# CMMC 2.0 Compliance Software for Defense Contractors CMMC 2.0 is not a suggestion. It is a contract eligibility requirement. The Department of Defense finalized the CMMC Program rule (32 CFR Part 170) in October 2024, and CMMC requirements are now ap... ## CMMC 2.0 Compliance Software for Defense Contractors Custom software that implements all 110 NIST SP 800-171 controls, manages your System Security Plan, tracks POA&M remediation, automates SPRS scoring, and prepares your organization for C3PAO assessment. FreedomDev builds CMMC Level 2 compliance platforms for small and mid-size defense contractors who handle Controlled Unclassified Information — with 20+ years delivering regulated software for the defense industrial base. --- ## Our Process 1. **CUI Scoping and Gap Assessment (2–3 Weeks)** — We start by defining what needs to be protected and where it lives. Working with your contracts team, we identify every active DoD contract that involves CUI, catalog the CUI categories and marking indicators (per DoDI 5200.48 and the CUI Registry), and trace CUI data flows through your environment — from receipt through processing, storage, transmission, and disposal. We then map your current security posture against all 110 NIST SP 800-171 practices, scoring each as Not Implemented, Partially Implemented, or Fully Implemented with evidence. Deliverable: a CUI boundary definition, a gap assessment report with your current SPRS score, and a prioritized remediation roadmap with cost and timeline estimates for each practice. 2. **CUI Enclave Design and Boundary Reduction (2–4 Weeks)** — The highest-ROI activity in any CMMC program is reducing your assessment boundary. We design a CUI enclave — a network-segmented environment with controlled access where all CUI processing occurs — so that the 110 controls apply only to the enclave, not your entire corporate network. This involves VLAN segmentation or physical network separation, dedicated CUI workstations or virtual desktop infrastructure, separate Active Directory organizational units with enclave-specific group policies, controlled data transfer mechanisms between the enclave and your corporate environment, and boundary defense devices (firewalls, proxies) at every ingress and egress point. Boundary reduction typically cuts assessment scope by 60 to 80 percent and is the single most cost-effective compliance investment. 3. **Technical Control Implementation (4–8 Weeks)** — We implement the technical controls required by each NIST 800-171 practice across your CUI environment. Access Control: role-based access with least privilege, multi-factor authentication for all CUI system access, session controls, remote access through managed VPN. Audit and Accountability: SIEM deployment or configuration, comprehensive event logging, tamper-evident log storage, automated log review rules. Configuration Management: baseline configurations for all CUI systems, change control workflows, vulnerability scanning and remediation cycles. System and Communications Protection: FIPS 140-2 validated encryption for CUI in transit and at rest, network boundary protections, DNS filtering, email security controls. Identification and Authentication: centralized identity management, password complexity enforcement, privileged account management. Each control is documented with implementation evidence linked directly to the corresponding NIST practice number. 4. **Compliance Platform Deployment and SSP Generation (3–4 Weeks)** — We deploy the CMMC compliance platform configured for your environment: all 110 practices loaded with your specific implementation details, evidence artifacts linked, POA&M items created for any remaining gaps, SPRS score calculated, and SSP generated from live data. Your team receives role-specific training — IT administrators learn the technical control monitoring dashboards, compliance officers learn the evidence management and SSP workflows, and executives learn the SPRS score tracking and assessment readiness views. The platform integrates with your existing IT systems through the API connections needed to pull live configuration data, audit logs, and vulnerability scan results into the compliance evidence repository. 5. **Mock Assessment and C3PAO Preparation (2–3 Weeks)** — We conduct a full mock assessment using the CMMC Assessment Guide methodology. Every practice is evaluated the way a C3PAO assessor would evaluate it: evidence is reviewed, configurations are verified, personnel are interviewed about their responsibilities under each control family, and the SSP is compared against the operational reality. Practices that would receive Not Met or partially implemented findings get immediate remediation attention. We prepare the specific documentation packages that C3PAO assessors request on day one of assessment: the SSP, the network diagram, the CUI boundary documentation, the POA&M (if applicable), the asset inventory, and the policy and procedure library mapped to each control family. When the C3PAO arrives, your team knows exactly what to expect because they have already been through the