There’s a pattern that plays out across the defense industrial base every few years. A contractor wins a covered contract, realizes CMMC compliance is now a requirement, and launches an all-hands scramble to get audit-ready. Consultants come in. Controls get documented. Policies get written and signed. The assessment passes — or passes with a remediation plan attached — and then the program quietly winds down until the next assessment cycle approaches.
This is compliance theater. It produces documentation that reflects a single point in time, not the actual security posture of the organization. Assessors are increasingly good at recognizing it. And more importantly, it doesn’t protect the controlled unclassified information that the entire framework exists to safeguard.
The alternative — building a compliance program that runs continuously rather than cyclically — is harder to stand up but dramatically easier to live with. It costs less over time, produces fewer assessment surprises, and actually makes the organization more secure rather than just more audit-ready.
Why the Assessment-Sprint Model Fails Defense Contractors
The assessment-sprint model is understandable from an organizational psychology standpoint. Compliance feels abstract until there’s a deadline attached to it. Resources get allocated toward urgent things, and a CMMC assessment that’s two years away rarely feels urgent enough to sustain momentum.
The problem is that the model produces environments that are technically compliant for a few weeks and genuinely compliant for none of the time in between. Controls get implemented to satisfy requirements rather than to function as real security measures. Policies get signed by employees who were never trained on them. Vulnerability remediation happens in bursts before the assessment window and then stalls until the next cycle.
When something goes wrong in that window — a ransomware incident, a data breach, a CUI spillage — the organization discovers that its documented controls were never fully operational. The incident response plan was a document, not a practiced capability. The access reviews were done once and then abandoned. The monitoring was configured but no one was actually watching the alerts.
Cybersecurity done correctly is a continuous operational discipline, not a project with a start and end date. The same is true for CMMC compliance. Organizations that build it as a program — with ongoing responsibilities, regular cadence, and integrated operational processes — are the ones that pass assessments without drama and recover faster when incidents occur.
What a Continuous Compliance Program Actually Looks Like
A continuous compliance program doesn’t mean every control is being actively tested every day. It means that the activities required to maintain compliance are embedded into normal operations rather than treated as separate compliance tasks that only happen when an assessment is approaching.
The distinction matters because it changes who owns compliance. In a sprint model, compliance is something the IT team or an outside consultant does to the organization periodically. In a continuous model, compliance is something the organization does as part of running itself — with IT, security, operations, and leadership each carrying defined responsibilities throughout the year.
At a structural level, a continuous program has several components that don’t exist or only exist on paper in the sprint model: an internal audit function that actually runs on schedule, a configuration management process that connects every system change to an updated control record, a training program that reaches every relevant employee annually rather than during assessment prep, and a metrics framework that gives leadership meaningful visibility into compliance posture at any point in time rather than only when a report is being prepared.
The NIST SP 800-171 control framework that underpins CMMC Level 2 was designed with continuous operation in mind. The controls aren’t a checklist to be satisfied once — they’re a set of ongoing practices. Access control reviews, audit log monitoring, incident response activities, configuration management — these are verbs, not nouns. They describe things an organization does, continuously, not things it has.
Building the Internal Audit Cadence
One of the clearest markers of a mature continuous compliance program is a functioning internal audit cadence — a scheduled, recurring process of reviewing controls against implementation, identifying gaps, and tracking remediation. Not an annual panic before the C3PAO arrives, but a quarterly or semi-annual cycle that keeps the organization honest about where it actually stands.
Internal audits in a CMMC context don’t need to replicate the full formality of a C3PAO assessment. What they need to do is cover enough ground to surface drift — places where the documented control no longer reflects the operational reality, where a configuration was changed without updating the System Security Plan, where a vendor relationship changed scope without triggering a review of the relevant controls.
The output of an internal audit isn’t a score. It’s a prioritized list of gaps and a timeline for addressing them. If that list is addressed before the external assessment, the assessment becomes a confirmation rather than a discovery exercise. If the list grows unchecked between internal audits, it becomes the finding that delays certification.
This is also where a co-managed IT arrangement can carry significant weight. An internal team that’s also responsible for day-to-day operations has a natural blind spot — they’re close to the environment and often can’t see drift that an outside eye would catch immediately. A co-managed partner who participates in quarterly compliance reviews brings that external perspective without the full cost of an independent audit engagement every quarter.
