What is CMMC Compliance, and Why Should You Care?
Organizations working with the U.S. Department of Defense (DoD) must understand CMMC compliance. The Cybersecurity Maturity Model Certification (CMMC) is a crucial initiative designed to safeguard sensitive information within the Defense Industrial Base (DIB).
This guide explores what CMMC entails and why achieving CMMC compliance is essential for manufacturers in the aerospace and defense industries.

Understanding CMMC Compliance Requirements
The DoD developed the CMMC framework to assess the cybersecurity maturity of its contractors and subcontractors. CMMC compliance ensures that organizations possess the necessary cybersecurity controls to protect sensitive information, known as Controlled Unclassified Information (CUI).
The DIB encompasses a vast network of businesses contributing to national security — from major aerospace firms to smaller IT solution providers. CUI includes design specifications, technical data, and financial information that is not classified but still considered sensitive.
The Federal Register published the CMMC Final Rule on October 15, 2024, with requirements becoming enforceable November 10, 2025. CMMC introduces a standardized approach, providing a more reliable assessment of defense contractor preparedness.
CMMC's Three-Tier Certification Model
CMMC utilizes a tiered certification model based on information sensitivity and security requirements:
CMMC Level | Security Focus | Assessment Type | Key Requirements |
Level 1: Foundational | Basic cybersecurity practices | Annual self-assessment | • Access controls • Password management • System monitoring • FAR clause 52.204-21 compliance |
Level 2: Advanced | Comprehensive security program | C3PAO certification every 3 years (most contractors) | • NIST SP 800-171 (110 controls) • Incident response • Risk management • Security awareness training |
Level 3: Expert | Proactive threat management | DIBCAC government assessment | • All Level 2 requirements • Penetration testing • System hardening |
The specific CMMC level required depends on the type of work performed and the sensitivity of data handled. A company providing basic office supplies might only need Level 1, while a contractor developing classified weapon systems could require Level 3.
At Modus Advanced, we're actively working toward CMMC compliance (practices from Levels 2 and 3) to ensure the data we handle for your life-saving and life-changing devices are safe from bad actors.
CMMC Compliance Implementation: 7 Critical Steps
Organizations working with the DoD must achieve the CMMC level specified within their contract. Here's your roadmap to CMMC compliance:
1. Select the Appropriate CMMC Level
Understand your contracts and the type of data you handle. DoD contracts explicitly state the necessary CMMC level for the work.
2. Identify Affected Assets
Document your IT infrastructure, systems, and data storing CUI — including hardware, software, and cloud-based solutions.
3. Choose a Technical Design
Develop a security architecture that aligns with your CMMC level. Select appropriate security tools and technologies based on your specific requirements.
4. Implement Security Measures
Put in place controls based on your CMMC level:
- Firewalls: Network perimeter protection
- Intrusion Detection Systems (IDS): Real-time threat monitoring
- Data Encryption: Protection of data at rest and in transit
- Malware Protection: Anti-virus and anti-malware solutions
5. Partner with a Managed Service Provider (MSP)
An MSP experienced in CMMC compliance can provide guidance on implementing controls, conducting gap assessments, and preparing for CMMC assessment.
6. Prepare Required Documentation
Compile comprehensive documentation demonstrating adherence to CMMC requirements:
- Security policies: Written procedures and standards
- Training records: Evidence of security awareness programs
- System configuration details: Technical specifications and settings
- Assessment procedures: Testing and validation records
7. Complete the CMMC Assessment
An authorized C3PAO will evaluate your security practices through documentation review, interviews, and observation of security controls in action.
Why CMMC Compliance Matters for Defense Contractors
CMMC compliance delivers critical benefits beyond contractual requirements:
Protection of Sensitive Military Intelligence
Robust cybersecurity safeguards minimize breach risks involving classified information. CMMC ensures contractors prioritize cybersecurity, safeguarding information vital to national defense and preventing disruptions to critical DoD operations.
Enforcement of Consistent Cybersecurity Standards
CMMC establishes a baseline for cybersecurity across the DIB, eliminating the vulnerabilities that existed when practices varied greatly. This creates a more secure environment for information sharing and makes it harder for malicious actors to gain a foothold.
Accountability and Collaboration
CMMC fosters shared responsibility for cybersecurity, promoting collaboration between DoD contractors and the government. This approach strengthens the overall security ecosystem through open communication about risks and mitigation strategies.
Maintenance of Public Trust
CMMC certification demonstrates your commitment to cybersecurity best practices and assures the public that their tax dollars are invested in organizations that take data security seriously.
Consequences of Failing to Achieve CMMC Compliance
Non-compliance with CMMC compliance requirements creates severe risks:
Consequence | Impact |
Contract Ineligibility | Cannot bid on, win, or maintain DoD contracts. Contracting officers will not make award, exercise options, or extend performance periods without passing assessment results. |
National Security Risks | Inadequate cybersecurity leaves CUI vulnerable to cyberattacks, potentially compromising sensitive data and disrupting critical DoD operations. |
Reputational Damage | News of cyberattacks or non-compliance severely damages reputation, making it difficult to attract partners and eroding public trust. |
Financial Impact | Exclusion from the $313 billion DoD acquisition marketplace significantly impacts revenue for businesses relying on government contracts. |
Building a Secure Future Through CMMC Compliance
CMMC compliance isn't just a formality — it's a critical step for organizations working with the DoD. By achieving the necessary CMMC level, businesses contribute to a more secure Defense Industrial Base, ensuring the protection of sensitive information and maintaining public trust.
Taking proactive steps towards CMMC compliance demonstrates your commitment to cybersecurity best practices and strengthens your position as a reliable partner for the DoD. With the November 10, 2025 enforcement date now in effect, organizations must act immediately to ensure they meet requirements.
