DoD Clarifies CMMC Applicability for Paper only CUI: What Contractors Need to Know 

Earlier this month, the U.S. Department of Defense updated its Cybersecurity Maturity Model Certification (CMMC) Frequently Asked Questions (FAQ) to clarify the applicability of CMMC assessments when an organization handles Controlled Unclassified Information (CUI) in paper/hardcopy form only. This paper examines the substance of that clarification, its practical implications for defense contractors, and Atlantic Digital’s interpretation of the guidance in light of ongoing industry debate. 

Executive Summary

The Department of Defense recently clarified that organizations handling Controlled Unclassified Information (CUI) exclusively in hardcopy form are not required to undergo a CMMC assessment, provided the CUI is never processed, stored, or transmitted on a contractor-owned information system. This clarification affects assessment applicability, not safeguarding obligations. Contractors should review contract language carefully and approach “paper-only” scenarios with caution, as routine business practices often introduce digital CUI exposure.

What the DoD CMMC FAQ Says About Hard Copy CUI

The authoritative DoD CMMC FAQ (Version 4) explicitly includes the following question and answer, which is reproduced verbatim: 

"CQ10: Are CMMC assessments required for organizations that only handle hardcopy CUI?"

"CA10: No. Organizations that only handle hardcopy CUI should not be required to complete a CMMC Assessment. CMMC assessment requirements address cybersecurity related risk to CUI and apply only when the CUI is processed, stored, or transmitted on a contractor owned information technology system. Nonetheless, contractors are required to protect the hardcopy CUI. Per DoDI 5200.48, paragraph 1.1(b), any contractor or subcontractor that receives CUI is required to safeguard that information with Government training and safeguarding requirements.  

Additionally, if a contractor who was only provided hardcopy CUI plans to place the hardcopy CUI on an information technology system (e.g., scanned, entered, photographed, uploaded, printed, emailed), then that information technology system is subject to the applicable CMMC assessment requirements prior to the CUI being placed on the system.  

For organizations that handle paper CUI in addition to processing, storing, or transmitting CUI in a contractor owned information technology system, the necessary CMMC assessment will address both the paper CUI and the digital CUI, in accordance with the applicable NIST SP 800171 security requirements..." (Defense CIO) 

While the FAQ states that CMMC assessments will address both paper and digital CUI when an information system is in scope, this does not mean that hardcopy CUI is independently assessed outside the context of a contractor-owned information system. Rather, applicable NIST SP 800-171 controls (such as Physical Protection and Media Protection) are evaluated as they relate to safeguarding CUI within the assessed system boundary, while hardcopy-only CUI safeguarding requirements continue to be governed primarily by DoDI 5200.48 and contractual obligations. 

In summary, the FAQ clarifies that CMMC assessment requirements are tied to cybersecurity risk on contractor-owned IT systems. If CUI never touches such a system, a formal CMMC assessment is not required. However, this does not eliminate the safeguarding obligation: contractors handling only paper CUI remain responsible for complying with applicable physical protection and training requirements.

Business Processes Implications

For many defense contractors, particularly those that do not handle CUI at all, the FAQ has limited practical impact, because the FAQ addresses assessment applicability, not contract scoping. In such cases, DFARS clause 252.204-7012 and the associated NIST SP 800-171 requirements generally do not apply because Covered Defense Information (including CUI) is neither processed, stored, nor transmitted on the contractor’s information systems. DFARS 252.204-7012 requires contractors to provide adequate security only when covered defense information resides on or transits through a contractor-owned information system or network (DFARS).  

NIST SP 800-171 establishes security requirements specifically for the protection of CUI when it is processed, stored, or transmitted by nonfederal information systems operated by organizations. While organizations may have separate obligations to safeguard CUI in physical form under other authorities, such as DoDI 5200.48, NIST SP 800-171 does not function as a comprehensive safeguarding standard for paper-only CUI absent an information system context (NIST).  

Consequently, organizations that neither receive CUI nor process covered defense information on their systems may fall outside the scope of these cybersecurity requirements.  Applicability ultimately depends on contract language and the scope defined by the contracting officer, not solely on operational practices (Acquisition). 

For contractors that receive CUI exclusively in hardcopy form and do not process, store, or transmit that CUI on any contractor-owned information technology system, the FAQ indicates that a CMMC assessment is not required. This clarification does not create a new self-attestation pathway, nor does it negate obligations imposed DFARS clauses such as 252.204-7019 or 252.204-7020 when those clauses are included in a contract or flowdown. Whether self-assessment or certification is required remains dependent on solicitation language, contract requirements, and prime contractor flowdowns. (Defense CIO).

