Navigating POA&M Requirements for CMMC & FedRAMP: From Assessment to Audit

Key Takeaways

• POA&Ms provide a formal structure for documenting security gaps and outlining how they will be remediated.
  
• CMMC limits POA&Ms to specific practices and requires all items to be closed within 180 days.
  
• FedRAMP integrates POA&Ms into continuous monitoring with monthly updates and evidence-based closure.
  
• Strong POA&Ms include clear descriptions, assigned ownership, realistic milestones, and defined evidence.
  
• The quality and clarity of POA&M entries influence assessment outcomes in both frameworks.

Understanding POA&Ms

A Plan of Action & Milestones (POA&M) is used when a required control or practice is not fully implemented at the time of review, and the framework permits deferring that issue. Some deficiencies may be addressed through POA&Ms; others must be resolved before the assessment can proceed. The distinction depends on the framework’s rules and the risk associated with the specific POAM requirement. Federal assessors rely on POA&Ms to understand how an organization manages known security gaps.

Why POA&Ms Are Built Into Federal Frameworks

Federal programs know full well that organizations rarely enter an assessment with every requirement fully implemented. POA&Ms provide a formal mechanism for documenting gaps while keeping an eye on ongoing remediation progress. This structure balances practical operational realities with the need for measurable accountability.

POA&Ms help assessors determine whether the organization understands the issue, whether the planned corrective actions are appropriate, and whether timelines are achievable. A well-maintained POA&M indicates operational discipline.

How CMMC and FedRAMP Approach POA&Ms Differently

Although CMMC and FedRAMP both use POA&Ms as part of their compliance model, they do so for different purposes and with different expectations. Understanding this distinction is essential because organizations often assume the frameworks treat POA&Ms the same way.

CMMC

CMMC uses POA&Ms selectively. Only certain practices may be deferred, and even those are subject to strict conditions:

• The organization must meet a minimum score before any deferrals are allowed.
  
• Only practices listed as eligible for POA&Ms can be deferred.
  
• High-impact requirements (such as MFA, encryption, and auditing) cannot appear on a POA&M under any circumstances.
  
• All POA&M items must be closed within 180 days.
  

The purpose of this structure is to prevent organizations from relying on POA&Ms to compensate for foundational gaps. CMMC treats POA&Ms as short-term remediation plans, used only to finalize the last remaining items after the core of the program is already implemented. They are not intended to remain open for extended periods, nor to cover major security controls.

FedRAMP

FedRAMP incorporates POA&Ms into the entire lifecycle of authorization. Instead of being a mechanism for deferring a small number of controls, the POA&M functions as the central record of all identified weaknesses and how they are being addressed over time.

Key elements of this model include:

• Monthly updates to the POA&M as part of continuous monitoring.
  
• Required submission of monthly scan results and any new findings added to the POA&M.
  
• Use of the standardized FedRAMP POAM template to ensure consistency across providers.
  
• Evidence-based closure, meaning that findings are not considered resolved until validated by testing or review.
  

How to Navigate POA&M Requirements Under CMMC and FedRAMP

How CMMC Defines What May Be Deferred

CMMC limits POA&M use to a specific subset of practices. At Level 2, only 51 practices are eligible to be deferred. All remaining practices must be fully implemented before assessment.

Additional CMMC conditions include:

• A minimum score of 80 out of 110 is required before POA&M items can be applied.
  
• High-impact practices cannot be placed on a POA&M.
  
• Each POA&M item must include cost information, defined milestones, and a scheduled completion date.
  
• All POA&M items must be closed within 180 days, without exception.
  

Assessors report consistent challenges where organizations attempt to defer prohibited requirements or submit POA&Ms with insufficient detail. These errors create avoidable delays and can jeopardize eligibility for certification.

How FedRAMP Structures POA&M Requirements

FedRAMP embeds POA&Ms into the ongoing lifecycle of authorization, reflecting its emphasis on continuous monitoring.

Key FedRAMP expectations include:

Required use of the official POA&M template

FedRAMP mandates a standardized template that includes fields for the weakness, the affected system component, severity, source of discovery, planned remediation steps, milestones, testing results, and evidence.

