During a CMMC Level 2 assessment, the OSC’s Assessment Official asks the Lead Assessor if they can provide a list of recommended vendors to improve…

The CMMC Code of Professional Conduct (CoPC) strictly prohibits CMMC Third-Party Assessor Organizations (C3PAOs) and their assessors from providing consulting services to an Organization Seeking Certification (OSC) that they are also assessing. Recommending specific vendors constitutes a form of consulting and creates a significant conflict of interest (CoI). This action would compromise the objectivity and impartiality required for the assessment. The Lead Assessor's professional obligation is to politely decline the request and explain that this prohibition is a core tenet of the CoPC, ensuring the integrity and independence of the CMMC assessment process.

A. Providing the list after the assessment does not mitigate the conflict of interest; it is still a prohibited consulting activity between the assessor and the assessed entity.

C. Offering "general guidance" on vendor selection still crosses the line into consulting, which is explicitly forbidden to maintain the assessor's impartiality and objectivity.

D. The Cyber AB would not approve such a request, as it represents a fundamental violation of the CoPC and the principles of third-party assessment independence.

1. The Cyber AB, Code of Professional Conduct, Version 2.2, December 2022.

Canon 4: Objectivity, Rule 4.2: "CMMC Professionals shall not provide CMMC consulting services to any OSC for which they also provide CMMC assessment services. This is a conflict of interest." (Page 6). This rule directly forbids the action of providing vendor recommendations, which is a consulting activity.

2. The Cyber AB, CMMC Assessment Process (CAP) for CMMC Level 2, Version 1.0, July 2023.

Section 2.3.1, C3PAO Responsibilities: This section outlines that C3PAOs must "Adhere to the requirements of ISO/IEC 17021-1," which includes the fundamental principle of impartiality. Providing vendor recommendations would violate this principle. (Page 10).

3. ISO/IEC 17021-1:2015, Conformity assessment — Requirements for bodies providing audit and certification of management systems — Part 1: Requirements.

Section 5.2, Impartiality: This standard, which C3PAOs must adhere to, heavily emphasizes the need to manage conflicts of interest and ensure impartiality. Section 5.2.5 specifically states that a certification body (in this case, a C3PAO) shall not provide management system consultancy. Recommending vendors falls under this prohibited category.