Risk and Practicality: Atlantic Digital’s Perspective

While the FAQ may appear to reduce assessment burden in narrowly defined scenarios, Atlantic Digital advises contractors to approach this guidance cautiously. 

The DoD’s clarification should not be interpreted as a determination that paper CUI is inherently low risk. Physical compromise, including theft, loss, or unauthorized access to printed technical data, remains a documented and credible threat vector. The FAQ reflects a scoping decision about assessment applicability, not a reduction in safeguarding expectations. 

At the same time, the DoD appears to be balancing mission risk against practical constraints within the Defense Industrial Base (DIB), particularly for very small or specialized organizations. By limiting third-party assessment requirements to scenarios involving contractor-owned IT systems, the DoD is attempting to reduce compliance friction where cyber risk exposure is comparatively limited. 

This balance between defense-in-depth principles and practical scalability is at the heart of the current industry debate. Contractors should not assume that “paper-only” CUI handling constitutes a safe harbor, as contract terms, prime contractor requirements, and routine business practices frequently introduce digital CUI exposure.

Atlantic Digital Guidance to Contractors

Atlantic Digital recommends that organizations: 

The DoD CMMC FAQ does not modify DFARS clauses, override solicitation requirements, redefine CMMC levels, or create new compliance pathways. It is interpretive guidance intended to clarify assessment applicability, not a binding regulatory change.

Conclusion

The DoD’s statement that a third-party CMMC assessment is not required for organizations handling only hardcopy CUI must be read with nuance. Assessment requirements are tied to cybersecurity risk on contractor-owned information technology systems. Hardcopy CUI remains subject to safeguarding obligations under DoDI 5200.48 and any applicable DFARS or NIST requirements when contractually required. Contractors should verify contract language and prime expectations carefully, recognizing that the FAQ provides clarification, not exemption, from security responsibilities. When uncertainty exists, deliberate scoping and early validation are far less costly than remediation later.

Updated 2025 Cost Framework for CMMC Level 2 Compliance: Integrating DoD, Industry, and Practitioner Data

This paper builds upon prior Atlantic Digital (ADI) research examining the financial and operational realities of achieving Cybersecurity Maturity Model Certification (CMMC) Level 2 compliance across the Defense Industrial Base (DIB). ADI’s 2024 “Feasibility of SMBs in the DIB” analysis (ADI, 2024a), explored the economic viability and strategic barriers for small and medium-sized businesses, while another paper (ADI, 2024b) established initial cost models and baseline implementation estimates.

This 2025 update advances that work by integrating newer Department of Defense (DoD) data with independently verified industry benchmarks, including insights from cybersecurity strategist Linda Rust (Rust, 2025) and practitioner commentary. Together, these sources produce an evidence-based view of CMMC Level 2 compliance costs, grounded in official estimates, validated analyses, and practitioner experience.

While cost modeling remains an important objective, the evolving conversation within the DIB has shifted focus from compliance as a technical obligation, to CMMC as a driver of organizational transformation. In line with ADI’s own long-standing posture (ADI, 2024c, ADI, 2024a), defense contractors and industry leaders recognize that CMMC readiness is not a one-time event but an ongoing business discipline that demands executive ownership, sustainable governance, and integrated risk management. In this context, cybersecurity compliance is inseparable from broader strategic and financial planning, shaping how defense suppliers structure their operations, allocate resources, and demonstrate long-term resilience.

Baseline Findings from ADI’s 2024 Analyses

The initial ADI analyses offered an early view of the practical cost burden facing small and medium-sized defense contractors pursuing CMMC Level 2 compliance. Both ADI reports argued that government estimates understated the financial burden for small businesses, focusing on structural and scale disadvantages (ADI, 2024a), and ADI, 2024b further highlighting that recurring internal labor and process maintenance are material components of lifecycle cost. Drawing on DoD data, ADI noted that the projected cost for the Level 2 assessment/affirmation component is approximately $104,670 for a small entity. This figure represents the baseline certification cost, excluding the recurring operational and labor expenses that ADI and others identify as the largest lifecycle contributors (ADI, 2024a; ADI, 2024b). Both papers positioned this baseline as an entry point, not a complete three-year total, indicating that human capital and governance activities are the dominant and most variable cost drivers. Subsequent analyses, including those by Rust (Rust, 2025) and other industry practitioners reinforce this conclusion, confirming that sustained labor, documentation, and process sustainment ultimately define the true economic scope of CMMC Level 2 compliance.