The Role of Continuous Monitoring in Compliance Maintenance
Continuous monitoring is one of those CMMC requirements that’s easy to implement on paper and genuinely difficult to implement in practice. Having a SIEM configured and running is not the same as having a monitoring program. The difference is whether someone is actually reviewing alerts, whether those alerts are tuned to surface meaningful events rather than noise, and whether there’s a defined process for escalating and responding to what the monitoring surfaces.
CMMC’s Audit and Accountability practice domain requires organizations to generate, protect, and review audit logs. The review requirement is where most organizations fall short in a sprint model — logs exist, but nobody looked at them between assessments. In a continuous model, log review is a scheduled operational activity with documented results and a defined escalation path.
The same logic applies to vulnerability management. NIST’s continuous monitoring guidance treats vulnerability scanning and remediation as an ongoing cycle, not a periodic event. Scanning quarterly and patching when findings can no longer be ignored isn’t continuous monitoring — it’s periodic monitoring with a generous tolerance for risk. A continuous model scans regularly, prioritizes findings by risk, and tracks remediation against documented SLAs.
For organizations that lack the internal staff to run a genuine monitoring operation, a managed IT services provider with a security operations function can fill that gap — provided they’re operating within the CMMC-scoped environment and meeting the security requirements that apply to vendors in that scope. Our earlier piece on the hidden risks of third-party vendors and CMMC compliance is worth revisiting before bringing any monitoring vendor into the CUI environment.
Training as a Compliance Activity, Not a One-Time Checkbox
Security awareness training is CMMC requirement AT.L2-3.2.1, and like most of the framework’s people-focused controls, it’s one that sprint-model organizations typically satisfy with a training event that happens during assessment preparation and then doesn’t recur until the next cycle.
The problem with one-time training is that it decays. Employees who completed phishing awareness training eighteen months ago have largely reverted to their previous behaviors. Policies that were explained at onboarding aren’t well remembered by the second anniversary of someone’s hire date. And the threat landscape changes — the social engineering techniques that were current when training was delivered may look very different from the techniques being used against the organization today.
A continuous training model doesn’t require elaborate new content every quarter. It requires regularity — brief, relevant reminders that keep security practices front of mind, supplemented by annual refreshers that cover the full policy landscape. Phishing simulation programs, which test employee behavior rather than just knowledge, are particularly effective at maintaining awareness between formal training events.
Role-specific training matters here too. The engineer who handles technical data files faces different CUI risks than the contracts administrator who manages award documentation. Generic security awareness training covers the basics, but personnel with elevated access or unusual CUI exposure benefit from training that reflects their specific responsibilities and risks.
How to Integrate Compliance Into Change Management
One of the most common sources of control drift in defense contractor environments is unmanaged change. A new server gets added to the network. A software tool gets deployed without going through formal approval. A vendor relationship changes in scope without triggering a review of the access controls and contracts that govern it. Each of these changes can silently move the organization out of compliance without anyone realizing it until an assessor points it out.
The fix isn’t to slow down change — it’s to make compliance review part of the change management process. Every significant change to the CUI environment should go through a checklist that asks: does this change affect the assessment boundary? Does it introduce a new system that needs to be added to the SSP? Does it create a new data flow that changes how CUI moves through the environment? Does it require updating any access controls, configurations, or policies?
This is straightforward to implement in organizations that already have a formal change management process. It’s harder in organizations where change management is informal or inconsistently followed — which describes a significant portion of small and mid-sized defense contractors. If your organization is in that category, formalizing change management and wiring compliance review into it is one of the highest-leverage investments you can make in your continuous compliance program.
The CMMC model documentation addresses configuration management extensively under the CM practice domain, and assessors pay close attention to whether documented change management processes actually reflect how the organization operates, not just how it wishes it operated.
Metrics and Reporting: Giving Leadership Meaningful Visibility
A compliance program that leadership can’t see is a compliance program that won’t get funded. One of the structural advantages of a continuous model over a sprint model is that it produces ongoing metrics — data points that tell the story of compliance posture over time rather than just at assessment moments.
Meaningful CMMC compliance metrics for leadership typically include the current count of open POA&M items and their aging, the percentage of required controls with documented evidence versus those still in remediation, vulnerability scan results and remediation SLA adherence, training completion rates across the relevant employee population, and incident counts with resolution timelines.
None of these are complicated to produce if the underlying program is functioning. If they’re hard to produce, that difficulty is itself a signal — it means the program isn’t running continuously enough to generate the data naturally.
