[FAQs About How to Maintain CMMC Compliance](https://www.motherbearsecurity.com/blog/how-to-maintain-cmmc-compliance#FAQs) For [defense contractors](https://www.motherbearsecurity.com/blog/cmmc-for-defense-contractors), achieving Cybersecurity Maturity Model Certification (CMMC) compliance tells the government what was true on the day of assessment. Each year after that, a senior official signs a statement confirming it's still true. That signature is what maintenance actually protects. Under the program's rules, an Affirming Official must affirm continuing compliance after every assessment, including any closeout, and annually thereafter. The affirmation goes into the Supplier Performance Risk System (SPRS) as a formal representation about your organization's current state. This reframes the work. Maintaining [CMMC compliance](https://www.motherbearsecurity.com/blog/what-is-cmmc-compliance) isn't about keeping a certificate warm. It's mostly about making sure the next affirmation is accurate when someone has to sign it. For Department of Defense (DoD) solicitations and contracts that specify a CMMC Status, contract eligibility depends on keeping that status current. DoD contractors bidding on defense contracts feel that directly. This guide covers the recurring obligations by level, what causes compliance to drift, the gap most contractors don't see coming, and the habits that keep an affirmation defensible. ## **TL;DR** - Annual affirmation is the recurring obligation that matters most. Miss it and your status lapses, even inside a valid assessment window. - Level 1 requires an annual self-assessment. Level 2 self-assessment runs every three years, with annual affirmations in between. - A CMMC assessment Plan of Action and Milestones (POA&M) covers eligible NOT MET requirements identified during an assessment. Temporary deficiencies that arise later may instead belong in an operational plan of action. - Scope changes are a common source of drift. New cloud services, contractor access, and network paths added for convenience can move the boundary quietly. - [MotherBear](https://www.motherbearsecurity.com/schedule-demo) keeps requirement status, evidence, and documentation connected between assessments, so the affirmation reflects the environment you actually run. ## **What the CMMC Framework Expects After Your CMMC Assessment** The CMMC framework assesses a point in time. Your organization's security posture doesn't hold still afterward, though your contractual obligation to maintain compliance continues regardless. Achieving CMMC compliance establishes the baseline. Maintenance is the work of keeping that baseline aligned with the environment you actually run. Required security controls stay implemented, documentation stays accurate, evidence stays current, and the assessment scope still describes where [Controlled Unclassified Information](https://www.motherbearsecurity.com/blog/what-is-cui) (CUI) actually lives. That ongoing alignment is what continuous compliance means in practice. You maintain compliance year to year rather than rebuild the program before each cycle. Achieving compliance gets the program into place; maintaining it keeps that program aligned with the environment you actually run. The reason this matters more than it sounds: your annual affirmation asserts continuing compliance with every requirement inside your CMMC assessment scope. It isn't a formality or a renewal fee. It's a representation of present-tense fact. Contractors who treat the years between assessments as quiet time end up affirming a compliance posture they haven't verified. That's a different risk from failing an assessment, and a harder one to explain. ## **The Recurring CMMC Requirements by Level** Your obligations depend on your applicable [CMMC level](https://www.motherbearsecurity.com/blog/cmmc-levels) and assessment type. Confirming the correct CMMC level matters here, since Level 1 covers [Federal Contract Information](https://www.motherbearsecurity.com/blog/what-is-fci) (FCI) while Level 2 covers CUI. The cadence differs by assessment type, but annual compliance affirmations do not. Every organization seeking assessment carries them, whether the verification is a self-assessment or a third-party assessment. | **CMMC Level** | **Assessment Cadence** | **Annual Affirmation** | | --- | --- | --- | | Level 1 (Self) | Annual self-assessment | Required | | Level 2 (Self) | Self-assessment every three years | Required | | Level 2, CMMC Third-Party Assessment Organization (C3PAO) | Certification assessment every three years | Required | | Level 3, Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) | Government assessment every three years, on top of a maintained Final Level 2 (C3PAO) status | Required for both statuses | Two details shape planning. An affirmation is also required at the completion of a POA&M closeout, not only on the annual anniversary. A lapsed affirmation