Official DoD Estimates

In January 2025, the Department of Defense published in the draft FAR CUI Rule (2024-30437) a high-level estimate of regulatory familiarization costs for achieving and maintaining CMMC Level 2 compliance. Unlike contractor-derived models that reflect field conditions, the DoD guidelines are designed to provide a benchmark for regulatory and budgeting purposes. In conjunction with the baseline costs described above, these guidelines can be interpreted as comprising three major cost components: one-time implementation—the initial “lift;” recurring operational costs; and third-party assessment costs, as summarized by Rust (Rust, 2025; DoD FAR CUI Rule, 2025; DoD, 2023).

According to the DoD data, the three-year cost for a representative small business is estimated to be approximately $487,970, consisting of $175,700 in initial implementation (labor ~$148,200 + hardware/software ~$27,500); $103,800 in recurring annual costs (labor ~$98,800 + hardware/software ~$5,000), and roughly $104,670 in total assessment costs (DoD FAR CUI Rule, 2025; DoD, 2023). These figures are summarized and discussed by industry analysts, including Rust (Rust, 2025), as the most comprehensive official baseline available.

Taken together, the DoD’s three-year projection implies an average annualized compliance burden of roughly $160,000 per year for a small business, yet industry reports consistently show that real-world costs often exceed this benchmark. Actual expenditures vary widely based on system scope, data complexity, and the maturity of internal controls. In practice, small and mid-sized contractors frequently report higher recurring labor and sustainment costs than the DoD model anticipates, a gap that becomes particularly evident when compared with practitioner-validated data.

In addition, it is important to note that the DoD assumes that defense contractors are already operating in conformance with DFARS and NIST requirements, and therefore treats CMMC certification as a marginal rather than initial compliance effort. In practice, however, many small businesses are still closing foundational gaps, making actual expenditures substantially higher than government projections.

Industry Dialogue and Validation

Practitioner dialogue led by industry expert Linda Rust offers an essential bottom-up validation of how CMMC compliance costs materialize in practice. Her 2025 LinkedIn series presents verified cost benchmarks across company sizes, confirming that CMMC Level 2 compliance can carry a six- to seven-figure price tag when broader programmatic labor, tooling, and sustainment are included (Rust, 2025).

Rust’s posts and the ensuing professional discussion revealed broad consensus that official DoD estimates understate the true scope of effort. While direct C3PAO assessments may range between $50,000 and $75,000 for well-prepared organizations, practitioners emphasized that the majority of expenditures occur earlier, through readiness activities, documentation, and recurring labor required to maintain compliance. These inputs can collectively situate one-time implementation costs between $120K to $250K, with recurring annual expenses of $50K to $100K, yielding multi-year program totals that can exceed $1 million when labor costs are considered (Rust, 2025).

The dialogue also broadened beyond cost precision to organizational behavior and strategic accountability. Industry participants emphasized that CMMC represents a long-term business transformation rather than a one-time audit event, requiring executive ownership, financial planning, and cultural alignment. They noted that poor scoping and inadequate data discovery can inflate costs by 20–30 percent, indicating that efficiency in compliance arises from disciplined governance, clear data boundaries, and proactive leadership engagement. Overall, these practitioner perspectives reinforce ADI’s and Rust’s shared conclusion that human labor and ongoing governance, rather than technology purchases or audit fees, are the largest and most variable components of CMMC Level 2 cost. This consensus reframes CMMC as an ongoing organizational investment in operational maturity and strategic resilience.

Practitioner and Community Corroboration

Practitioner reports from the defense contracting community provide an additional layer of validation grounded in lived experience. While not formally verified, these first-hand accounts help contextualize official and expert data by illustrating how cost variability plays out in practice.

A notable example appears in the Reddit thread titled “Costs for Certified Audit & Mock Audit,” where defense contractors share recent cost experiences. Across dozens of posts, contributors report mock audits ranging from $10K–$30K for smaller, well-prepared firms, with $30K–$50K as a common range for more extensive readiness support. Certified third-party assessments, in turn, often run $30K–$100K+ depending on organizational size, scope, and environmental complexity. Several participants noted that total readiness costs (consulting, remediation, and assessment fees) can approach or exceed $100K for small SaaS and complex IT environments. (r/CMMC, 2025).

These practitioner-level findings reinforce the pattern identified in both ADI and Rust’s analyses where audit fees alone rarely reflect the full economic footprint of compliance. The conclusion across government, professional, and community sources is that effective compliance depends as much on workforce capability and governance discipline as on tooling and assessment preparation.

