Well, it finally happened. The waiting game is over. As of November 10th, 2025, CMMC requirements become officially mandatory in DoD contracts. If you’re handling Controlled Unclassified Information (CUI), which about 80k defense contracts are, the “we’ll deal with it later” era just ended.
Listen, nobody’s excited about this. It’s expensive, time consuming, and can feel like yet another compliance hurdle in an already complicated world. The final rule (48 CFR) hit the Federal Register on September 10th, 2025, and now everyone is trying to figure out how to get this done without breaking the bank or losing our minds.
There is good news. You’re not alone in this, and it’s absolutely doable with the right approach.
What Just Changed (And What It Means for You)
Let's cut right to it: Starting November 10, 2025, DoD contracts involving CUI require CMMC Level 2 compliance. This isn't the end of the world. It's just the new reality we're navigating together.
The rollout happens in phases, which at least gives us some breathing room:
Phase 1 (November 10, 2025): Self-assessments for Level 1 and Level 2 start appearing in contracts. The DoD can also require third-party assessments for high-priority contracts at their discretion. This is happening right now.
Phase 2 (November 10, 2026): Third-party certification assessments become mandatory for Level 2. That's when a certified CMMC Third-Party Assessor Organization (C3PAO) comes in to verify you're actually doing what you say you're doing.
Phase 3 (November 10, 2027): Level 3 requirements kick in for the highest-priority programs.
Here's the reality: it takes most defense contractors 6-12 months to get assessment-ready. If you're reading this and haven't started, yeah, you're a bit behind but so are a lot of other contractors. The key is to start now and make steady progress. And your prime contractors? Many are requiring CMMC compliance from their subs already, so this affects everyone in the supply chain.check your contracts ASAP!
The 110 Controls You Can't Ignore
CMMC Level 2 isn't an arbitrary checklist cooked up in a Pentagon basement. It's based on NIST SP 800-171, which has been the required standard for protecting CUI since 2017. The problem? Most contractors have been self-attesting compliance without anyone actually verifying it. Those days are over.
Level 2 requires you to implement all 110 security controls across 14 domains:
Access Control (22 controls): Who gets in, what they can touch, and how you're monitoring it all
Audit and Accountability (9 controls): Keeping track of who did what, when they did it, and why
Awareness and Training (3 controls): Making sure your team actually knows what they're supposed to be protecting
Configuration Management (9 controls): Keeping your systems locked down and documented
Identification and Authentication (11 controls): Proving you are who you say you are
Incident Response (4 controls): What happens when (not if) something goes wrong
Maintenance (6 controls): Keeping systems secure while keeping them running
Media Protection (9 controls): Protecting data wherever it lives
Personnel Security (2 controls): Vetting the humans with access to sensitive stuff
Physical Protection (6 controls): Old school security still matters
Risk Assessment (3 controls): Actually understanding what you're up against
Security Assessment (4 controls): Testing your defenses regularly
System and Communications Protection (16 controls): Protecting data in transit and at rest
System and Information Integrity (6 controls): Spotting and stopping malware and unauthorized changes
Each of these 110 controls breaks down into 320 specific assessment objectives that a C3PAO will evaluate. You need a minimum score of 88 out of 110 points (80% compliance) to pass. But here's the catch: certain critical controls are weighted heavier. Miss even one critical control, and you could tank your entire score.
The Real Talk on POA&Ms
The good news? While you must address and implement each control, you don't need a perfect 110/110 score to get certified. CMMC 2.0 allows for Plans of Action and Milestones (POA&Ms), basically documented promises to fix gaps within 180 days.
The bad news? C3PAOs are stingy with POA&Ms. They're only allowed for less critical controls, and you can't use them as a strategy to pass. If you're planning to rely heavily on POA&Ms, you're probably not ready for assessment.
What This Actually Costs (Spoiler: It's Not Cheap)
Let's talk money, because that's what keeps SMB owners up at night. Getting CMMC Level 2 ready isn't a "buy some software and check the box" situation. Here's what you're looking at:
The Assessment Itself: Expect to pay anywhere up from $35k-$100k for a C3PAO assessment. Larger or more complex environments? That number goes up fast.
Getting Ready: This is where the real costs hide. You'll need:
Technology upgrades (hello, AWS GovCloud/Microsoft GCC High or equivalent)
Documentation development (System Security Plans, policies, procedures)
Gap remediation (fixing all the stuff you're not doing yet)
Training for your team
Potentially hiring consultants or managed service providers
All told, many SMBs spend $50,000-$150,000 getting Level 2 ready, depending on how far they need to go. And that's not a one-time cost. You will need to maintain compliance, conduct annual self-assessments, and get re-certified every three years.
