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

Posted on September 25, 2025 by Jimmy Lamon CCIE #46581

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:

A lower assessment quote

Potential for remote assessment options

A faster assessment timeline

More assessor confidence

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.

Require GCC High: Mandatory if your contracts include Export-Control specifications (ITAR/EAR).

Prefer GCC High: Often chosen proactively because ITAR requirements can appear unpredictably, and it positions you for future contracts.

Need cost-effective solution: GCC provides better affordability with expanded licensing selections

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:

Comprehensive security stack with Entra ID P2

Defender for Endpoint P2 protection

Full Purview E5 capabilities for advanced compliance

Advanced Audit and eDiscovery Premium features

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:

In-scope email boxes sitting alongside risk-managed email boxes

Policy-based separation without ironclad technical controls

No eDiscovery proof that CUI hasn’t migrated to risk-managed environments

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:

CUI Handlers & Compliance-Critical Roles → G5 or E5 (no Teams) + Teams Enterprise

Support Staff & Non-CUI Roles → Business Premium (GCC)

Hybrid Roles → Case-by-case evaluation with clear documentation

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:

Start with role analysis rather than license analysis

Map CUI touchpoints across your organization

Right-size your premium licensing to actual CUI handlers

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:

Clear licensing rationale tied to job functions

CUI flow diagrams showing data boundaries

Change management procedures for role transitions

Regular access reviews and cleanup processes

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:

Maintain licensing inventory with regular reviews

Monitor Microsoft roadmap announcements

Establish change management protocols

Budget for compliance evolution

Action Summary

G5 = Safest, fastest assessments

GCC High = Mandatory if ITAR/EAR data

Hybrid = Lower cost, higher risk, requires strong controls

Document licensing decisions tied to roles

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.

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

Posted on March 11, 2025 by Mabel Sabogal, PhD

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:

CMMC certification requirements will be introduced incrementally upon publication of the final DFARS rule, 2019-D041. Contractors must prepare for increasing compliance obligations over the next two years as Level 1, Level 2, and Level 3 requirements take effect.

The memo reiterates that CMMC Level 3 requirements should not be unnecessarily imposed on subcontractors unless they handle mission-critical CUI. Program Managers are advised to take a risk-based approach when determining subcontractor obligations.

Service and Component Acquisition Executives (SAE/CAE) may waive CMMC certification requirements under certain conditions but must still ensure compliance with cybersecurity safeguards.

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:

Upon publication of the final DFARS rule, 2019-D041, CMMC Level 1 requirements will take effect for applicable contracts.

One year after DFARS publication, CMMC Level 2 assessments will be introduced as part of the phased implementation process.

Two years after DFARS publication, CMMC Level 3 certification assessments will be mandatory, when appropriate.

The DoD will update Instruction 8582.01 and provide additional guidance regarding the application of NIST SP 800-172 protections for Level 3 contractors.

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:

CMMC Level 1 requires an annual self-assessment against 17 basic cybersecurity practices, based on the Federal Acquisition Regulation (FAR) 52.204-21.

CMMC Level 2 requires adherence to NIST SP 800-171 requirements. Depending on the sensitivity of the Controlled Unclassified Information (CUI) handled, assessments may be either self-assessments or conducted by a Certified Third-Party Assessment Organization (C3PAO).

CMMC Level 3 requires a DoD-led assessment, incorporating NIST SP 800-172 enhanced security requirements.

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:

CMMC waivers may be granted on a case-by-case basis by SAE/CAE officials

All cybersecurity requirements remain in effect, regardless of whether a waiver is granted.

According to the memo, “There are no circumstances likely to warrant approval of requests to waive CMMC Level 1 requirements.”

The memo confirms that some “…CMMC Level 2 third-party assessment requirements may be waived under certain conditions,” but “there are no circumstances likely to warrant approval of requests to waive CMMC Level 2 self-assessment requirements.”

Waivers for Level 3 contractors will be highly limited due to their handling of mission-critical CUI.