Integrated Findings and Implications

The data reviewed here present a consistent picture of where CMMC Level 2 compliance costs truly reside. These findings synthesize data from official DoD estimates, ADI’s prior SMB feasibility models, Rust’s professional analysis, and practitioner reports from the CMMC community.

Across all sources, labor (both internal staff time and contracted expertise) emerges as the dominant cost driver, with underestimation of this component explaining much of the gap between official projections and real-world expenditures (ADI, 2024a, ADI, 2024b, Rust, 2025). Recurring subscription and tooling costs form a secondary but still significant component of total cost.

Beyond cost structure, governance maturity, scope definition, and early data mapping emerge as pivotal factors shaping financial outcomes. Industry experts repeatedly note that incomplete scoping or poorly mapped CUI can inflate total cost by as much as 30 percent during the discovery and readiness phases. In practice, this reinforces that cost efficiency is less a function of audit pricing and more a function of organizational readiness and disciplined preparation.

The professional dialogue also highlights that CMMC certification is the beginning, not the end, of a continuous resilience program. Effective programs integrate regular authorization reviews, workforce accountability, and visible executive sponsorship. For small and mid-sized contractors, early strategic planning, structured implementation, and continuous training are the most reliable levers for controlling lifecycle costs. Firms that operationalize CMMC as a business discipline rather than a periodic compliance exercise consistently achieve lower total costs while strengthening long-term security posture.

Atlantic Digital’s approach mirrors these findings. Rather than delivering one-size frameworks or isolated solutions, ADI helps contractors operationalize compliance as a business function. The methodology begins with establishing a readiness baseline and tailored scope definition, followed by cost modeling, control implementation guidance, documentation, training, and pre-assessment validation. The ultimate goal is sustainable compliance that executives can fund, manage, and defend, transforming CMMC from a regulatory obligation into a catalyst for stronger, more resilient operations.

As Linda Rust observed, the Defense Industrial Base will align to these requirements “one business leader at a time” (Rust, 2025). Partnering with advisors who translate the technical rigor of CMMC into practical business language, while understanding both regulatory detail and organizational culture, makes alignment far more achievable. Structured readiness planning and phased implementation allow organizations to mitigate financial and operational strain, even when six- to seven-figure expenditures are involved.

Looking ahead to full CMMC rollout between 2025 and 2028, integrated planning, strategic alignment, and disciplined execution will be essential for maintaining competitiveness, resilience, and long-term contract eligibility across the Defense Industrial Base.

Conclusion

Organizations that approach CMMC integrating cybersecurity into core operations and planning for continuous resilience, will better manage costs, protect critical information, and maintain long-term contract eligibility. Atlantic Digital supports contractors in achieving this configuration through readiness assessments, tailored scope definition, cost modeling, control implementation guidance, pre-assessment validation, and maintenance. By leveraging these services, companies can transform CMMC from a compliance obligation into an opportunity for sustained operational and security excellence.

The SA-24 Update: Critical Implications for Defense Industrial Base Compliance

The recent update to NIST SP 800-53 (Release 5.2.0) on August 27, 2025, introduced a significant new security control, SA-24 "Design for Cyber Resiliency," that warrants immediate attention from Defense Industrial Base (DiB) organizations (NIST 2025).

Rationale for SA-24 Introduction

The inclusion of SA-24 in NIST SP 800-53 Release 5.2.0 addresses the growing need for systems to be designed with inherent cyber resiliency. This control emphasizes the importance of anticipating, withstanding, recovering from, and adapting to adverse conditions, stresses, attacks, or compromises on systems that utilize or are enabled by cyber resources. This proactive approach aims to reduce mission, business, organizational, enterprise, or sector risk associated with cyber dependencies. The decision to introduce SA-24 was influenced by stakeholder feedback highlighting the necessity for a structured framework to embed cyber resiliency into system design processes (NIST 2025).

Strategic Significance for DiB Organizations

This update establishes a critical bridge between security compliance frameworks and systems security engineering, and, for DiB contractors, this development is particularly consequential for several reasons:

  1. Anticipatory Compliance Requirements: Although SA-24 is not currently included in NIST SP 800-171 Revision 3, it is anticipated that future revisions will incorporate this control. The alignment of SP 800-171 with SP 800-53 Revision 5, as seen in the recent updates, suggests a trend towards harmonizing security requirements across NIST publications. Organizations should proactively prepare for this integration by familiarizing themselves with the SA-24 control and considering its application in their current security practices (secureframe 2025; NIST 2024).
  1. CMMC Implications: Organizations pursuing Cybersecurity Maturity Model Certification should recognize this update as a potential indicator of future assessment criteria, particularly for higher maturity levels where resiliency requirements are emphasized.
  1. Competitive Differentiation: DiB contractors who proactively adopt cyber resiliency principles may secure advantageous positioning for future contract opportunities where robust security engineering is evaluated.

