CMMC Readiness Assessment

CMMC Readiness Assessment

CMMC isn’t a box-checking exercise. If you handle CUI, you need to know where you actually stand, find the gaps, and build a realistic path to assessment readiness. The Mythos CMMC Readiness Assessment evaluates your cybersecurity maturity, measures your NIST SP 800-171 implementation, pinpoints what needs work, and prepares you for a formal CMMC assessment — with security improvements that reduce risk and support compliance for the long haul.

Why it matters

Plenty of organizations believe they’re compliant until a formal assessment exposes documentation gaps, control deficiencies, incomplete processes, or missing evidence. A readiness assessment surfaces those issues before they become findings — so you understand your maturity, identify NIST 800-171 gaps, evaluate your CUI protection, improve documentation, prioritize remediation, reduce assessment risk, and give leadership what they need to plan and budget.

What’s included

  • CMMC readiness review
  • NIST SP 800-171 gap assessment
  • CUI boundary evaluation
  • System Security Plan (SSP) review
  • POA&M review and recommendations
  • Microsoft 365 security assessment
  • Identity and access management review
  • Multifactor authentication validation
  • Logging and monitoring evaluation
  • Policy and procedure review
  • Evidence readiness review
  • Risk prioritization workshop

How the assessment works

1. Discovery and scoping

We start by understanding your business, contract requirements, technology environment, and compliance goals — including CUI identification, system boundary review, and stakeholder interviews.

2. Documentation review

We review your SSP, policies, procedures, risk management documentation, training records, and incident response documentation to find gaps and inconsistencies.

3. Technical evaluation

We evaluate your technical safeguards and operational controls: Microsoft 365, identity security, access control, logging, vulnerability management, and endpoint security.

4. Gap analysis

We map findings against the applicable requirements and prioritize by risk and readiness impact — control gaps, documentation gaps, evidence gaps, process deficiencies, and governance observations.

5. Executive briefing

Leadership gets a clear overview of findings, risk exposure, and priorities, plus budgetary and strategic considerations.

6. Remediation roadmap

You leave with a structured plan to improve readiness and support ongoing compliance.

Frequently asked questions

Is this a formal CMMC assessment?

No. It’s a readiness assessment that identifies gaps and improves your preparedness before formal assessment activities. Certification is issued by an authorized C3PAO.

How long does it take?

It depends on your size and complexity, but most engagements wrap within a few weeks.

Do we need a finished SSP first?

No. Organizations at any stage of maturity benefit from the process.

Can you help with remediation afterward?

Yes — remediation planning, documentation, Microsoft 365 security improvements, governance development, and ongoing compliance support.
