Experienced, independent, and easy to work with. We're an Authorized C3PAO by Cyber AB. Our approach identifies issues as soon as possible — well before your CMMC Detailed Mock Assessment and long before your formal certification assessment.
123 Efficient CMMC, LLC is authorized by Cyber AB as a Certified Third-Party Assessment Organization (C3PAO), giving us standing to conduct CMMC Detailed Mock Assessments and formal CMMC C3PAO Certification Assessments for organizations seeking CMMC Level 2 certification. Our assessors hold LCCA (Lead CMMC Certified Assessor) and CCA (CMMC Certified Assessor) credentials — and 123 CMMC has gone through its own CMMC Level 2 certification.

Most organizations start with a Complimentary CMMC Readiness Spot Check — a focused, no-cost, independent review that identifies issues as soon as possible, well before the CMMC Detailed Mock Assessment and long before the certification assessment. Fewer surprises, sooner — not on the day it counts most.
For both the CMMC Detailed Mock Assessment and the CMMC C3PAO Certification Assessment, we request applicable documentation and evidence about one week beforehand and begin reviewing it in advance. That's what lets scheduled assessment sessions focus on interviews, demonstrations, clarifications, and testing — rather than spending multiple days reviewing documents from scratch. Less time in meetings. More done before and after.
TIMELINE: 1–2 DAYS
Our CMMC Detailed Mock Assessment evaluates all 320 CMMC Level 2 assessment objectives and provides visibility into what is MET, NOT MET, or NOT APPLICABLE, based on the evidence evaluated — a genuinely detailed rehearsal against the real standard, not a surface-level walkthrough. The 1–2 day timeline covers scheduled interviews and testing; we review your evidence in advance so that time is used efficiently. Where operationally appropriate, the same assessors who conduct your CMMC Detailed Mock Assessment may also participate in your later CMMC C3PAO Certification Assessment.
Our assessment team holds credentials across security, audit, and compliance disciplines — the depth it takes to assess thoroughly without cutting corners. Already working with a cybersecurity consultant, Registered Provider Organization, managed service provider, managed security service provider, or internal security team? We work alongside the team already supporting your organization while conducting our CMMC assessment services.

Not right now. On July 13, 2026, the Department of War suspended CMMC Phase II, so a Level 2 (C3PAO) certification assessment is voluntary during the suspension. The baseline obligations still apply: CMMC Level 1 and Level 2 self-assessments where your contracts call for them, posting your score in the Supplier Performance Risk System (SPRS), and DFARS 252.204-7012 with the NIST SP 800-171 requirements. Some primes and customers still ask for third-party certification. See our guide, Level 2 Self vs C3PAO. If a prime is asking, see what subcontractors should confirm with their prime.
Most organizations start with a Complimentary CMMC Readiness Spot Check, then offer a CMMC Detailed Mock Assessment that evaluates all 320 Level 2 assessment objectives before you move into the formal CMMC C3PAO Certification Assessment. We also offer an independent review of your self-assessment before SPRS submission. We request evidence about a week in advance and review it before the live sessions, which keeps scheduled assessment time efficient. Our assessment team holds credentials across security, audit, and compliance disciplines.
The Complimentary CMMC Readiness Spot Check takes 1 day, the CMMC Detailed Mock Assessment takes 1–2 days, and the CMMC C3PAO Certification Assessment involves 1–2 days of scheduled interviews. Your actual total time to certification depends on your assessment scope, scheduling, the evidence available, any findings that need to be addressed, and quality review and administrative processing after the live sessions.
Depending on your environment and assessment scope, the Spot Check may review your System Security Plan, Plan of Action & Milestones, information security policies and procedures, Security Assessment Report, ongoing security monitoring, Supplier Performance Risk System information where applicable, and your CUI asset inventory and assessment scope. See our Complimentary CMMC Readiness Spot Check page for the full list.
Yes. Many of the organizations we assess already work with a cybersecurity consultant, Registered Provider Organization, managed service provider, or managed security service provider. We can work with the team already supporting your organization while we conduct the Complimentary CMMC Readiness Spot Check, an independent pre-SPRS review, the CMMC Detailed Mock Assessment, or the formal CMMC C3PAO Certification Assessment.

A C3PAO is a CMMC Third-Party Assessment Organization. It is the only kind of company that can run a CMMC Level 2 certification assessment. The rules for C3PAOs are set out in 32 CFR Part 170. The Cyber AB authorizes each one. A C3PAO cannot assess a company it helped get ready. 123 CMMC is an Authorized C3PAO. We do not provide implementation consulting to organizations we assess. That keeps the review independent. You can check any C3PAO’s status in the Cyber AB Marketplace before you sign. Ask which services the firm offers and who will do the work.
CMMC Level 2 is the level for companies that handle Controlled Unclassified Information (CUI). It covers the 110 security requirements in NIST SP 800-171 Revision 2. An assessor checks those requirements against 320 assessment objectives. A company can meet Level 2 by self-assessment or by a C3PAO assessment, which leads to Level 2 (C3PAO) status. Scores from either path are posted in the Supplier Performance Risk System (SPRS). Your contract, or your prime, decides which path you need. The security work is the same either way.
Not for new DoD awards. According to the July 13, 2026 Department of War memo, Phase II is suspended. During the suspension, solicitations may require only Level 1 (Self) or Level 2 (Self). C3PAO certification is voluntary, and many primes still ask for it. DFARS 252.204-7012 still applies. So do your self-assessment and your SPRS score. If a prime or customer wants third-party proof, you can still book a C3PAO assessment today. Ask your prime to state its requirement in writing.
DFARS Class Deviation 2026-O0025, Revision 3 (September 3, 2026) sets November 10, 2028 as the date the CMMC clause goes into contracts broadly when systems handle FCI or CUI. It is a contract-clause date. It is not a Phase II restart, and a class deviation can be revised. Until then, the clause is used only when a program office names a CMMC level. Many companies use the time to close gaps, check their SSP, and plan a voluntary assessment.