Technical Implementation Considerations

The SA-24 control establishes comprehensive requirements for cyber resiliency that align with strategic objectives outlined in SP 800-160 (NIST 2021):

To operationalize SA-24, organizations should map its elements to existing risk management frameworks and business continuity plans. For instance, the “organization-defined cyber resiliency goals” can be aligned with risk appetite statements in the risk register. Likewise, “cyber resiliency techniques” may be integrated into business continuity or disaster recovery strategies to ensure critical functions persist through and recover from adverse events. NIST SP 800-160 (Vol. 2) offers a technical foundation for selecting and applying techniques (e.g. redundancy, diversity, isolation, adaptability).

Procurement vehicles are increasingly reinforcing this convergence between compliance and resiliency. A prominent example is GSA’s OASIS+, a government-wide, multi-award IDIQ contract vehicle for acquiring complex professional services across domains (GSA. GSA). Under OASIS+, contractors responding to task orders may be required to fulfill J-3 “Cybersecurity/Supply Chain Risk Management (C-SCRM)” deliverables, which call for a documented cybersecurity program (mapped to NIST guidance), a C-SCRM plan, incident response capabilities, and business continuity/disaster recovery practices (GSA, GSA).

While OASIS+ is not itself a resiliency framework, its contractual deliverables illustrate how procurement requirements can drive adoption of resiliency-by-design principles like those in SA-24.


Implementing SA-24: Practical Examples:

Organizations can adopt various techniques to implement SA-24 effectively:

These techniques should be tailored to the organization's specific operational context and risk profile (GSA, NIST 2021).

Who Should Be Paying Attention

  1. Prime Defense Contractors: Organizations directly contracted with DoD handling CUI must closely monitor how this update will influence contractual requirements.
  2. System Security Engineering Teams: Technical specialists responsible for architecture design and security implementation need to integrate these resiliency principles into development lifecycles.
  3. Compliance Officers: Professionals tasked with maintaining regulatory adherence should begin evaluating how SA-24 principles align with existing control implementations.
  4. Risk Management Leadership: Executives responsible for enterprise risk governance must consider how cyber resiliency objectives will factor into broader business continuity planning.
  5. Supply Chain Security Managers: The emphasis on cyber resiliency complements the Supply Chain Risk Management (SR) family introduced in NIST SP 800-171 Rev. 3 (NIST 2024), suggesting an integrated approach to supply chain security and operational resilience.

This development underscores the evolving regulatory landscape's increasing focus on proactive, resilience-oriented security engineering rather than merely reactive compliance measures. Organizations that recognize this shift and adapt accordingly will be better positioned for both regulatory compliance and operational security effectiveness.

Conclusion

The introduction of SA-24 signifies a pivotal shift towards embedding cyber resiliency into the fabric of system design and operation. For DiB organizations, proactively adopting these principles not only ensures compliance with evolving standards but also fortifies the organization's ability to withstand and recover from cyber adversities. By aligning with SA-24, organizations demonstrate a commitment to safeguarding critical missions and maintaining trust with federal partners.

Demystifying GCC and GCC High Licensing for a CMMC Level 2 Assessment

Introduction

Picture this: You're sitting across from your CFO, armed with a Microsoft licensing quote that makes their coffee cup rattle against the saucer: $1,200 per user per year for G5 licenses. Meanwhile, your current Small Business Premium setup hums along nicely at $264 per user annually, delivering virtually the same user experience your team has grown to love. 

"So, where exactly can we cut corners?" 

That question echoes through boardrooms across America as government contractors grapple with CMMC Level 2 requirements. This complexity affects your IT budget, and it directly influences how assessors view your readiness when you undergo a CMMC Level 2 assessment. 

Assessment Success

Here's where the rubber meets the road in CMMC assessments. During your C3PAO evaluation, presenting an all-G5 licensing strategy is like showing up to a job interview in a perfectly tailored suit. You are more likely to get: 

Why? Because you've demonstrated earnest commitment to meeting NIST SP 800-171 requirements. C3PAOs know this configuration inside and out. It's their comfort zone. 

Step 1: Choose GCC vs GCC High

If your organization deals with International Traffic in Arms Regulations (ITAR) data or other export-controlled information, GCC High isn't optional. It's mandatory. But if you're working with standard Controlled Unclassified Information (CUI), the regular GCC environment might be your sweet spot. 

Once you know whether GCC High is required, the next challenge is choosing the right license model. 

