Submit any questions you would like answered on the podcast!Today’s episode of the CMMC Compliance Guide Podcast dives into the biggest myths that machine shops, fabricators, CNC shops, and mid-sized defense contractors still believe about CMMC. From cloud misconceptions to vendor promises that fall short, Brooke breaks down why these misunderstandings lead to failed assessments and what contractors should be doing instead.We walk through common assumptions like “cloud keeps me out of scope,” “my vendor is compliant so I’m compliant,” “MFA on email is enough,” “my firewall makes everything compliant,” and “cyber insurance handles reporting.” Each of these has a grain of truth but none of them meet the actual requirements in NIST 800-171 or CMMC Level 2.You’ll learn:Why cloud environments don’t remove your endpoints from scopeHow caching, downloads, and browser access pull systems back into scopeWhat vendor claims really don’t coverWhy MFA must be implemented everywhere CUI is accessed, not just emailThe truth about firewalls and why they’re not “compliance shields”Why VDI is helpful but not a magic solutionWhat cyber insurance does (and doesn’t) do during an incidentWhy remote workstations and home offices still introduce scope and riskThis episode is packed with clarity, not fear so manufacturers, CNC shops, and GovCon SMBs can make informed decisions, avoid costly assumptions, and protect their DoD contracts.
