Why CMMC Level 3 is critical for your DoD contracts and how Scrut makes it manageable

With rising cyber threats targeting the Defense Industrial Base (DIB), the Department of Defense (DoD) is enforcing stricter standards through the Cybersecurity Maturity Model Certification (CMMC). For contractors, this isn’t just about compliance. It’s about protecting controlled data, staying competitive in the procurement process, and ensuring long-term eligibility for defense contracts.

And now, with Scrut supporting CMMC Level 3, organizations can accelerate compliance with the highest tier of requirements for protecting Controlled Unclassified Information (CUI).

What is CMMC and why was it created?

The CMMC was developed by the DoD to safeguard two types of sensitive data: Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). It consolidates existing security requirements and ensures that every contractor in the supply chain meets minimum cybersecurity standards.

The original CMMC framework had five levels, but in 2021, it evolved into CMMC 2.0, a streamlined model with three levels of maturity. The phased rollout of CMMC 2.0 is currently underway, and contractors will increasingly need to demonstrate certification to remain eligible for DoD contracts.

Understanding the CMMC structure

CMMC 2.0 defines three levels of cybersecurity maturity. Each level builds on the previous one, with progressively stringent requirements and assessment processes.

This tiered model allows organizations to scale their cybersecurity practices in line with the sensitivity of information they handle.

Why CMMC Level 3 is critical

CMMC Level 3 is designed for contractors that handle the most sensitive CUI and face heightened risk of cyberattacks. It is often mandatory for organizations bidding on high-value or high-security DoD contracts, making it a differentiator in the competitive defense market.

Timeline note: CMMC Level 3 requirements will begin applying to selected contracts starting in 2027.

While Level 3 is not yet a contractual requirement, for many organizations preparing too early may not be cost-effective. However, laying the groundwork now, by strengthening controls, closing documentation gaps, and aligning policies, signals resilience and maturity. Contractors that invest in readiness ahead of enforcement will be better positioned to meet demanding DoD requirements when the mandate arrives.

Challenges organizations face in achieving Level 3

Reaching CMMC Level 3 is no small feat. Contractors often encounter:

• Complex control mapping from NIST SP 800-171 and 800-172
  
• Extensive policy and plan documentation, including System Security Plans (SSPs)
  
• Evidence collection across multiple systems and tools
  
• Ongoing compliance needs, with reassessments every three years and interim reviews
  

For most organizations, preparing for Level 3 certification can take 12–18 months without automation, delaying contract eligibility and creating resource strain.

How Scrut streamlines your CMMC audit process

Scrut makes CMMC certification less overwhelming with:

• Native framework support for all 3 CMMC levels
  
• Pre-mapped controls to NIST SP 800-171/172
  
• Extensive control library and ready-to-use policy templates, including SSPs
  
• Automated evidence collection from integrations with AWS, Okta, Jira, and more
  
• Continuous monitoring to stay compliant between assessments
  

With Scrut, contractors can replace manual, error-prone processes with automation, speeding up their CMMC journey, reducing audit fatigue, and strengthening confidence in their cybersecurity posture.