Step 2: Pick Your License Model

Let's pull back the curtain on this licensing theater. The Microsoft 365 ecosystem for Government Community Cloud (GCC) presents three distinct paths, each with its own personality: 

The Premium Player: Microsoft 365 G5 (GCC and GCC High) 

GCC high and the G5 licensing is Microsoft compliance “promise” for the long-term partnership. Like Marriage, if you wanna keep it, put a ring on it, at $1,200. That premium price tag is paying for Microsoft’s special government teams to continue to develop technical controls against ever increasing threats. It provides: 

This is your "set it and forget it" solution, if budget constraints don't make you wince. 

The Strategic Alternative: Microsoft 365 E5 (no Teams) + Teams Enterprise (GCC Only) 

Here's where things get interesting. This configuration delivers identical security and compliance capabilities as G5 but often at a more palatable price point. It's like getting the same gourmet meal but choosing the lunch special over the dinner menu. This option does TODAY provide identical compliance, but it is not guaranteed like the G5 is, meaning organizations would require close monitoring of licensing updates. 

The Budget-Conscious Choice: Microsoft 365 Business Premium (GCC only) 

At a fraction of the cost, Business Premium provides essential desktop applications and basic security features. However, and this is crucial, it lacks the full compliance artillery needed for CUI handling. 

These licensing choices directly impact how assessors view your compliance readiness. 

Cost Scenarios

GCC High cost scenarios (20 users), MSRP (Aug 2025) 

Scenario Composition Annual total 
All G5 (GCC High) 20 × $1,120.80 $22,416.00 
3 G5 + 17 F3 + F5 Security (nonCUI) (3 × $1,120.80) + (17 × ($116.40 + $116.40)) $7,320.00 

Notes (GCC High): The F3 + F5 Security identities must not handle CUI. Enforce isolation with Conditional Access, Purview labels/DLP, and site/label scoping. F3 has no desktop apps, 2 GB OneDrive, and Kiosk/OWA mailbox unless you add Exchange Online Plan 1. 

GCC cost scenarios (20 users), MSRP (Aug 2025) 

Scenario Composition Annual total 
All G5 20 × $855.60 $17,112.00 
All E5 (no Teams) + Teams 20 × ($657 + $63) $14,400.00 
Hybrid (5 G5 + 15 BP) 5 × $855.60 + 15 × $264 $8,238.00 
Hybrid (5 E5 (no Teams) + Teams + 15 BP) 5 × $720 + 15 × $264 $7,560.00 
All BP + E5 Security (Need CMMC L2; currently no CUI) 20 × ($264 + $144) $8,160.00 

While these scenarios show clear cost differences, organizations must balance affordability against the compliance risks created when mixing license types. 

The Risk of Mixing Licenses

The moment you introduce a hybrid approach (some users on G5 licenses, others on "risk-managed" alternatives), your compliance complexity has elevated from arithmetic to calculus. Still very solvable, but with elevated acceptance of risks and sustainment processes. 

The assessor's scrutiny increases, since proving separation of environments becomes harder and often requires stronger documentation and compensating controls. This is due to: 

Imagine trying to prove a negative; that's essentially what you're asking your assessor to validate. 

Step 3: Build a Role-Based Licensing Strategy

Smart organizations develop a role-to-license matrix that serves as their North Star: 

The golden rule: Isolate CUI to your premium-licensed users. This creates clear boundaries that assessors can validate, and auditors can trace. 

Think of it as creating digital neighborhoods: your CUI community lives in the gated area with all the premium security features, while your general business operations happen in the standard residential zone. 

Here's the million-dollar question: Can you have your cake and eat it too? 

The pragmatic approach: 

  1. Start with role analysis rather than license analysis 
  1. Map CUI touchpoints across your organization 
  1. Right-size your premium licensing to actual CUI handlers 
  1. Document everything for assessment transparency 

Once the role-to-license matrix is established, the next challenge is ensuring this model can withstand assessor review and adapt to Microsoft’s evolving licensing changes. 

Implementation and Future-Proofing

Licensing isn’t a one-time purchase; it’s a living compliance program. To stay ahead of evolving CMMC expectations and Microsoft changes, organizations should implement clear governance and a forward-looking review process. 

Documentation That Demonstrates Control 

Assessors rely heavily on documentation, not just tools, to determine whether your controls are effective and sustainable. They will want to see: 

Remember, assessments aren't just about technical compliance, they're about demonstrating control maturity. An organization that can clearly articulate its licensing strategy, backed by solid documentation and consistent implementation, inspires assessor confidence. 

