CMMC Level 2 is where defense contractors handling Controlled Unclassified Information face substantial obligations. It requires implementing the 110 security controls of NIST SP 800-171 across your environment, documenting them, and - for many contractors - passing a third-party assessment. Understanding what Level 2 demands is essential for any contractor handling CUI.
Book a 15-minute review →The core of Level 2 is the 110 NIST SP 800-171 controls. These span 14 families - access control, audit and accountability, incident response, system and communications protection, and more - covering the practices needed to protect CUI. Meeting Level 2 means implementing all applicable controls, not a subset.
Documentation is integral, not separate. Level 2 requires a System Security Plan (SSP) describing how you meet each control and, where you fall short, a Plan of Action and Milestones (POA&M) for remediation. This documentation is central to assessment - an assessor examines whether your controls are implemented as described.
Assessment is the validation step. For contractors handling CUI on many contracts, Level 2 requires assessment by an authorized third party (C3PAO) rather than self-assessment, adding the assessment-ecosystem and backlog considerations. The assessment validates that your controls are genuinely implemented and evidenced.
Continuous monitoring and evidence directly support meeting and demonstrating the Level 2 controls. MDRwatchdog provides readiness and evidence, not certification. Certification is issued only by an authorized body (for example, a C3PAO for CMMC or a licensed CPA firm for SOC 2). Confirm your specific assessment requirements. This is general information, not legal advice; confirm your specific obligations with qualified counsel.

MDRwatchdog provides security monitoring and compliance evidence to support readiness. It is not a certification and not legal advice. Certification and formal audits are performed by the appropriate authorized bodies (a C3PAO for CMMC, a licensed CPA firm for SOC 2, an accredited body for ISO 27001).