process. --- ## Frequently Asked Questions ### What is CMMC 2.0 and which level do most defense contractors need? CMMC 2.0 (Cybersecurity Maturity Model Certification) is the Department of Defense's framework for verifying that defense contractors implement adequate cybersecurity controls to protect Controlled Unclassified Information (CUI) and Federal Contract Information (FCI). The framework has three levels. Level 1 requires 17 basic cyber hygiene practices from FAR 52.204-21 and applies to contractors who handle only FCI — not CUI. Level 1 allows annual self-assessment. Level 2 requires full implementation of all 110 security practices from NIST SP 800-171 Revision 2 and applies to contractors who handle CUI. Level 2 requires third-party assessment by an authorized C3PAO for contracts involving critical national security information, though some Level 2 contracts may allow self-assessment for non-critical CUI. Level 3 requires 110+ practices from NIST SP 800-171 plus additional controls from NIST SP 800-172, assessed by the Defense Contract Management Agency (DCMA) with support from the Defense Industrial Base Cybersecurity Assessment Center (DIBCAC). Level 3 applies to the highest-priority programs involving the most sensitive CUI. Most small and mid-size defense contractors need Level 2 because CUI appears on the vast majority of DoD contracts — technical drawings, specifications, test data, manufacturing processes, logistics information, and export-controlled data all qualify as CUI under DoDI 5200.48. If your contract includes DFARS 252.204-7012, you are handling CUI and need Level 2. ### How much does CMMC Level 2 compliance cost for a small defense contractor? Total cost depends on your starting security posture, the size of your CUI environment, and whether you reduce scope through enclave architecture. For a small defense contractor with 20 to 100 employees who is starting from a typical posture — basic antivirus, simple passwords, no encryption, no SIEM, no formal incident response — the total cost to achieve CMMC Level 2 breaks down into four categories. Technical control implementation covers the hardware, software, and configuration changes needed to satisfy the 110 practices: SIEM or managed SOC ($15,000 to $60,000 per year), endpoint detection and response ($5 to $15 per endpoint per month), FIPS 140-2 validated encryption ($5,000 to $20,000), multi-factor authentication ($3 to $10 per user per month), vulnerability management tools ($5,000 to $25,000 per year), backup and recovery infrastructure ($10,000 to $30,000), and network segmentation equipment for CUI enclave ($10,000 to $50,000). Professional services cover gap assessment, enclave design, control implementation, SSP development, and mock assessment — typically $80,000 to $200,000 with FreedomDev, or $50,000 to $150,000 for documentation-only consulting that does not include technical implementation. The C3PAO assessment itself costs $30,000 to $120,000 depending on scope. Ongoing compliance maintenance — monitoring, log review, vulnerability remediation, annual reassessment preparation — runs $2,000 to $8,000 per month. Total first-year cost for a 50-person contractor ranges from $150,000 to $400,000. The single most effective cost reduction is CUI boundary scoping. Reducing your assessment boundary from 200 endpoints to 40 endpoints through enclave design can cut technical control costs by 60 to 80 percent. FreedomDev's approach prioritizes enclave design before control implementation specifically because the boundary reduction pays for itself multiple times over. ### What is a System Security Plan and why is it critical for CMMC assessment? The System Security Plan is the primary document that a C3PAO assessor evaluates during a CMMC Level 2 assessment. NIST SP 800-171 practice 3.12.4 requires organizations to develop, document, and periodically update system security plans that describe the system boundary, the operational environment, how security requirements are implemented, and the relationships with or connections to other systems. In practice, the SSP is a detailed document (typically 100 to 300 pages for a Level 2 environment) that contains your system boundary description and network diagrams, your CUI data flow documentation showing how CUI enters, moves through, is stored in, and exits your environment, a practice-by-practice description of how each of the 110 NIST 800-171 controls is implemented in your specific environment, the roles and responsibilities for security functions, interconnection security agreements with external systems, and the current status of any Plans of Action and Milestones. The assessor compares your SSP against what they observe in your actual environment. Every discrepancy between the SSP and reality is a finding. An SSP that describes multi-factor authentication but your systems only use passwords is a finding. An SSP that claims CUI is encrypted at rest but your file server uses unencrypted storage is a finding. An SSP that documents a CUI boundary but your network diagram shows uncontrolled data paths outside that boundary is a