Future-Proofing Your Strategy 

The licensing landscape continues evolving. Microsoft regularly adjusts add-on eligibility and feature bundling.  

Build flexibility into your approach: 

Action Summary 

Conclusion

If you pursue CMMC Level 2 as a list of checkboxes and attempt to “save money” on licensing, you could end up with much higher costs down the road. 

CMMC Level 2 compliance should be part of your long-term business strategy. It's about building a sustainable security posture that protects your organization and your customers' sensitive information. 

Yes, G5 licensing represents a significant investment. But does the savings in licensing today justify the limitations you might face with ITAR, the extra sustainment costs in a complicated Hybrid licensing model, and the extra costs in the assessments? 
 
My advice: 
Different organizations will weigh these trade-offs differently. For example, as your compliance consultant, I will only recommend G5’s for all users within the information system because the elevated risks of a Hybrid approach require a full-time on-staff person to assume that liability. 

And as an IT director of a SMB with zero actual CUI in my information system, I am willing to protect by policy only and accept the liability of going with Small Business Premium licensing with the Security add-on. 

Remember: The goal isn't to find the cheapest option, but to find the most cost-effective path to compliance that protects your business, satisfies your contracts, and positions you for future growth. 

Because at the end of the day, the most expensive license is the one that doesn't protect you when it matters most. 

Ready to demystify your GCC licensing strategy? Atlantic Digital’s compliance experts have guided multiple contractors through this exact challenge. Contact us today for a personalized assessment that balances your budget constraints with your compliance requirements. 

Don't let licensing confusion derail your CMMC Level 2 journey. Get clarity, get compliant, get competitive.

DOM-based Extension Clickjacking: The Silent Threat to Your Password Manager

In the world of cybersecurity, sometimes the most dangerous threats are the ones hiding in plain sight, or rather, the ones hiding behind what you can’t see.

Introduction

Password managers have become the digital equivalent of Fort Knox for many of us (trusted guardians of our most sensitive information in an increasingly complex online world). We’ve been told repeatedly by security experts: use unique, complex passwords for every account and store them in a password manager. But what happens when the very tools designed to protect us become vectors for attack?

Czech security researcher Marek Tóth recently uncovered a sophisticated vulnerability affecting popular password manager browser extensions that could make your digital fortress about as secure as a sandcastle at high tide. This newly identified attack vector, dubbed “DOM-based extension clickjacking,” has sent shockwaves through the cybersecurity community, affecting extensions with a combined user base exceeding 40 million installations (Tóth).

The Art of Digital Sleight of Hand

Imagine you’re browsing a website and encounter a seemingly innocent cookie consent banner. You click “Accept” to dismiss it and continue browsing. Simple, right? Not quite. Through DOM-based extension clickjacking, that single click might have just handed over your credit card details, including security codes, to an attacker without you noticing a thing.

But how exactly does this digital sleight of hand work? DOM-based extension clickjacking represents an evolution of traditional clickjacking attacks, specifically targeting browser extensions that inject interactive elements into a webpage’s Document Object Model (DOM).

The attack exploits a fundamental aspect of how password manager extensions interact with web pages:

What makes this attack particularly concerning is its minimal interaction requirements. In many demonstrated scenarios, a single user click is sufficient to extract sensitive information.

Technical Mechanics

The DOM-based extension clickjacking vulnerability exploits several technical approaches:

As Tóth explains, “The principle is that a browser extension injects elements into the DOM, which an attacker can then make invisible using JavaScript” (Tóth).

The Damage Potential

The severity of this vulnerability varies depending on context, but several concerning attack scenarios have been demonstrated:

On Malicious Websites

On Legitimate but Compromised Websites

Particularly concerning is how the attack can exploit the subdomain autofill behavior of password managers. If a user has credentials stored for a domain like accounts.google.com, an attacker only needs to find an XSS vulnerability on any subdomain (e.g., test.dev.sandbox.cloud.google.com) to potentially steal those credentials.

Affected Password Managers

Tóth’s research presented at DEF CON 33 identified vulnerabilities in several password managers at the time of disclosure. The versions tested are listed below, though patch status has since varied. Users should consult vendor advisories for the latest updates:

The response from vendors has varied significantly. Some have quickly addressed the issue with comprehensive fixes, while others have taken a more measured approach or initially classified the issue as “informative” rather than a direct vulnerability in their products.

Jacob DePriest, CISO at 1Password, has noted that “the underlying issue lies in the way browsers render webpages” and that there’s “no comprehensive technical fix that browser extensions can deliver on their own” (Security Week). This stance highlights the fundamental tension between usability and security in password manager design.