A vCIO who understands both the technical requirements and the business context can translate these metrics into leadership language — turning a list of open control gaps into a risk-adjusted conversation about resource allocation and strategic priorities. That translation is often what it takes to sustain executive support for compliance investment between assessment cycles.
Connecting Continuous Compliance to Business Continuity
There’s a dimension of continuous CMMC compliance that doesn’t always get framed this way but should: it’s also your best business continuity investment. The organizations that recover fastest from ransomware, recover fastest from CUI spillage incidents, and avoid the contract suspension that follows a confirmed breach are the ones running mature, continuous security programs — not the ones who were compliant on the day of their assessment and then let things drift.
CISA’s guidance on cyber resilience consistently emphasizes that resilience comes from operational continuity of security practices, not from documentation of them. Incident response plans that get practiced through tabletop exercises function differently during a real incident than plans that were written and filed. Backup systems that get tested quarterly restore predictably when recovery is needed. Monitoring that runs continuously detects incidents faster than monitoring that gets reviewed when someone remembers to check.
For defense contractors, the business continuity stakes are higher than in most commercial sectors. A cyber incident that results in contract suspension doesn’t just affect the current award — it affects the organization’s standing across the defense industrial base. A confirmed breach affecting CUI can trigger DFARS 252.204-7012 reporting obligations and attracts DoD scrutiny that extends well beyond the contract where the incident occurred.
Manufacturing and engineering organizations — which often carry significant operational technology alongside their IT environments — face particular continuity risks when security programs are treated as periodic rather than continuous. Our resources for manufacturing and engineering organizations reflect how continuous security and compliance practices apply in those operational environments.
The POA&M as a Living Document, Not a Pre-Assessment Formality
The Plan of Action and Milestones — the POA&M — is required under CMMC to document known gaps in control implementation and the timeline for addressing them. In a sprint model, the POA&M gets created under pressure before an assessment, lists every known gap, and then gets quietly shelved after the assessment is complete.
In a continuous model, the POA&M is a living document that’s reviewed regularly, updated as gaps are remediated, and populated with new items as internal audits surface them. It’s both a planning tool and an accountability mechanism — the record of what the organization knows about its own gaps and what it’s committed to doing about them.
Assessors look at the POA&M differently than many contractors expect. A POA&M with a history of items opened and closed on schedule signals an organization that’s managing compliance actively. A POA&M that was clearly created last month and has no history signals an organization that was caught unprepared. The document itself tells a story, and that story matters.
Keeping the POA&M current requires integrating it with your internal audit outputs, your vulnerability management process, and your change management workflow. When a new gap is found through any of these channels, it goes into the POA&M with an owner and a target date. When it’s remediated, evidence gets attached and the item gets closed. That cycle, running continuously, is what a mature program looks like.
Scoping, Vendors, and Organizational Change: Keeping the Program Current
Continuous compliance isn’t just about maintaining existing controls. It’s also about recognizing when the underlying environment has changed in ways that require the program itself to be updated. New vendors entering the CUI environment, changes in the assessment boundary due to new contracts or new technology deployments, organizational changes that affect who handles CUI — all of these require the compliance program to adapt, not just continue on autopilot.
Our piece on how to scope your CMMC environment correctly covers the foundational scoping decisions in detail, and the same discipline that produces a good initial scope needs to be applied every time the environment changes materially. Similarly, significant organizational events like acquisitions or rapid growth require compliance programs to be actively refit, as covered in our article on how mergers, acquisitions, and business expansion impact CMMC requirements.
A compliance partner who’s embedded in your environment on an ongoing basis — rather than engaged episodically for assessment prep — catches these changes as they happen and helps the program adapt in real time rather than after the fact. That proactive posture is the operational definition of continuous compliance.
Conclusion: Compliance That Works Every Day, Not Just on Assessment Day
The defense contractors that handle CMMC most effectively aren’t the ones with the most elaborate compliance documentation. They’re the ones whose compliance program is indistinguishable from how they run their security operations every day. The controls are functioning. The logs are being reviewed. The training happened last month, not eighteen months ago. The POA&M has a history. The SSP was updated when the last server was added.
That kind of program doesn’t require more total investment than the sprint model — it requires investment spread differently, embedded in operations rather than concentrated in pre-assessment surges. The payoff is assessments that confirm what you already know rather than uncovering what you’ve been avoiding, and a security posture that actually reflects the effort you’ve put into building it.
