If your business holds a Department of Defense contract — or wants one — the clock is ticking. On November 10, 2026, Phase 2 of the Cybersecurity Maturity Model Certification (CMMC) 2.0 rollout takes effect. Starting that date, the DoD will require third-party C3PAO assessments for Level 2 contracts. That means self-attestation alone is no longer enough. If you haven’t started preparing, five months isn’t much time — but it’s enough if you act now.
What CMMC Phase 2 Actually Means for Your Business
CMMC 2.0 is the Department of Defense’s framework for verifying that contractors and subcontractors properly protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). It replaced the older CMMC 1.0 structure with three streamlined levels:
- Level 1 (Foundational): 17 practices, self-assessment allowed
- Level 2 (Advanced): 110 practices aligned to NIST SP 800-171, third-party C3PAO assessment required starting Phase 2
- Level 3 (Expert): 110+ practices, government-led assessment
Most small-to-midsize defense contractors fall into Level 2 territory. During Phase 1 (November 2025 through November 2026), self-assessments were accepted for many Level 2 contracts. That window closes with Phase 2. After November 10, 2026, DoD solicitations will systematically require formal C3PAO audits for Level 2 certifications. Contractors who are not certified risk losing contract eligibility — and there is no grandfather clause for existing work if your contract comes up for renewal.
The 110 Controls You Need to Satisfy — and Where Most Businesses Fall Short
CMMC Level 2 maps directly to NIST SP 800-171, which covers 14 security domains and 110 individual controls. The most common gaps we see when working with defense contractors in Oklahoma City and Colorado Springs include:
- Multi-factor authentication (MFA): Required for all accounts accessing CUI — many small businesses still rely on passwords alone
- System and communications protection: Data must be encrypted in transit and at rest, including on endpoints
- Incident response planning: You must have a documented, tested IR plan — not just a rough outline
- Configuration management: Baseline configurations for all systems, with change control processes in place
- Media protection: Controls for how CUI is stored, transported, and destroyed on physical media
- Audit and accountability: Logging is required across systems that touch CUI, with log retention policies enforced
A gap assessment against these 110 controls is the essential first step. Without knowing exactly where you stand, you are guessing — and guesswork does not pass a C3PAO audit.
Understanding the C3PAO Assessment Process
A Certified Third-Party Assessment Organization (C3PAO) is an independent firm authorized by the Cyber AB to conduct formal Level 2 assessments. The assessment involves three methods defined by NIST:
- Examine: Document review — policies, procedures, System Security Plans (SSPs), and Plans of Action and Milestones (POA&Ms)
- Interview: Personnel verification — assessors speak with your staff to confirm practices match documentation
- Test: Technical verification — direct testing of system configurations, controls, and security tools
The process typically takes weeks of preparation and several days of active assessment. Findings are submitted to the CMMC Enterprise Mission Assurance Support Service (eMASS) and stored in the Supplier Performance Risk System (SPRS). Your SPRS score is visible to DoD contracting officers — a low score or failed assessment can disqualify you from new awards. Building a solid SSP and having your technical environment audit-ready before the C3PAO arrives is non-negotiable.
Why Waiting Until October Is a Dangerous Bet
Many contractors are taking a wait-and-see approach, assuming they have plenty of time. The reality is more compressed than it looks. Here is why:
- C3PAO capacity is limited. There are a finite number of accredited assessors nationwide, and demand is surging as the November deadline approaches. Scheduling slots in Q3 and Q4 2026 are already filling up.
- Remediation takes time. If your gap assessment reveals significant deficiencies — missing MFA, unencrypted CUI, no IR plan — you cannot fix those overnight. Technical remediation, policy documentation, and staff training all take weeks or months.
- New contracts may require it now. Even before Phase 2 officially begins, some DoD solicitations already list Level 2 C3PAO requirements. If a new opportunity comes up and you are not certified, you simply cannot bid.
- Subcontractors are included. CMMC flows down the supply chain. If you are a subcontractor to a prime, your prime may require your certification before awarding you work — often ahead of the DoD’s own deadlines.
The contractors in the best position come November are the ones who started gap assessments earlier in 2026 and are already in active remediation. Starting that process today — June 2026 — puts you just inside the window to be ready in time.
A Practical Roadmap: What to Do in the Next 90 Days
Here is the prioritized sequence for contractors who need to get CMMC-ready before Phase 2:
- Weeks 1 to 2: Scope your CUI environment. Identify every system, network, and user account that touches Controlled Unclassified Information. CUI scoping is the foundation — everything else follows from it.
- Weeks 2 to 4: Run a NIST SP 800-171 gap assessment. Score all 110 controls against your current environment. Document your System Security Plan (SSP) and identify gaps for your POA&M.
- Month 2: Begin technical remediation. Prioritize high-impact fixes — MFA deployment, endpoint encryption, log management, and network segmentation. These take the most time and often require vendor coordination.
- Month 2 to 3: Update policies and procedures. CMMC assessors review documentation as heavily as they review technical controls. Incident response plans, configuration management policies, and media handling procedures must be current and aligned with actual practice.
- Month 3: Schedule your C3PAO assessment. Do not wait until everything is perfect — schedule now to secure a slot. Most C3PAOs allow time between scheduling and the assessment start date, giving you runway to finish remediation.
How Degarmo Technologies Supports CMMC Readiness
Degarmo Technologies is a veteran-owned MSSP based in Oklahoma City with deep experience in NIST-framework compliance. Our team includes Information Systems Security Managers (ISSMs) and security engineers who have navigated compliance programs firsthand — not as consultants who learned CMMC from a slide deck, but as practitioners who have lived it in operational environments.
We offer end-to-end CMMC readiness support: gap assessments against NIST SP 800-171, SSP and POA&M development, technical remediation across endpoints, identity, and network layers, and ongoing managed security services to maintain your compliance posture after certification. For defense contractors in Colorado Springs — with its dense concentration of DoD-related businesses — and in Oklahoma City, we are positioned to act as both your readiness partner and your long-term security team.
The November 2026 deadline is real. The best time to start was six months ago — the second-best time is right now. Contact Degarmo Technologies for a free CMMC gap assessment consultation and find out exactly where your organization stands.
