What C3PAOs Really Look for Under CMMC Rule 48
Lessons from Our Latest Webinar
Yesterday’s live webinar, Straight Talk with a C3PAO: Preparing for Assessments Under Rule 48, hosted by Cyber Defense Advisors (CDA) in partnership with Insight Assurance, brought together dozens of defense contractors and compliance professionals for one reason: To finally get straight answers on what CMMC Rule 48 really means in practice.
From Uncertainty to Clarity
CMMC Rule 48 is officially here, and for many contractors, the question isn’t whether they care about compliance. It’s whether they truly understand what readiness looks like when a C3PAO shows up. The webinar tackled that question head-on, replacing guesswork with actionable steps grounded in real assessment experience.
Adam Glover, Director of Audit Services at Insight Assurance and a certified C3PAO assessor, gave attendees a rare inside look at how assessments are actually conducted under Rule 48. He emphasized that “readiness” is measured not by paperwork but by consistent operational behavior—proof that policies are followed, roles are understood, and evidence exists to back it all up.
CDA’s Bryan Siegel, Director of Cyber Compliance, guided the discussion, connecting these insights to the 30-Day Readiness Sprint, a practical framework CDA uses to help GovCon firms prepare for CMMC Level 2. That sprint outlines, week by week, how to go from scattered documentation to a clean, defensible system that instills confidence in any assessor.
Real Guidance for Real Assessments
Participants walked away with concrete steps to implement immediately, including how to:
- Define and defend your boundary with one simple diagram showing where CUI lives and who owns it.
- Turn policy into practice by showing activity logs, timestamps, and evidence that people actually perform required actions.
- Build an Evidence Map linking every control to a dated artifact and one backup.
- Rehearse the assessment so every control can be answered in two minutes or less.
Glover also shared five key signals assessors look for: scope clarity, clean evidence, least privilege in action, working detection systems, and leadership engagement.
The Real Message: Discipline Over Documentation
The discussion reinforced a simple truth: Rule 48 isn’t about surviving a checklist. It’s about proving operational discipline. Fancy tools and policy templates can’t substitute for an organization that consistently follows its own procedures. The best assessments, Glover noted, “are the boring ones—because everyone already knows what they’re doing.”