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

Export Controlled (EXPT) information is classified as Controlled Unclassified Information (CUI) under the National Archives’ CUI Registry. This classification encompasses unclassified technical data, software, or other items subject to export restrictions under the International Traffic in Arms Regulations (ITAR) or Export Administration Regulations (EAR) (National Archives, DoD)

While EXPT itself is not categorized as Controlled Technical Information (CTI), there are instances where the same dataset may be classified as both EXPT and CTI (National Archives, National Archives). In such cases, contractors may be required to comply with multiple regulatory frameworks, including DFARS 252.204-7012 and export control laws.

The presence of EXPT in a Department of Defense (DoD) contract does not automatically trigger CMMC certification requirements. However, if a contract involves both EXPT and CTI, the contractor may be required to undergo a full CMMC Level 2 assessment due to the handling of CTI. Additionally, in cases where a non-DoD agency is involved, equivalent cybersecurity measures may be required even if the DoD does not impose them directly.

Since ITAR and EAR compliance imposes security requirements beyond those outlined in NIST SP 800-171, organizations must implement a dual compliance strategy. Contractors should assess regulatory obligations across all awarding agencies to ensure alignment with both DoD and export control cybersecurity requirements.

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.

The 32 CFR CMMC Final Rule: Implications, and Preparations for Defense Contractors

Posted on October 16, 2024 by Mabel Sabogal, PhD

Introduction

The cybersecurity landscape is undergoing rapid transformation, and the Department of Defense (DoD) is making substantial strides to safeguard sensitive information. On October 15, 2024, the 32 CFR Cybersecurity Maturity Model Certification (CMMC) Final Rule was published in the Federal Register, marking a pivotal development in defense cybersecurity (visit Atlantic Digital for a detailed timeline of these developments). This framework strengthens cybersecurity compliance across the Defense Industrial Base (DIB) by aligning with NIST standards and reinforcing the security posture of DoD contractors. Understanding the key changes and implications of this new rule is essential for defense contractors navigating the evolving landscape of cybersecurity regulations.

Key Changes and Requirements

The CMMC Final Rule introduces significant changes to the cybersecurity requirements for DoD contractors. It places the onus of compliance timing on contractors and subcontractors, requiring them to achieve the specified CMMC level before contract awards. This shift necessitates careful consideration of business objectives, and the resources required for certification.

Once fully implemented, the DoD will only accept assessments from authorized and accredited Certified Third-Party Assessment Organizations (C3PAOs) or certified CMMC Assessors (DoD CIO, Cyber AB). This ensures a standardized approach to cybersecurity evaluation across the DIB. The proposal introduces a tiered system for assessments based on the sensitivity of the information handled. Contractors dealing with Federal Contract Information (FCI) will be required to perform annual self-assessments, while those managing critical national security information will undergo CMMC Level 2 third-party assessments. The most critical defense programs will face government-led assessments. (Atlantic Digital)

Additionally, the rule introduces a CMMC assessment appeal process, allowing organizations to address disputes related to assessor errors or unethical conduct. However, ultimate liability in assessment disputes remains between the organization seeking certification and the C3PAO (DoDCIO). To maintain transparency and accountability, the DoD will have access to assessment results and final reports. Contractors’ self-assessment results will be stored in the Supplier Performance Risk System (SPRS), while CMMC certificates and third-party assessment data will be housed in the CMMC Enterprise Mission Assurance Support Services (eMASS) database (DoD CIO).

Impact on Small and Medium Businesses

The CMMC Final Rule has significant implications for small and medium businesses (SMBs) in the DIB. These organizations face unique challenges in achieving compliance with the new cybersecurity standards.

One of the primary hurdles is the correct identification and categorization of CUI and FCI. Many small businesses struggle with this task (DoD CIO). Additionally, the financial burden of implementing CMMC requirements presents a significant concern for these businesses. The costs associated with security controls, audit preparation, and the certification process can be substantial, placing a heavy strain on companies with limited budgets (Atlantic Digital). Furthermore, small businesses must also consider the operational, technical, legal, and scheduling implications of either achieving or failing to meet compliance standards, which can affect their ability to continue doing business with the DoD (Atlantic Digital). SMBs need to work proactively to address these challenges, to enhance cybersecurity resilience, and capitalize on growth opportunities in the defense sector.