Mandatory monthly updates

Cloud service providers must:

• Update the POA&M every month
  
• Submit monthly scan results (operating system, database, web application, and container scans)
  
• Provide evidence for any items marked as closed
  

Conditions for long-lived POA&M items

Certain weaknesses may remain open for extended periods if categorized as “Operational Requirements,” typically involving complex modernization efforts. These items must still show documented movement each month.

Defined remediation timelines

• High-risk findings must be addressed within 30 days
  
• Medium-risk findings within 90 days
  
• Low-risk findings within 365 days
  

These timelines are widely regarded as one of the most rigorous aspects of FedRAMP compliance.

Evidence-based closure

FedRAMP requires verifiable evidence before an item can be formally closed. This ensures that remediation is both implemented and validated.

Why Requirements Have Tightened

Both frameworks revised their POA&M rules in response to recurring patterns:

• CMMC strengthened its restrictions to reduce over-reliance on deferrals and promote full implementation.
  
• FedRAMP expanded its continuous monitoring expectations to ensure that identified weaknesses do not remain open indefinitely without measurable progress.

Why Organizations Use Centraleyes for CMMC Certification

CMMC readiness requires structured documentation, reliable evidence collection, and consistent oversight across all practices. The Centraleyes platform supports this by automating the core activities that typically slow organizations down during preparation and assessment.

Centraleyes streamlines System Security Plans (SSPs), SPRS score reports, and POA&Ms by generating them directly from live control data. This reduces manual effort, improves accuracy, and ensures alignment with the most recent CMMC requirements. Deficiencies are identified within the platform, allowing teams to assign ownership, establish milestones, and monitor remediation progress in real time.

The platform also supports distributed teams by providing unified dashboards, clear remediation workflows, and visibility into open items, completed work, and upcoming deadlines. For organizations managing multiple business units or clients, Centraleyes offers oversight from a single dashboard, making it possible to track progress across entities without duplicating effort.

For organizations seeking an end-to-end compliance path, Centraleyes+ includes direct collaboration with certified auditors. This allows teams to move from preparation to audit within an integrated environment that supports both readiness and formal assessment.

Frequently Asked Questions

Are POA&Ms optional in CMMC or FedRAMP?

No. If a framework permits a gap to be deferred, the POA&M becomes the required method for documenting and tracking remediation. In FedRAMP, POA&Ms are mandatory for continuous monitoring, even when all controls are implemented, because new findings appear through scans and assessments.

Does the presence of POA&M items automatically reduce an organization’s score?

Under CMMC, deferred items affect the score because the underlying practices are not yet implemented. FedRAMP does not use a scoring model, but open POA&M items must be managed carefully to remain within required remediation timelines. The impact comes from program rules, not the POA&M itself.

Can organizations negotiate longer timelines with assessors?

No. Both CMMC and FedRAMP have fixed timelines for closure. Assessors cannot extend them. If remediation requires more time, the root cause usually points to broader implementation challenges that need to be addressed before assessment.

Are POA&Ms only for technical vulnerabilities?

No. POA&Ms may cover documentation gaps, process weaknesses, or missing control implementations. The key requirement is that the issue must relate to a control or practice defined in the framework and must be eligible for deferral.

Does every security finding need to appear on a POA&M?

Only findings that fall under the framework’s standards. For FedRAMP, all scan findings and assessment-identified weaknesses must appear on the POA&M. For CMMC, the list is limited to authorized practices; prohibited practices may not be deferred and must be implemented before certification.

Who is responsible for maintaining the POA&M?

Organizations typically assign ownership to a compliance lead or security manager, but each POA&M item must have an individual owner responsible for execution. FedRAMP also requires organizations to work with their 3PAO and the government reviewer to validate updates.

Do POA&Ms carry legal or contractual implications?

Yes. For organizations operating under federal contracts, POA&Ms may be reviewed during audits, investigations, or disputes. Misrepresentation or incomplete reporting can introduce legal or contractual risk. Documentation should accurately reflect the organization’s actual remediation status.

What happens if a POA&M item is not closed on time?

In CMMC, failure to close items within 180 days can jeopardize eligibility for certification. In FedRAMP, overdue items may trigger required corrective action plans, additional scrutiny, or, in some severe cases, risk to the authorization.

Is there an advantage to closing a POA&M items ahead of schedule?

Yes. Early closure demonstrates the ability to manage remediation efficiently and signals operational maturity to assessors. It also reduces the administrative burden of monthly updates in FedRAMP.
