C3PAOs, or Certified Third-Party Assessment Organizations, are U.S.-owned firms accredited by Cyber-AB (the CMMC Accreditation Body) to conduct independent, official CMMC Level 2 assessments for DoD contractors handling CUI. They verify 110 NIST SP 800-171 controls through staff interviews, evidence review and technical testing, then submit results to Cyber-AB for 3-year certification approval essential for bidding on DFARS 7012/7019/7020 contracts.
Armada’s C3PAO Support Confirmed
Armada Cyber Defense supports clients through evaluating, negotiating, and partnering with C3PAOs as part of their six-step Unified Framework, acting as a Cyber-AB RPO to handle onboarding, gaps, remediation, mocks, and audit coordination without performing assessments themselves.
Armada help clients navigate this process by:
- Identification Process: They identify active C3PAOs from Cyber-AB’s Marketplace with experience in your setup, responsiveness and track record via reviews/client feedback.
- Cost and Terms Evaluation: Armada reviews engagement models ($50K-$150K+ typical audits), fixed vs. time/materials, add-ons (readiness reviews), and terms to fit budgets that often bundling with their mock audits for savings.
- Scheduling Coordination: They align C3PAO availability (3-12 month waits common) with your milestones, using CyberComply’s Audit Readiness Mode for timing mocks and evidence handoff.
- Conflict Safeguards: Vetting ensures no prior implementation work by the C3PAO (per Cyber-AB rules), leveraging Armada’s independence as non-assessor.
- Pre-Assessment Prep: Facilitates readiness via CyberGap gaps, CyberComply remediation/tracking, and simulated audits to avoid rework, part of their six-step framework (onboarding to audit support).
Function of C3PAOs
C3PAOs (Certified Third-Party Assessment Organizations) conduct official CMMC Level 2 assessments to verify DoD contractors’ compliance with NIST SP 800-171 controls for protecting CUI.
- Formal Assessments: Perform independent audits using examine (artifacts review), interview (personnel discussions), and test (technical validation) methods across 110 controls, typically spanning 3-10 days on-site or hybrid.
- Employ Certified Staff: Utilize CCAs (Certified CMMC Assessors), CCPs (Certified CMMC Professionals), and RPs under Cyber-AB guidelines to ensure qualified, impartial execution.
- Results Submission: Compile Security Assessment Reports (SARs), POA&Ms, and scores; submit to DoD’s eMASS for Cyber-AB review and 3-year certification issuance.
- Cyber-AB Oversight: Adhere to the Code of Professional Conduct, standardized procedures, and routine audits for consistency and quality.
Key Requirements
Accreditation and DoD Clearance
C3PAOs require full Cyber-AB accreditation (Stages 1-3: application, risk/FOCI review, DIBCAC Level 2 self-cert) plus DoD-adjudicated clearance, typically DCSA Facility Security Clearance (FCL) ensuring U.S. control and personnel vetting.
Qualified Staff and Procedures
They must employ certified staff and maintain documented procedures compliant with ISO/IEC 17020 that includes quality assurance (audit trails, training), information protection (CUI safeguards, no-storage policies), and standardized assessment methodology (examine/interview/test per CMMC guides).
Summary
C3PAOs are independent auditors approved by Cyber-AB to check if DoD contractors meet CMMC Level 2 rules for protecting sensitive data. They do formal audits by reviewing papers, talking to staff, and testing systems against 110 security controls, then send results to the government for a 3-year certification.
To qualify, they need Cyber-AB okay, DoD security clearance, trained experts like CCAs, and strict rules for fairness and quality, no helping the same company they audit. RPOs like Armada help pick and prep for these auditors using tools like CyberGap and CyberComply.