Preparing for FY25 Implementation

As the Department of Defense (DoD) prepares for full CMMC implementation, contractors must take calculated measures to ensure compliance. The phased rollout plan, expected to begin in FY25, underscores the need for readiness, as the number of contracts requiring CMMC certification is projected to increase significantly. (ClearanceJobs, Atlantic Digital).

To prepare, organizations should first identify their required CMMC level based on the sensitivity of the information they handle. Conducting a thorough NIST 800-171 and CMMC gap analysis is crucial to assess the current cybersecurity posture. Companies must then develop comprehensive System Security Plans (SSPs) and Plans of Action & Milestones (POA&Ms) to address any identified gaps (Federal Register).

Partnering with a C3PAO is crucial for the certification process. However, to prevent conflicts of interest, C3PAOs are prohibited from offering consulting services before conducting their assessments. This is where Atlantic Digital (ADI) comes in. As a consultant, ADI provides expert guidance that simplifies the certification process, ensuring timely compliance and facilitating smooth access to government contracts.

Conclusion

The evolving cybersecurity landscape and the DoD’s push to enhance protection through the CMMC final rule represent a significant shift for defense contractors. The framework aims to strengthen the cybersecurity posture of organizations across the DIB by aligning with NIST standards and streamlining compliance requirements. With the phased implementation plan set to begin in FY25, it is crucial for contractors to proactively address the upcoming changes.

Understanding the intricacies of the proposed CMMC final rule is essential for organizations seeking to maintain and secure their defense contracts. The adjustments outlined in the Federal Register Final Rule emphasize the need for contractors to be vigilant, prepared, and aligned with new compliance requirements. By conducting thorough gap analyses, developing robust security plans, and engaging with experts at organizations such as ADI, contractors can better navigate the complexities of CMMC certification and ensure they meet the necessary standards.

As the defense sector prepares for these pivotal changes, staying informed and taking decisive action will be crucial for maintaining a competitive edge and safeguarding sensitive information. The CMMC Final Rule represents not only a regulatory shift but also an opportunity for organizations to enhance their cybersecurity resilience and align with industry best practices.

CMMC Timeline

Posted on October 16, 2024 by Mabel Sabogal, PhD

Introduction 

The Cybersecurity Maturity Model Certification (CMMC) serves as a vital framework established by the Department of Defense (DoD) to bolster cybersecurity within the Defense Industrial Base (DIB). As cybersecurity threats continue to evolve, the necessity for a comprehensive certification process has become increasingly urgent. The publication of the 32 CFR Cybersecurity Maturity Model Certification (CMMC) 2.0 Final Rule in the Federal Register on October 15, 2024, marks a pivotal development in the DoD’s mission to safeguard sensitive information. This framework is designed not only to enhance compliance among defense contractors but also to ensure the implementation of robust security measures essential for protecting Controlled Unclassified Information (CUI).

Understanding the nuances of the Federal Register is critical in this context, as it serves as the official journal of the U.S. government, detailing proposed and final rules along with other significant regulatory documents.

The Federal Register and Its Role in Rulemaking

The Federal Register plays a crucial role in the rulemaking process by providing transparency and enabling public feedback on proposed regulations. The publication of a proposed rule in the Federal Register follows a period of internal development and review, leading to a public comment period where stakeholders can express support, concerns, or suggestions for modifications. Although the timeline for finalizing a rule can vary, the publication of a proposed rule signifies the DoD’s intent to enforce new cybersecurity standards, making these requirements binding across the DIB. Once a rule is finalized, it is officially published in the Federal Register as a Final Rule, signaling that all public input has been considered, and the rule is ready to be implemented and enforced as law. (Federal Register).

