Key Takeaways (TL;DR)

  • Before the official C3PAO assessment, contractors must go through a thorough readiness phase that includes gap analysis, remediation planning, documentation, and staff training—laying the groundwork for a smooth, successful certification.
  • Rushing or skipping the readiness phase can result in failed audits, costly delays, and lost contract opportunities. Taking the time to prepare helps eliminate surprises and ensures your organization is truly assessment‑ready.
  • Total Assure offers tailored readiness support so DoD contractors can approach CMMC with confidence and avoid unnecessary stress.

What Is the Readiness Phase?

The readiness phase is the comprehensive preparation process that ensures your cybersecurity practices meet the specific requirements of your CMMC level before the formal assessment. Unlike the official assessment—performed by an independent C3PAO—the readiness phase is an internal or assisted effort focused on identifying gaps, remediating risks, documenting controls, and training staff. Think of it as the groundwork that makes the assessment smoother, faster, and less stressful.

The Core Components of the Readiness Phase

1. Comprehensive Gap Assessment

Evaluate your current cybersecurity posture against the CMMC controls required for your certification level:

  • Review existing policies, procedures, and technical controls
  • Interview key personnel to understand current practices
  • Evaluate risk‑management practices such as vulnerability scanning

Outcome: A detailed gap report highlighting shortfalls and recommended improvements.

2. Prioritized Remediation Planning

After identifying gaps, create a clear, actionable plan to close them:

  • Prioritize tasks based on risk
  • Assign responsibilities to team members or contractors
  • Validate that security controls are implemented effectively

3. Developing and Updating Policies and Procedures

Documentation is a cornerstone of CMMC compliance:

  • Create or update cybersecurity policies (access control, incident response, data management, etc.)
  • Ensure policies reflect actual practices and are accessible to employees
  • Integrate policies into daily workflows and gather evidence that they are followed

4. Technical Controls Implementation

Strengthen technical defenses and gather evidence of control effectiveness:

  • Deploy or enhance firewalls, IDS/IPS, encryption, and MFA
  • Configure systems to meet access and monitoring requirements
  • Regularly test controls and maintain logs demonstrating they are operational

5. Employee Training and Awareness

Your cybersecurity posture relies heavily on informed employees:

  • Conduct role‑based training sessions
  • Emphasize compliance responsibilities and reporting procedures
  • Foster a culture of security awareness to reduce phishing and social‑engineering risks

6. Internal Review and Mock Assessments

Conduct internal reviews or mock assessments to surface overlooked issues:

  • Simulate the assessment to practice interviews and documentation reviews
  • Use findings to refine remediation efforts
  • Build confidence across the organization before engaging the C3PAO

Why the Readiness Phase Matters

Skipping or rushing readiness can lead to:

  • Failed audits and re‑work costs
  • Delayed contract awards or lost opportunities
  • Surprise findings during the formal assessment
  • Higher overall costs versus proactive remediation
  • Lower team morale and confidence

Completing a structured readiness phase prevents surprises, saves money, and streamlines certification.
