break down the real relationship between CMMC 2.0 and NIST 800 171 so you are not guessing when it matters most.We walk through how the 110 NIST 800 171 controls and 320 assessment objectives drive your CMMC level 2 certification, and what CMMC layers on top, including POA&M limits, timelines, and who is allowed to certify you. You will hear practical examples around SPAs, cloud tools, customer responsibility matrices, FedRAMP, and how assessors actually validate things like MFA, logging, and scope.We also explain the difference between a NIST self assessment and a CMMC level 2 certification by a C3PAO, clear up common misconceptions about “being NIST compliant”, and talk about False Claims Act risk when SSPs, inventories, and controls are not kept current. Finally, Brooke shares a step by step path for contractors: identify your CUI, scope systems, run a gap analysis, build your SSP and POA&M, collect evidence, and engage a C3PAO for a mock and full assessment.If you are a small or midsized defense contractor trying to get ready for 2026, this episode will help you focus on what assessors really care about so you can prepare with confidence.