Timeline for the CMMC Program 

Building on the foundation established by the Federal Register, understanding the evolution of the CMMC program leading to CMMC 2.0 is essential. It is important to note that the security requirements forming the basis of CMMC 2.0 Level 2, as outlined in NIST SP 800-171, have been mandatory for DoD contractors handling sensitive information since December 2017. This requirement followed the introduction of DFARS clause 252.204-7012, which addresses the safeguarding of Covered Defense Information and Cyber Incident Reporting in DoD solicitations and contracts. However, enforcement of these requirements initially relied on self-attestation, lacking an effective verification process.

Consequently, many contractors did not fully implement the necessary security controls, which limited the DoD’s ability to ensure compliance. In response to these challenges, the DoD initiated the CMMC program as a structured framework for verifying compliance with the DFARS requirements. This initiative established a system through which compliance is assessed by CMMC Third Party Assessment Organizations (C3PAOs), which are certified by the DoD (RiskInsight).

Some of the CMMC program key milestones are as follows: 

In 2019, the DoD announced the development of the Cybersecurity Maturity Model Certification (CMMC) as a crucial step to enhance the cybersecurity posture of the Defense Industrial Base (DIB) sector against evolving threats. This initiative was conceived by the Office of the Under Secretary of Defense for Acquisition and Sustainment (OUSD(A&S)) to transition from a self-attestation model of security to a structured certification process (Federal Register).

On September 9, 2020, the DoD published the 48 CFR CMMC interim rule to the DFARS in the Federal Register (DFARS Case 2019-D041 85 FR 48513), which implemented the DoD’s initial vision for the CMMC program (“CMMC 1.0”) (DoDCIO, Federal Register).  This rule integrated requirements from the DFARS clause DFARS 252.204-7012, mandating defense contractors to implement NIST SP 800-171 controls to safeguard Covered Defense Information (CDI—Unclassified information specifically connected to defense contracts, programs, or operations), and report cyber incidents within 72 hours (Summit7). Additionally, it extended these obligations to subcontractors throughout the supply chain, introducing clauses like 252.204-7020 and 252.204-7021 that govern compliance with CMMC requirements and assessment methodologies. This shift formalized the CMMC certification process and emphasized the importance of protecting Controlled Unclassified Information (CUI), which is sensitive information that, while not classified, could still pose a risk to national security or other critical interests if improperly disclosed.

CMMC 1.0 ensured that contractors handling CUI met a baseline cybersecurity standard and could respond quickly to cyber incidents. It required these contractors to obtain third-party CMMC certification through C3PAOs, marking a significant departure from the self-attestation approach under DFARS 252.204-7012.  The interim 48 CFR CMMC 1.0 rule became effective on November 30, 2020, marking the start of a phased rollout of CMMC requirements over five years (Federal Register, DoDCIO, CyberSheath, Acquisition.gov, LII / Legal Information Institute).

 In March 2021, the Department initiated an internal review of CMMC’s implementation, responding to approximately 750 public comments on the 48 CFR CMMC interim final rule. This review led to proposed updates, that would ensure the incorporation of the latest CMMC 2.0 requirements into the federal acquisition process. These updates were intended to provide clarity and enforce compliance, aligning cybersecurity requirements with the CMMC standards (Federal Register).

The DoD announced 32 CFR CMMC 2.0, on November 4, 2021. This revision aimed to simplify the certification structure to three levels and reduce the cost burden on small and medium-sized businesses (SMBs), while also aligning assessments with NIST standards and maintaining key protections outlined in DFARS 252.204-7012 (Summit7, DoDCIO, CyberSheath), The 32 CFR CMMC 2.0 Proposed Rule was subsequently published in the Federal Register on December 26, 2023 (DoD).

On June 27, 2024, the DoD submitted a draft of the 32 CFR CMMC 2.0 Final Rule to the Office of Information and Regulatory Affairs (OIRA), which is part of the standard rulemaking process, marking a key step toward the finalization of CMMC 2.0 (RiskInsight).

