Section A: About CMMC

Posted on Dec 15 / 2025

As a trusted Registered Provider Organization (RPO) for CMMC 2.0, Echelon is committed to simplifying compliance and protecting your DoD contracts. With the CMMC requirements now rolling out in phases from 2025 through 2028, defense contractors need clear, authoritative answers to remain eligible for future opportunities.

To support your journey from readiness to certification, we have structured the official guidance from the DoD CIO's CMMC Frequently Asked Questions into this essential five-part series.

We will break down the most critical rules, timelines, and requirements across the following sections: About CMMC, The CMMC Model, Assessments, Implementation, and External Service Providers (ESPs), helping you align with NIST 800-171 and achieve a smooth certification with our C3PAO partners.

A-Q1. When will Cybersecurity Maturity Model Certification (CMMC) assessments be required for Department contracts?

A-A1. The Department will begin to incorporate CMMC assessment requirements in applicable procurements on November 10, 2025, when the revised Defense Federal Acquisition Regulation Supplement (DFARS) clause 252.204-7021 becomes effective. The first 12 months of implementation will primarily focus on self-assessments. For further information on the Department’s phased implementation plan, please see 32 Code of Federal Regulations (CFR) 170.3(e)

A-Q2. How much will it cost to achieve CMMC compliance?

A-A2. Costs incurred to implement existing contract requirements for safeguarding information (e.g., DFARS 252.204-7012) are not considered part of the CMMC compliance cost. However, the cost of achieving CMMC compliance (i.e., self-assessment or certification) depends on various factors, including, but not limited to, the CMMC level required, the complexity of the defense industrial base (DIB) company’s unclassified network, the existing cybersecurity posture of the organization, and market forces of supply and demand.

Echelon Take:

The key to controlling compliance cost is managing the complexity and posture of your environment, the two biggest variables mentioned by the DoD.

As a certified CMMC Registered Provider Organization (RPO), Echelon helps contractors stabilize these variables by first performing a detailed Scope Definition to establish the smallest necessary boundary, followed by a Gap Assessment to clearly map your current security state against the NIST 800-171 requirements. This essential first step removes uncertainty and creates the foundational roadmap needed to budget accurately and proceed confidently toward certification.

We understand that you need a predictable investment plan, not vague estimates. To define a clear CMMC boundary and get a reliable plan, we encourage you to initiate a Scope Definition with our team to map out your compliance journey.

A-Q3. What resources are available to assist companies in complying with Department cybersecurity requirements?

A-A3. The Department provides resources to help businesses who wish to enter the DIB reach cybersecurity compliance.

• The DoW CIO DIB Cybersecurity Program has compiled a list of no-cost Cybersecurity-as-a-Service resources to reduce barriers to DIB community compliance and support contract cybersecurity efforts at dibnet.dod.mil under DoD DIB Cybersecurity-As-A-Service (CSaaS) Services and Support.

• The CMMC Accreditation Body, currently the Cyber AB, has a marketplace of certified CMMC assessors, professionals, and registered practitioner organizations that companies can engage now to prepare for CMMC implementation: https://cyberab.org/marketplace

• The Defense Acquisition University offers free online CMMC and cybersecurity training: https://www.dau.edu/cybersecurity/training

• The Defense Acquisition University also offers a drop-down for CMMC web events: https://www.dau.edu/cybersecurity/cyber-solutions

A-Q4. Who is the point of contact for general inquiries regarding the CMMC Program?

A-A4. General inquiries regarding the CMMC Program, model, or policy can be directed to the CMMC Program Management Office using the contact form on our website: https://dodcio.defense.gov/cmmc/Contact/.

Inquiries regarding CMMC Registered Practitioner (RP/RPA) and CMMC Third-Party Assessment Organization (C3PAO) application status should be directed to the CMMC Accreditation Body, currently the Cyber AB, at [email protected], or to the specific point of contact the individual has communicated with about the application process thus far.

Inquiries regarding CMMC Certified Professional (CCP) or CMMC Certified Assessor (CCA) application status should be directed to the Cybersecurity Assessor and Instructor Certification Organization (CAICO), at [email protected], or to the specific point of contact the individual has communicated with about the application process thus far.

Having addressed foundational questions regarding the CMMC implementation timeline and the variable costs of compliance in this initial section, the next logical step is to understand the structural basis of the program.

In Part 2: The CMMC Model, we will clarify the relationship between the CMMC Levels and the foundational security standard, NIST SP 800-171, required for protecting Controlled Unclassified Information (CUI).
