CMMC-Ready SOC Providers

Providers indicating CMMC support. Confirm evidence, retention, data location, and reporting.

How to use this list

Use it when

Use this list when a framework requirement affects your SOC provider shortlist.

Do not assume

Compliance support is not the same as audit readiness for your exact environment, evidence needs, or data location.

Ask before shortlisting

  1. Ask for the actual evidence package, not just the compliance logo.
  2. Confirm data processing locations, retention, and audit-ready reporting.
  3. Check whether the provider can support your framework without a custom services project.
Category background

These SOC providers support CMMC (Cybersecurity Maturity Model Certification) compliance for defense contractors and the Defense Industrial Base (DIB). As CMMC 2.0 enforcement ramps up, organizations handling Controlled Unclassified Information (CUI) need SOC providers that understand the specific requirements of NIST 800-171 and can deliver the continuous monitoring capabilities DoD expects.

CMMC and Continuous Monitoring

CMMC Level 2 requires implementation of all 110 controls in NIST 800-171, many of which directly relate to SOC operations: audit event review, incident response, security assessment, and system monitoring. A CMMC-capable SOC provider does not just monitor for threats — they generate the compliance evidence and documentation needed for CMMC assessments, including audit logs, incident reports, and security posture assessments mapped to specific NIST 800-171 control families.

Choosing a SOC Provider for CMMC

Defense contractors should verify that their SOC provider can handle CUI within appropriate security boundaries, provide documentation that maps to NIST 800-171 controls, support the organization’s Plan of Action and Milestones (POA&M), and maintain evidence for CMMC assessment readiness. Providers with FedRAMP authorization or their own CMMC certification offer additional assurance.

Questions

What is CMMC and who needs it?
The Cybersecurity Maturity Model Certification (CMMC) is a Department of Defense requirement for all contractors and subcontractors that handle Controlled Unclassified Information (CUI) or Federal Contract Information (FCI). CMMC 2.0 has three levels, with Level 2 requiring implementation of all 110 NIST 800-171 controls and a third-party assessment. Contractors that fail to achieve the required CMMC level will be ineligible for DoD contracts.
How do SOC providers help with CMMC compliance?
SOC providers help with CMMC by delivering continuous monitoring capabilities required by NIST 800-171 controls, including audit log collection and review (3.3.x), incident response (3.6.x), security assessment (3.12.x), and system and communications protection (3.13.x). They also provide evidence documentation for CMMC assessments and ongoing compliance monitoring between assessment cycles.
Do I need a CMMC-certified SOC provider?
Your SOC provider does not need to be CMMC-certified themselves, but they must operate in a way that does not compromise your CMMC compliance. This means they should handle CUI appropriately, operate within FedRAMP or equivalent security boundaries, and be willing to be included in your System Security Plan (SSP) as an external service provider. Some SOC providers have achieved their own CMMC certification, which simplifies compliance.