Additionally, on August 15, 2024, the DoD issued a Proposed Rule to amend the Defense Federal Acquisition Regulation Supplement (DFARS), incorporating the latest CMMC 2.0 requirements (Arnold & Porter, Atlantic Digital). This amendment updates the existing requirements of DFARS 252.204-7021, which outlines the cybersecurity certification levels that contractors must achieve to handle sensitive defense information. This rule builds directly upon the requirements established in DFARS 252.204-7012.  It also aligns with 32 CFR 117.8, which specifies reporting requirements for contractors working with classified information. Both 32 CFR 117.8 and the DFARS regulations emphasize the importance of reporting security incidents and any material changes that could affect defense contracts. (National Archives, DoD). Following its publication in the Federal Register, the Proposed Rule initiated a public comment period. Once this period concludes and revisions are implemented based on stakeholder feedback, the rule is expected to be finalized in early 2025, becoming enforceable and requiring all contractors to comply with the updated CMMC 2.0 standards to be eligible for DoD contracts. This proposed rule will also serve as an update to the 48 CFR, which governs the entire federal acquisition process, ensuring consistent alignment with cybersecurity requirements.

Finally, the 32 CFR CMMC 2.0 Final Rule was published on October 15, 2024, and will become effective on December 16, 2024. This rule mandates that contractors must be certified under CMMC 2.0 before they can bid on or be awarded defense contracts; thereby, enforcing the CMMC 2.0 requirements across the DIB. The phased rollout will facilitate a gradual compliance process for contractors, ultimately strengthening cybersecurity across the entire defense supply chain.  The full impact of the Final Rule is expected to manifest in early 2025 (Arnold & Porter, ECURON).

In sum, the 48 CFR Final Rule, which includes the DFARS as a supplement to the Federal Acquisition Regulation, will enforce compliance through contractual obligations. In contrast, the 32 CFR Final Rule will outline the detailed cybersecurity practices contractors are required to adopt. This alignment between the DFARS and the 32 CFR Final Rule demonstrates the DoD’s concerted effort to integrate stringent cybersecurity controls and reporting protocols into defense contracts, ensuring that the entire defense supply chain is fortified against potential cybersecurity threats.

Conclusion

The timeline of the CMMC program reflects a critical evolution in the DoD’s approach to cybersecurity. The integration of the CMMC requirements into the federal acquisition process, as detailed in the Federal Register, underscores the importance of a structured, enforceable framework for protecting sensitive information. By mandating compliance and certification, the DoD is taking essential steps to enhance the cybersecurity posture of the Defense Industrial Base, ensuring that contractors are equipped to manage and mitigate potential threats effectively.

Feasibility of SMBs in the Defense Industrial Base

Posted on September 4, 2024 by Mabel Sabogal, PhD

Introduction

The feasibility of small to medium-sized businesses (SMBs) within the Defense Industrial Base (DIB) is largely dependent on their ability to achieve Cybersecurity Maturity Model Certification (CMMC) in 2025. This certification is essential for securing and renewing contracts with the Department of Defense (DoD), driven by the need to safeguard Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) from cybersecurity threats.

In 2025, many DoD contracts, especially those involving CUI, will mandate CMMC Level 2 certification. This requirement is part of a phased implementation strategy by the DoD, with full enforcement expected by fiscal year 2026. The DoD provided an estimate that about 80,598 entities will be affected by the CMMC Level 2 requirements. Of these, it is anticipated that around 95% (approximately 76,598 entities) will need to obtain certification from a Certified Third-Party Assessor Organization (C3PAO) due to the involvement of Controlled Unclassified Information (CUI) in their contracts, rather than relying on self-assessment alone (Venable LLP; The National Law Review; InterSec).

Achieving CMMC Level 2 involves meeting 320 assessment objectives outlined in NIST SP 800-171a, posing a substantial challenge for SMBs with limited cybersecurity resources. The DoD has estimated that the cost for small defense contractors to achieve this certification is around $104,670 (Prevail), covering third-party assessments and ongoing compliance efforts. However, real-world scenarios suggest that the actual costs may vary significantly (Atlantic Digital, Etactics). The transition to CMMC, announced in November 2021, has simplified the certification process by reducing the levels from five to three, thereby easing some administrative burdens on smaller businesses. Nonetheless, maintaining certification remains a challenge for SMBs. The high demand for certified assessors as the compliance deadline nears further emphasizes the need for early preparation.

