Compliance and Audit Preparation
CMMC
Compliance Services
Practical support to achieve CMMC certification with clear scoping, evidence-ready documentation, and a structured path to assessment.
CMMC compliance services cover more than technical controls. Meeting the cybersecurity certification requirement means defining your CUI environment, aligning to the right CMMC level, and building the evidence your assessor will actually review.

Strategic Value
Why CMMC Compliance Matters
- You need a clear CMMC level determination and scope definition before starting remediation
- You have gaps in your NIST 800-171 alignment but no prioritized plan to close them
- Your documentation and evidence are disorganized or incomplete heading into assessment
- You want expert CMMC consulting to reduce surprises during your formal self-assessment or C3PAO audit
- You need help connecting your DFARS obligations to your CMMC certification path
Your CMMC Compliance Engagement Includes
You get a structured approach to CMMC readiness that combines scope clarity, control implementation support, and documentation that holds up under C3PAO scrutiny.
CMMC Level Determination and Scope Definition
- Identify CUI locations, data flows, and in-scope systems across your environment
- Define your assessment scope and confirm shared responsibilities with cloud or managed service providers
- Determine the correct CMMC level based on your contract language and CUI handling practices
NIST 800-171 Gap Assessment and Control Implementation
- Review your current security posture against all 110 NIST 800-171 controls and 320 CMMC Level 2 assessment objectives
- Prioritized remediation guidance across access control, incident response, configuration management, and audit logging
- Help establishing control ownership so the right people are accountable for each requirement
SSP, POA&M, and Evidence Readiness
- System Security Plan development and documentation aligned to assessor expectations
- POA&M structure and milestone guidance to support remediation within the 180-day window required to move from Conditional to Final CMMC status
- Evidence planning and artifact organization so you are not rebuilding documentation in the final weeks before your C3PAO assessment
CMMC Assessment Preparation
- Pre-assessment readiness check and refinement of evidence before formal assessment activities begin
- Guidance on common assessor expectations and how to present proof of control performance
- Support for building internal routines so controls stay consistent between triennial assessments

Teams with Incomplete Documentation
Companies that have done some NIST 800-171 work but lack a complete System Security Plan, POA&M, or organized evidence package.
Compliance-Focused Leaders
Leaders who want a clear CMMC compliance roadmap, defined ownership, and a realistic timeline over a generic advisory engagement.

Common Questions
What are CMMC compliance services?
CMMC compliance services help defense contractors achieve and maintain the Cybersecurity Maturity Model Certification required to bid on DoD contracts. Services typically include CMMC level determination, NIST 800-171 gap assessment, System Security Plan development, evidence organization, and pre-assessment preparation.
What is CMMC Level 2 and who needs it?
CMMC Level 2 applies to organizations that handle Controlled Unclassified Information (CUI) in support of DoD programs. It requires alignment to all 110 NIST 800-171 security requirements and involves either a self-assessment or a C3PAO certification depending on program prioritization.
How much does CMMC compliance cost?
CMMC compliance costs vary based on organization size, current security posture, and the number of gaps that require remediation. Nexeris provides a scoped engagement estimate after an initial assessment.
Do you perform CMMC assessments?
Formal CMMC certification assessments are performed by authorized C3PAOs registered through the CyberAB. Nexeris prepares you for that assessment by organizing your program, documentation, and evidence before the assessor arrives.
What is the difference between CMMC and DFARS compliance?
DFARS clause 252.204-7012 requires contractors to implement NIST 800-171, preserve forensic media for 90 days, and report cyber incidents within 72 hours. CMMC adds a validation layer on top of those existing obligations, both frameworks operate concurrently and neither replaces the other.
What is a System Security Plan and why does it matter for CMMC?
A System Security Plan documents your system boundaries, identifies responsible parties, and explains how your organization implements each NIST 800-171 control. It is a primary artifact reviewed during a CMMC Level 2 assessment. Download our free SSP template to see what a complete plan includes.
Can subcontractors be required to meet CMMC?
Subcontractors are required to meet CMMC standards if they handle regulated data flowing down from a prime contractor. Primes bear responsibility for verifying that their supply chain partners maintain current CMMC certificates or self-assessments matched to the data they receive.
How long does it take to get CMMC certified?
Timeline depends on your initial security posture and the volume of gaps requiring remediation prior to formal assessment. Nexeris targets audit readiness in three months or less for organizations that engage fully with our methodology. Review the CMMC 2.0 final rule timeline to understand current enforcement phases.