Mitigation Strategies for Users

While awaiting comprehensive fixes from vendors, users can take several proactive steps to protect themselves:

The Balancing Act

The discovery of DOM-based extension clickjacking vulnerabilities highlights a fundamental challenge in security design: the balance between usability and protection. While separate popup windows for autofill would provide stronger security against clickjacking, they would also introduce significant friction to the user experience, potentially driving users toward less secure practices out of convenience.

As Alex Cox, Director of Threat Intelligence at LastPass, notes, this research “highlights a broader challenge facing all password managers: striking the right balance between user experience and convenience, while also addressing evolving threat models” (Daily Security Review).

Conclusion

The DOM-based extension clickjacking vulnerability serves as a stark reminder that even security tools require vigilant oversight and continuous improvement. As password managers have become increasingly central to cybersecurity strategies, they have also become more attractive targets for sophisticated attacks.

Users should remain alert to potential risks while maintaining perspective; password managers still provide significant security benefits compared to alternative approaches like password reuse or weak memorized credentials. The appropriate response is not abandonment of these tools, but rather informed usage combined with additional security layers.

For the password management industry, this discovery highlights the need for continued innovation in secure design patterns for browser extensions. Future approaches may include greater isolation between extension interfaces and webpage content, improved verification of user intent before sensitive operations, and more robust detection of potential manipulation attempts.

As vendors continue to release updates addressing these vulnerabilities, users should prioritize keeping their software current and implementing available security options. By combining technical protections with informed usage practices, the risks associated with DOM-based extension clickjacking can be significantly reduced while preserving the substantial security benefits that password managers provide.

Navigating the Latest DoD Memo on CMMC Certification Requirements with Atlantic Digital

Introduction

The Department of Defense (DoD) continually updates its cybersecurity protocols to safeguard sensitive information within the Defense Industrial Base (DIB). The latest memorandum, "Implementing the Cybersecurity Maturity Model Certification (CMMC) Program" (DoD), introduces significant changes to the Cybersecurity Maturity Model Certification (CMMC) requirements, directly impacting contractors and service providers. This paper examines these updates, addresses critical compliance challenges, and outlines how Atlantic Digital (ADI) helps clients achieve compliance.

Understanding the Latest DoD Memo on CMMC

The recent DoD memorandum formalizes the CMMC framework by confirming a phased implementation and clarifying the conditions under which different levels of certification are required. It also provides new guidance on waivers and subcontractor compliance. 

Key updates include: 

Phased Implementation Process 

The DoD memo confirms that CMMC implementation will begin once the final Title 48 CFR rule is published. Implementation will proceed as follows: 

CMMC Level Assessments 

CMMC builds upon NIST SP 800-171 self-assessments already obligatory under DFARS 252.204-7019, and organizations must continue conducting these assessments as required. Additionally, the CMMC Program requires pre-award assessments of covered contractor information systems against prescribed cybersecurity standards for safeguarding Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). 

Assessment Breakdown: 

Flow-Down Requirements for Subcontractors  

The memo warns that CMMC Level 3 requirements should not be unnecessarily flowed down to all subcontractors, as this could impose undue financial and administrative burdens. Program Managers must ensure only essential subcontractors handling mission-critical CUI are subject to Level 3 requirements.  

New CMMC Waiver Process 

The memo establishes a waiver process, allowing SAE/CAE officials to waive CMMC certification under specific conditions. Waivers do not remove cybersecurity compliance obligations but offer flexibility in cases where certification requirements could limit competition. 

Waiver Guidelines: 

Identified Compliance Challenges

While the DoD memo provides clarity on CMMC requirements, additional challenges arise when managing information such as Export-Controlled Information (EXPT), which is regulated under separate frameworks like the International Traffic in Arms Regulations (ITAR) and the Export Administration Regulations (EAR). Unlike Controlled Technical Information (CTI), which directly triggers CMMC Level 2 requirements under DoD contracts, EXPT is a broader category of Controlled Unclassified Information (CUI) that applies across multiple federal agencies, including the Departments of Commerce and State. As a result, contractors handling EXPT may face cybersecurity requirements that extend beyond DoD mandates and into multi-agency oversight (DoD, Export Solutions). 

Key Challenges 

In this sense, understanding the interplay between CMMC, DFARS, and export control regulations is critical for organizations handling sensitive government data. The presence of EXPT can introduce additional layers of compliance, even when CMMC is not explicitly required by DoD. Contractors must evaluate regulatory obligations beyond DoD contracts, ensuring that cybersecurity measures align with both defense and non-defense federal agency requirements.