finding. This is why FreedomDev generates the SSP from live system data rather than from a static template — the SSP must reflect your actual security posture at the time of assessment, and a document that was accurate six months ago is almost certainly inaccurate today. ### What are POA&Ms and can you still pass CMMC with open POA&M items? A Plan of Action and Milestones is a documented plan to remediate security control deficiencies that have been identified but not yet fully addressed. Under CMMC 2.0, POA&Ms are permitted under specific conditions. You can receive a conditional CMMC Level 2 certification with open POA&M items, but only if the practices in question are partially implemented — meaning some implementation exists and is operational, just not complete. Practices with zero implementation cannot be placed on a POA&M — they are assessed as Not Met and prevent certification entirely. The conditional certification requires that all POA&M items be remediated within 180 days. If you do not close all POA&M items within 180 days, your conditional certification is revoked. Additionally, there are practices that are not eligible for POA&M treatment at all. The CMMC program has designated certain high-impact practices where partial implementation is considered unacceptable — these must be fully implemented at the time of assessment. The practical implication is that POA&Ms are a safety valve for near-miss findings, not a workaround for significant gaps. A contractor with 5 practices on POA&M that need minor configuration changes and documentation updates will likely succeed within the 180-day window. A contractor with 30 practices on POA&M that require new infrastructure, staff training, and process redesign will almost certainly fail to remediate in time. FreedomDev's compliance platform tracks each POA&M item with milestone dates, responsible parties, evidence requirements, and an automated countdown against the 180-day deadline — because missing that deadline is not a soft consequence. It means you lose your certification and have to go through the entire assessment process again. ### How does SPRS scoring work and why does it matter before CMMC assessment? The Supplier Performance Risk System score is a numerical representation of your NIST SP 800-171 compliance posture, calculated using the DoD Assessment Methodology. A perfect score is 110, representing full implementation of all 110 practices. Each unimplemented practice carries a weighted deduction of 1, 3, or 5 points based on the security significance of the practice. For example, failing to implement multi-factor authentication (a 5-point practice) costs five times more than failing to implement certain lower-impact awareness and training requirements (1-point practices). SPRS scores range from -203 (no practices implemented, maximum deductions applied) to 110 (full implementation). DFARS 252.204-7019 and 252.204-7020 require contractors to conduct a self-assessment using the DoD Assessment Methodology and report the resulting score to SPRS. Contracting officers and prime contractors can view these scores, and they are increasingly used as source selection criteria — a contractor with an SPRS score of 95 is a visibly lower risk than one scoring 47. Some primes now require minimum SPRS scores for subcontract eligibility, effectively creating a market-driven compliance incentive that operates independently from the CMMC assessment timeline. Your SPRS score also tells you exactly where you stand before you spend money on a C3PAO assessment. A score of 95 with a few minor gaps is assessment-ready. A score of 50 means you have 40 to 60 practices that need implementation — which is 6 to 12 months of remediation work, not a quick fix. FreedomDev's platform calculates your SPRS score in real time from your actual implementation status, identifies the highest-weighted gaps, and prioritizes remediation for maximum score improvement per dollar spent. ### What is CUI, how do we identify it, and what contracts require CUI protection? Controlled Unclassified Information is information that the government creates or possesses, or that a contractor creates or possesses on behalf of the government, that requires safeguarding or dissemination controls consistent with applicable laws, regulations, and government-wide policies. CUI is not classified information — it does not carry Secret or Top Secret markings. But it is sensitive enough that the government has determined it requires protection beyond what is appropriate for public information. CUI categories are defined in the CUI Registry maintained by the National Archives (32 CFR Part 2002) and include categories directly relevant to defense contractors: Controlled Technical Information (CTI) covering specifications, drawings, and technical data for defense articles; Export Controlled information subject to ITAR or EAR; Naval Nuclear Propulsion Information; operations security information; and critical infrastructure security information. Your DoD contracts specify CUI requirements through several mechanisms. DFARS 252.204-7012 (Safeguarding Covered