While the path to CMMC Level 2 certification is demanding, it offers an opportunity for SMBs to strengthen their cybersecurity posture and secure a position in the defense contracting landscape. The ability of these businesses to navigate these requirements will be crucial for their continued participation in the DIB and the resilience of the broader defense supply chain. For SMBs unsure whether CMMC Level 2 is necessary, it is essential to check their contracts for DFARS Clause 252.204-7012, “Safeguarding Covered Defense Information and Cyber Incident Reporting.” This clause, enforced since 2016, mandates that contractors implement the security requirements specified in NIST SP 800-171 to protect Covered Defense Information (CDI) and report cyber incidents to the DoD. Achieving CMMC Level 2 ensures compliance with these rigorous standards, emphasizing foundational and advanced cybersecurity practices crucial for securing sensitive information and supporting national security.

Operational and Technical Feasibility

Compliance with CMMC Level 2 requires alignment with NIST SP 800-171 standards, which specify security requirements for nonfederal information systems, and are essential for protecting CUI (NIST). Organizations must assess whether their processes, workforce, and systems can support the demands of CMMC Level 2. The Center for Development of Security Excellence (CDSE) highlights the need for a well-prepared workforce and robust processes (CDSE). Similarly, the Cybersecurity and Infrastructure Security Agency (CISA) underscores that a comprehensive approach combining technological solutions with staff training is vital for CMMC Level 2 compliance (CISA); thus, SMBs need to establish the necessary cybersecurity infrastructure, invest in cybersecurity technologies, and workforce training and development to meet these standards.

Economic Feasibility

The economic feasibility of achieving CMMC Level 2 certification is a major concern for SMBs in the DIB. Government estimates for certification costs often underestimate the full scope of expenses. A thorough cost-benefit analysis must account for initial assessment costs and recurring expenses for maintaining compliance.

Initial Assessment Costs

According to the DoD, “a Level 2 certification assessment is projected to cost nearly $105,000 for small entities and approximately $118,000 for larger entities (including the triennial assessment and affirmation and two additional annual affirmations)” (in Defensescoop). However, real-world examples show significant variation in initial assessment costs, from $30,000 to $381,000 (Etactics). For a small organization requiring a basic 4-person, cloud-only setup, Atlantic Digital (ADI) has been quoted $30,000, whereas larger organizations face costs closer to $100,000. These figures cover assessments by a C3PAO but exclude costs for technology upgrades, staff training, and long-term compliance (Atlantic Digital).

Cost Considerations

Technology and Infrastructure Upgrades: Essential upgrades can be costly. For instance, engineering costs for CMMC Level 3, which builds on Level 2, range from $490,000 to $21.1 million (Farmhouse, Dewpoint). These figures, while for Level 3, highlight the substantial investments needed even at Level 2.

Staffing and Outsourcing: Hiring specialized staff or consultants is often necessary. External consultant costs can start at $60,000 annually, rising to $150,000 and beyond for comprehensive support (Atlantic Digital).

Operational Costs: Ongoing expenses include training programs and upgrades:

Operational Costs
KnowBe4 for training	$9,072/year
Endpoint upgrades	$1,000/user
DocuSign	$3,000/year
External Certificate Authority (ECA)	$500/user
Privileged User Training	$400 /Privileged User annually
Password Vault	$96/Privileged User annually

Migration and Implementation Costs: Medium-sized companies have spent over $1 million annually over three years for cloud migrations and an additional $240,000/year for consulting, staff augmentation and compliance maintenance (Atlantic Digital).

Additional Costs: SMBs with on-premises CUI handling may face extra costs for printing, upgrades, infrastructure improvements, and physical security (Atlantic Digital).

In short, the financial burden of achieving and maintaining CMMC Level 2 compliance can be significant for SMBs. While federal estimates provide a starting point, actual costs can be much higher. A comprehensive approach, including detailed cost estimations and leveraging cost-effective services, is essential for SMBs to navigate these economic challenges.

Atlantic Digital has published a blog post detailing the expenses associated with CMMC certification and discussing why the government often underestimates these costs.