can drop your status even when your assessment remains within its three-year window. One piece of current context. [Phase 2 has been suspended since July 2026](https://www.cmmc.com/newsroom/cmmc-phase-2-suspension), and implementation remains in Phase 1. That phase primarily uses Level 1 (Self) and Level 2 (Self), although the Department may require Level 2 (C3PAO) for an applicable procurement at its discretion. Self-assessment obligations, SPRS submission, and annual affirmations all continue unchanged. ## **CMMC POA&M vs Operational Plan of Action After Assessment** These two artifacts share a purpose and almost nothing else, and understanding the distinction is the most useful thing for maintenance. A CMMC assessment POA&M applies to select requirements scored NOT MET during an assessment, which is why it features so heavily in initial certification work. It's tied to Conditional status, requires a score ratio of at least 0.8, and carries a 180-day closeout. Level 1 doesn't permit one at all. An operational plan of action is different. Defined under [CA.L2-3.12.2](https://ndisac.org/dibscc/cyberassist/cybersecurity-maturity-model-certification/level-2/ca-l2-3-12-2/), it identifies temporary vulnerabilities and temporary deficiencies arising in normal operations, including the updates, patches, and reconfiguration that happen as threats evolve. It carries no fixed remediation timeline, and the organization defines its own format. ### **Why Temporary Deficiencies Aren't Failures** A temporary deficiency is a condition where remediation is feasible, and a known fix is available or in progress. Critically, it arises after implementation rather than during it. The regulation provides a useful example: FIPS-validated cryptography may require a patch, but applying that patch can result in a version that no longer retains its validated status. Nothing was implemented badly; it’s the environment that moved. Here's the part worth knowing. Temporary deficiencies appropriately addressed in an operational plan of action, with deficiency reviews and demonstrated progress toward correction, shall be assessed as MET. That changes how maintenance feels. A patch that temporarily disrupts compliance can be handled as an operational deficiency rather than a CMMC assessment POA&M item, when it meets the temporary-deficiency criteria and is properly documented and tracked. The same logic covers enduring exceptions. Systems that can't meet a requirement for legitimate reasons, described with mitigations in your System Security Plan (SSP), are also assessed as MET, and no operational plan of action is required for them. What doesn't work is leaving deficiencies undocumented. Knowingly affirming compliance while material deficiencies remain can create False Claims Act risk, and the Department of Justice's Civil Cyber-Fraud Initiative specifically targets knowing misrepresentations about cybersecurity compliance. ## **When a Change Requires a New CMMC Assessment** Most maintenance is routine. Some changes aren't, and telling them apart is a maintenance skill in itself. Significant architectural or boundary changes to the previous [CMMC assessment](https://www.motherbearsecurity.com/blog/cmmc-assessment-guide) scope can require a new assessment. When the assessment scope changes, the existing assessment is no longer valid, and a new assessment follows with the applicable affirmation. Three questions separate the categories: - **Did the boundary move?** New systems, locations, or providers handling CUI may change the assessment scope. Adding resources inside the existing assessed boundary doesn't necessarily trigger a new assessment if they follow the existing SSP. - **Did the architecture change materially?** Migrations, consolidations, and significant redesigns affect how requirements are implemented rather than whether they still work. - **Is this temporary or permanent?** A patch pending revalidation is a temporary deficiency. A new cloud platform holding CUI may change the assessment scope. Getting this wrong in either direction costs money. Treating every change as assessment-triggering wastes cycles, and treating a genuine scope change as routine leaves you affirming compliance for an environment nobody assessed. ## **What Actually Causes Compliance Drift** Drift is rarely a decision. It's an accumulation of small operational changes nobody revalidated against the boundary, and it reopens cybersecurity risks and cyber threats the original CMMC implementation was designed to close. ### **Scope Changes Nobody Flagged** A new cloud workload, a contractor granted temporary access that became permanent, a network path opened for a project. Each is reasonable in isolation, and each can move where CUI travels. Scope changes are a common source of drift because they happen through ordinary work rather than through security decisions. The team that added the integration wasn't thinking about your