Defense Information and Cyber Incident Reporting) is the primary clause — if it appears in your contract, you are handling CUI and must implement NIST SP 800-171. The contract's DD Form 254 identifies specific security requirements. The contract CDRL (Contract Data Requirements List) items may be marked with CUI banners. In practice, CUI appears on far more contracts than contractors realize. Engineering drawings, test procedures, performance specifications, manufacturing process documentation, logistics data, and even meeting minutes discussing technical details of defense systems can constitute CUI. The safest assumption for any defense contractor is: if the data relates to a DoD system or program and is not already public, treat it as CUI until you confirm otherwise with your contracting officer. ### What is a C3PAO and how do we choose one for our CMMC assessment? A CMMC Third-Party Assessment Organization (C3PAO) is an organization authorized by the Cyber AB (formerly the CMMC Accreditation Body) to conduct CMMC Level 2 assessments. C3PAOs employ certified CMMC assessors who evaluate your security controls, review your documentation, interview your personnel, and examine your technical environment to determine whether you meet all 110 NIST SP 800-171 practices. The assessment results in one of three outcomes: certification (all practices met), conditional certification (some practices on POA&M with 180-day remediation window), or no certification (too many gaps or unimplementable practices found). Choosing a C3PAO involves several considerations. First, verify authorization — only organizations listed on the Cyber AB marketplace are authorized to conduct assessments. Any firm offering CMMC certification that is not on that list is not legitimate. Second, check experience — some C3PAOs focus on small contractors while others specialize in larger enterprises or specific defense sectors. Ask how many assessments they have completed and the size and complexity of those environments. Third, understand the scope and pricing — assessment costs vary significantly ($30,000 to $120,000) based on the size of your CUI boundary, number of locations, number of systems in scope, and the C3PAO's pricing model. Get the scope explicitly defined in writing before signing. Fourth, check availability — the number of authorized C3PAOs is still growing and assessment scheduling backlogs exist. Book early. Finally, understand what the C3PAO does not do. A C3PAO assesses your compliance — it does not help you achieve it. If a C3PAO is also offering to sell you consulting services to prepare for their own assessment, that is a conflict of interest that the Cyber AB guidelines prohibit. FreedomDev prepares you for assessment; the C3PAO independently evaluates the result. ### How do we define and reduce our CUI boundary to lower CMMC compliance costs? Your CUI boundary — also called the assessment scope or CMMC assessment boundary — includes every system, network segment, application, and storage location that stores, processes, or transmits CUI, plus every system that provides security protection for those CUI assets (firewalls, SIEM, DNS servers, Active Directory domain controllers, etc.). The larger this boundary, the more systems must implement all 110 controls, the more the assessment costs, and the more surface area exists for assessment findings. Most contractors start with CUI spread across their entire enterprise network — engineering files on general file shares, CUI in email inboxes across the organization, technical data on employee laptops that also browse the internet and run personal applications. In this scenario, every endpoint, server, network device, and cloud service in your entire organization is in scope. Boundary reduction works by consolidating CUI handling into a dedicated enclave. The enclave is a defined network segment (VLAN or physically separate network) with its own access controls, dedicated workstations or VDI, dedicated file storage, and controlled data transfer mechanisms to and from the corporate network. CUI is stored and processed only within the enclave. Users access the enclave through controlled access points with multi-factor authentication. Data leaving the enclave goes through a managed transfer process that logs and controls every export. The corporate network outside the enclave does not handle CUI and is therefore out of scope for CMMC assessment. A company with 300 employees and 400 total endpoints might reduce its assessment scope to a 40-endpoint CUI enclave where only the 30 employees who actually need CUI access work. Instead of implementing SIEM monitoring, endpoint detection, FIPS 140-2 encryption, and all other controls across 400 endpoints, you implement them across 40. The cost difference is massive. FreedomDev designs CUI enclaves as a standard part of every CMMC engagement because the scope reduction pays for the enclave infrastructure multiple times over in reduced control implementation and assessment costs. --- **Canonical URL**: https://freedomdev.com/solutions/cmmc-compliance _Last updated: 2026-05-12_
