8 Recommendations for Businesses Approaching CMMC in 2025

The CMMC framework represents a critical shift in how the Department of Defense safeguards its digital supply chain. Starting in 2025, all DIB contractors must meet the new certification requirements to compete for or maintain DoD contracts. Preparing for CMMC certification can be complex, but businesses can navigate these challenges effectively with the right approach. Below is a detailed guide for companies aiming to achieve CMMC compliance.

 

CMMC 2025 suggestions

1. Understand Appeals Processes for C3PAO Decisions

For businesses pursuing CMMC certification at Levels 2 and 3, assessments will be conducted by Certified Third-Party Assessment Organizations (C3PAOs). While the certification process is structured and thorough, disagreements with assessment results may occur. Here’s what you need to know:

  • Prepare Strong Documentation: Comprehensive documentation of your cybersecurity controls and processes is essential. This includes System Security Plans (SSPs), Plan of Action and Milestones (POA&Ms), and evidence of control implementation. Clear documentation reduces the likelihood of disputes.
  • Understand the Appeals Process: If you believe a C3PAO has made an error, you can appeal through the CMMC Accreditation Body (CMMC-AB). Ensure that you keep all your assessment documentation and your internal knowledge of your IT systems. Ensure your appeal is supported by detailed evidence, such as audit logs, reports, or correspondence demonstrating compliance.
  • Engage Experts Early: Pre-assessment consultations with cybersecurity experts can help you get on the right track before you begin assessment or documentation.

Being proactive and well-prepared is key to minimizing issues and resolving them efficiently if they arise.

 

2. A Small Business? Understand Your Unique Challenges

Small businesses often lack the resources of larger enterprises, making CMMC compliance particularly challenging. However, with targeted strategies, these businesses can overcome the barriers:

  • Financial Challenges: CMMC compliance often requires significant investment in cybersecurity tools, infrastructure, and expertise. Small businesses should explore government programs offering financial assistance, such as DoD grants or subsidies for cybersecurity improvements.
  • Limited Technical Expertise: Many small businesses lack dedicated IT teams. Partnering with MSSPs can help fill this gap. These partners offer expertise in cybersecurity and CMMC requirements and provide cost-effective solutions tailored to small organizations.
  • Time Constraints: Compliance efforts can detract from core business operations. Establishing a phased implementation plan with clear milestones allows small businesses to allocate resources efficiently while minimizing disruptions.

Small businesses should view CMMC compliance as an investment in long-term resilience and competitiveness in the defense sector.

 

3. Cultivate an Understanding of NIST Special Publication 800-171

The CMMC Level 2 requirements align with the 110 controls of NIST Special Publication 800-171, which focuses on protecting CUI. Businesses following NIST 800-171 will have a significant head start on achieving CMMC certification. By integrating CMMC with NIST 800-171 practices, businesses can reduce redundancy and streamline compliance efforts.

  • Crosswalk Your Controls: Perform a mapping exercise to identify how your existing NIST 800-171 controls align with CMMC requirements. Use guides and resources provided by NIST and the CMMC-AB.
  • Leverage Existing Policies: If your business has documented procedures and technical controls for NIST 800-171, adapt these for your CMMC submission. For instance, practices like access management, audit logging, and incident response are standard in both frameworks.
  • Close Gaps Efficiently: Use gap analysis to identify discrepancies and prioritize remediation based on risk and cost-effectiveness.

 

4. Focus on Your System Security Plan 

An SSP is the cornerstone of any CMMC compliance effort. It documents how your organization implements cybersecurity practices and protects sensitive information.

  • Develop a Comprehensive SSP: Include detailed descriptions of security controls, the scope of systems covered, and responsible personnel. Ensure that the SSP is easy to understand and updated regularly.
  • Create a POA&M: Create a POA&M for any gaps identified during internal audits or pre-assessments. This document should outline steps to remediate deficiencies, assign accountability, and provide realistic timelines for completion.
  • Maintain as a Living Document: Update your SSP and POA&M whenever your systems or processes change. Treat these documents as active tools for maintaining compliance rather than static reports. An up-to-date SSP and POA&M ensure compliance and demonstrate organizational commitment to cybersecurity.

 

5. Engage Third-Party Expertise

Navigating the complexities of CMMC can be overwhelming, especially for businesses unfamiliar with its requirements. Partnering with cybersecurity experts can simplify the process.

  • Pre-Assessments: Conduct mock assessments with Registered Practitioners. These experts can identify weaknesses and recommend targeted improvements outside a C3PAO relationship. Note that your RP cannot serve as your C3PAO. You can find authorized RPs and C3PAOs on the CyberAB Marketplace. 
  • Consultation: Expert consultants can guide your organization in implementing technical controls, preparing documentation, and training employees. Engaging experts ensures compliance efforts are efficient, effective, and aligned with CMMC standards.
  • Managed Security Service Providers: MSSPs can provide ongoing support, monitoring, and maintenance of cybersecurity controls.

 

6. Know When and Where Assessments Occur

Understanding these timelines and assessment protocols ensures your organization is prepared well. Assessment timing and methodology depend on your organization’s desired CMMC certification level:

  • Level 1: Requires self-assessment annually, with results submitted to the DoD.
  • Level 2: This level requires triannual assessments by a C3PAO (while self-assessments are possible, third-party assessments are far more common). These assessments focus on the organization’s adherence to NIST 800-171 and additional CMMC-specific practices.
  • Level 3: Requires government-led audits for contractors handling sensitive information.

 

7. Automate Compliance Processes

Automation is a game-changer for organizations managing multiple cybersecurity frameworks. Investing in automation tools can significantly reduce the complexity of compliance and enhance operational efficiency.

Automated tools can streamline the process by:

  • Mapping Controls Across Frameworks: Automatically identify overlaps between CMMC and other standards like NIST 800-171, ISO 27001, or SOC 2.
  • Real-Time Monitoring: Use automated solutions to monitor your security posture and alert you to potential compliance issues.
  • Streamlining Reporting: Generate audit-ready reports quickly, saving time during assessments.

 

8. Understand Affirmation Requirements

Affirmations are a critical component of CMMC certification, requiring senior leadership to attest to the implementation and maintenance of cybersecurity controls.

  • Leadership Accountability: Designate a member of senior management responsible for reviewing and affirming compliance.
  • Periodic Reviews: Schedule regular internal audits to confirm the effectiveness of implemented controls and ensure they align with your affirmations.
  • Detailed Documentation: Maintain thorough records of compliance activities to support affirmations during assessments.