Legal Feasibility

Adherence to DoD cybersecurity and data protection regulations is crucial to avoid legal and financial repercussions. The Defense Counterintelligence and Security Agency (DCSA) emphasizes that compliance is essential for continued participation in DoD contracting opportunities (DCSA, InterSec). Non-compliance could result in loss of contracts and financial penalties.

Schedule Feasibility

The 2025 deadline for CMMC Level 2 presents a significant challenge due to the limited number of Certified Third-Party Assessment Organizations (C3PAOs). As of July 2024, about 56 C3PAOs are available, each capable of handling 1 to 10 assessments per month, resulting in an estimated 504 to 5,040 assessments before the deadline. This assessment capacity may be insufficient to meet the needs of the many small and medium-sized businesses (SMBs) seeking certification, given the rigorous and resource-intensive nature of the CMMC assessment process. The high demand emphasizes the need for timely scheduling and thorough planning (CyberAB, Taft Privacy & Data Security Insights; MxD; CMMC Audit Preparation; PreVeil).

Typical timelines for achieving CMMC Level 2 certification range from 6 to 12 months, depending on factors like existing cybersecurity posture and resource allocation. Organizations without existing cybersecurity measures may require 18 to 24 months to achieve certification (CMMC Audit Preparation; ECURON; InterSec).

Market Feasibility

The global cybersecurity market is projected to expand from USD 190.4 billion in 2023 to USD 298.5 billion by 2028, with a compound annual growth rate (CAGR) of 9.4% (MarketsandMarkets). This growth is driven by the increasing frequency and complexity of cyberattacks, along with the rising demands placed on businesses, governments, and individuals to enhance their cybersecurity measures. The U.S. Department of Defense (DoD) has allocated approximately $401 billion—nearly 49% of its total $842 billion Fiscal Year 2024 budget—for contract obligations (Defense Comptroller). This budget includes a historic $170 billion for procurement, the largest ever (Federal Budget IQ), aimed at acquiring the weapons, equipment, and services necessary to maintain and improve military operational capabilities. DoD Defense Industrial Base (DIB) contractors are integral to these procurement efforts, underscoring the critical importance of robust cybersecurity measures.

CMMC Level 2 requirements are mandated for all DoD contracts involving CUI, with exceptions only for contracts that exclusively pertain to commercial off-the-shelf (COTS) items. The DoD anticipates that 220,000 companies -the DIB encompasses roughly 300,000 companies (DoD)- will be affected by CMMC requirements in general, and CMMC Level 2 applies to over 80,000 entities (about 36%) of those contractors (Wiley, Blank Rome). Achieving CMMC Level 2 certification not only aligns with the DoD’s significant emphasis in cybersecurity but also presents substantial opportunities for certified businesses within both the broader cybersecurity market and the DoD’s defense sector (USFCR).

Financial Impact of Non-Compliance

Failing to achieve the required CMMC certification by 2025 could lead to significant financial losses for all contractors. The potential revenue loss includes:

Immediate Revenue Loss: Government contractors often rely heavily on a few key contracts. The value of these contracts can range widely, but for many small businesses, a single contract can be worth anywhere from $100,000 to several million dollars annually.

Dependency on DoD Contracts: Many DIBs primarily serve the DoD. Failing to get certified could result in losing most or all of their revenue. For example, if a business has $1 million in annual revenue from DoD contracts, failing to certify would mean losing this revenue entirely.

Future Opportunities: The lack of CMMC Level 2 certification will make businesses ineligible to compete for an estimate of over $100 billion of the larger $401 billion budget allocated for DoD contract obligations.

Benefits of Compliance

Achieving CMMC Level 2 certification provides several key benefits for small and medium-sized businesses (SMBs), including:

Regulatory Compliance: Ensures adherence to stringent cybersecurity practices required by the DoD, thereby enhancing the credibility and market positioning of SMBs.

Market Opportunities: Opens doors to new opportunities with other federal agencies and commercial entities, supporting business continuity and growth.

Competitive Edge: Prevents the loss of DoD contracts and supports long-term resilience by complying with CMMC requirements.