assessment scope, or about where sensitive data would end up. Prime contractors face the same problem down the supply chain, since a subcontractor's scope change can affect the flow-down they rely on. ### **External Service Providers Changing Underneath You** Your providers update their services, change their subprocessors, and adjust their own controls. A responsibility split documented two years ago may no longer describe the arrangement. Review provider documentation and the responsibility matrix on a schedule, and treat a provider change the same way you'd treat an internal one. A cloud service provider that processes, stores, or transmits CUI must use a service offering that is Federal Risk and Authorization Management Program (FedRAMP) Moderate or higher Authorized, or that meets FedRAMP Moderate-equivalent requirements under Department policy. Your own responsibilities stay documented through the SSP and the Customer Responsibility Matrix. Settings like data encryption can change on their side without notice, and you still have to protect Controlled Unclassified Information either way. ### **Personnel Turnover** Controls that depend on one person's habits leave with that person. Access reviews stop happening, log reviews become irregular, and the procedure that described the work no longer matches anyone's routine. This is why named owners matter more than documented processes. A procedure without a current owner is a description of something that used to happen. Cybersecurity awareness training is the other half of it. New staff inherit cybersecurity best practices only if someone teaches them, and training records are evidence an assessor will ask for. ## **Change Management as Your Compliance Program's Backbone** The most reliable maintenance practice is unglamorous: route changes through a review that asks whether the boundary moved. That makes change management one of the most important ongoing compliance efforts after an assessment. Treat your assessed environment as a managed baseline covering in-scope assets, identities, data flows, privileged accounts, logging sources, and third-party connections. Review any change to those elements before implementation, not after discovery. That review needs only three questions. Does this change what's in scope? Does it affect a control that was assessed as MET? Does the documentation describing it need updating? Most changes answer no to all three and proceed. The ones that don't are exactly the ones you needed to catch. ## **Continuous Monitoring and Automated Evidence Collection** At Level 2, [continuous monitoring](https://www.motherbearsecurity.com/blog/continuous-monitoring-for-cmmc-compliance) of security controls is a requirement rather than a maturity option, and evidence of that monitoring is what an assessor examines next cycle. The goal is not only to preserve assessment readiness, but to maintain security as systems, users, and threats change. Automated evidence collection compounds the benefit. Artifacts captured continuously carry accurate dates and reflect the environment as it was, which beats reconstructing a year of activity the month before reassessment. For maintenance purposes, the relevant point is narrower. Monitoring helps temporary deficiencies surface early enough to document and track in an operational plan of action when they meet the criteria, rather than appearing later as assessment findings. It also shortens the path from a suspected issue to incident response. ## **Running Gap Analyses Between Each CMMC Assessment** At Level 2, periodic security control assessment is part of the requirement set. CMMC defines "periodically" as a regular interval that may not exceed one year, which gives you a built-in annual checkpoint for control effectiveness. Run gap analyses against the CMMC standards rather than against last year's results. Comparing your environment to your own previous answers confirms the answers, not the controls. At Level 3, Organization-Defined Parameters (ODPs) appear in selected enhanced security requirements. The Department defines those parameter values rather than the contractor, so maintenance means confirming your environment still meets the prescribed values as cybersecurity threats evolve. Two triggers should prompt an off-cycle review: 1. **Significant system changes**, since those are where drift concentrates. 2. **Security incidents**, because an incident tells you something about a control regardless of whether it was assessed as MET. Test the incident response plan on a schedule too. Data breaches and near misses both reveal whether the documented process matches what people actually do under pressure. Contractors that find their own gaps fix them cheaply. Contractors that wait for a reassessment to surface them are fixing under time pressure, with a signed affirmation already on record. ## **Keeping Documentation Current for the Next Affirmation** Your affirmation attests to continuing compliance with the applicable security requirements. Keeping the SSP and related documentation current makes that claim defensible and prepares you for the next assessment. Treat both as living documents with named owners and review triggers tied to change management. An SSP updated once a year describes a company that existed at some point during that year. The same applies to evidence. Artifacts age at different rates, and an evidence set that proved compliance at assessment may prove very little eighteen months later. Before each affirmation, walk the requirements and ask what changed. That review is short when maintenance has been continuous and long when it hasn't, which tells you something in itself. ## **Where the Cyber AB Fits in the Cybersecurity Maturity Model Certification Ecosystem** The Cyber AB supports the CMMC ecosystem and operates the marketplace where Registered Practitioner Organizations and assessment organizations are listed. In its Accreditation Body role, it authorizes and accredits C3PAOs, while assessor certification runs through the CMMC Assessor and Instructor Certification Organization (CAICO) function. For maintenance purposes, that ecosystem matters in two ways. Compliance experts can run readiness reviews and mock assessments between cycles, which is often the cheapest way to find drift. For a Level 2 certification assessment, a provider that served as a consultant preparing the organization within the previous three years cannot participate in that certification assessment. For contractors handling CUI in the Defense Industrial Base (DIB), those relationships matter more as obligations grow, especially when CMMC status affects eligibility for DoD contracts. Level 3 exists for defense sector work facing advanced persistent threats and national security implications, though most organizations never encounter it. When scope questions turn on contract language, the contracting officer is the one who can settle them. Consultancies supporting several contractors face a version of this at scale, since maintenance work runs continuously throughout every client program rather than concentrating around one assessment date. ## **Keep Your Affirmation Defensible With MotherBear** The affirmation asks a simple question: is this still true? Answering it confidently requires knowing what changed since the last time you looked. That's difficult when requirement status sits in one system, evidence in another, and documentation in a third. Nothing connects them, so nothing signals when they stop agreeing. ![](https://www.motherbearsecurity.com/hs-fs/hubfs/undefined-Jun-18-2026-11-13-38-9425-AM.png?width=1833&height=777&name=undefined-Jun-18-2026-11-13-38-9425-AM.png) [MotherBear](https://www.motherbearsecurity.com/) holds them together. Requirement status, the evidence supporting each one, SSP and policy material, and remediation tasks with owners live in the same workspace, so drift surfaces as a visible gap rather than a quiet one. For consultants maintaining programs for several contractors, that shared structure is what makes annual affirmation season a review rather than a scramble.

Level 1 requires a fresh self-assessment every year. The three-year window is conditional rather than automatic. Missing an annual affirmation can cause your status to lapse even when the assessment remains current, which is why the affirmation date deserves its own calendar entry. ### **How much does CMMC compliance cost to maintain?** There's no standard maintenance cost. It depends on scope, how much the environment changes, internal staffing, tooling, external providers, and how much remediation accumulates between reviews. The recurring items are internal review time, evidence collection, documentation updates, and any advisory support you retain. Programs that maintain continuously tend to spread that effort evenly; programs that don't concentrate it before reassessment. ### **Is CMMC compliance difficult to maintain?** The difficulty is consistency rather than complexity. No individual maintenance task is hard, but doing them reliably while the business changes around you takes discipline that initial achievement doesn't require. Organizations that build maintenance into existing routines, through change management and scheduled reviews, find it manageable. Those treating it as an annual event find it expensive. ### **What is the best software for CMMC compliance?** The right platform depends on how many frameworks you carry. Organizations managing several compliance programs benefit from broad governance tools, while contractors focused on CMMC generally move faster with a purpose-built platform. For maintenance specifically, what matters is whether requirement status, evidence, and documentation stay connected, since that connection is what makes drift visible before it reaches an affirmation. ## Need help with CMMC compliance?