The Enclave Strategy (Or: How to Not Boil the Ocean)
Here's a secret that can save you serious money: you don't have to make your entire organization CMMC compliant. You can create a CMMC enclave, which is a segregated environment where CUI lives and operates under strict security controls, while the rest of your business continues as normal.
Think of it like a clean room in a manufacturing facility. You don't make the whole building into a clean room; you create one specialized space with the necessary controls. The same concept applies here.
An enclave approach means:
Lower technology costs (you're only securing part of your infrastructure)
Smaller assessment scope (fewer systems to audit)
Faster time to compliance
Less disruption to day-to-day operations
The trade-off? You need strict processes for how CUI enters and exits the enclave, and you need training to make sure people don't accidentally spread CUI outside the boundary. But for many SMBs, this is the difference between affordable compliance and going broke trying.
The Technology Stack That Actually Works
Let's get practical. What does a CMMC Level 2 compliant environment actually look like? Here are the must-haves:
FedRAMP Moderate (or equivalent) cloud infrastructure: AWS GovCloud or Microsoft 365 GCC High is the go-to for most contractors. It's designed specifically for this use case and covers many controls right out of the box. Yes, they are more expensive than their regular counterparts. But no, regular M365 and AWS won't cut it for CUI.
End-to-end encrypted communication: For email and file sharing involving CUI. Solutions like PreVeil or SecurelyShare handle this well.
Endpoint Detection and Response (EDR): You need to know what's happening on devices that touch CUI. Real-time monitoring and threat detection are non-negotiable.
Multi-Factor Authentication (MFA) everywhere: Passwords alone haven't been adequate security since approximately 2010. MFA is required for all CUI access.
Security Information and Event Management (SIEM): You need centralized logging and monitoring. This is how you prove you're actually watching for threats.
Vulnerability scanning and patch management: Regular scans and timely patching aren't optional. C3PAOs will check your patch logs.
The Documentation Nobody Wants to Write (But Everyone Needs)
CMMC assessors don't just check your technology, they check your documentation. No documentation = no compliance, even if your tech is perfect.
You'll need:
System Security Plan (SSP): This is your comprehensive document explaining how you meet all 110 controls. It's not a fun weekend project. Plan for weeks of work.
Policies and procedures: Written, approved, and actually followed. If your "incident response plan" is "call the IT guy and hope for the best," you're not ready.
Training records: Proof that your team completed required security awareness training annually.
Audit logs: Evidence that you're actually monitoring systems and reviewing logs regularly.
The silver lining? Once you've built this documentation framework, maintaining it is much easier than creating it from scratch.
What Happens If You Don't Comply
Let's be straight about the consequences, but also realistic. Here's what non-compliance means:
You won't be eligible for new contracts that require CMMC Level 2 certification. Your competitors who have certification will have an advantage when bidding.
Prime contractors need certified subs. If you can't certify, they'll need to find alternatives—not because they want to, but because their contracts require it.
Existing contracts typically aren't immediately affected, but any new task orders or modifications could trigger CMMC requirements.
There are no direct fines yet for non-compliance, but there is legal exposure if you misrepresent your compliance status. The False Claims Act applies to contract fraud, and nobody wants to go there.
The bottom line: this isn't optional if you want to keep working in the defense space. But with planning and the right approach, it's manageable.
The "We're Too Small For This" Reality Check
"CMMC is for big defense contractors, not companies our size."
We hear this a lot, but here's the thing: if you handle CUI—even as a subcontractor several layers down—CMMC applies to you. The requirements flow through the entire supply chain, regardless of company size.
SMBs often face unique challenges because you typically have fewer dedicated security resources and leaner budgets. That's exactly why getting expert help early can save you both time and money. The good news is that the enclave approach and smart technology choices can make this achievable without enterprise-level budgets.
The Next 90 Days: Your Action Plan
If you're just getting started (and many contractors are), here's a realistic roadmap:
Week 1-2: Assessment and scoping
Identify all locations where CUI lives in your organization
Decide whether you're going full-organization or enclave approach
Get a gap assessment from someone who specializes in CMMC
Week 3-4: Quick wins
Implement MFA everywhere
Start centralizing and reviewing audit logs
Document your current security policies (even if they're informal)
Begin required security awareness training
Month 2-3: Heavy lifting
Start technology migrations (GCC High, encrypted email, etc.)
Develop your System Security Plan
Remediate identified gaps
Create or update all required policies and procedures
Month 4-6: Polish and prep
Conduct internal testing against all 110 controls
Document everything that isn't already documented
Run tabletop exercises for incident response
Schedule your C3PAO assessment
This timeline is ambitious but achievable for organizations that commit resources and focus. It might take longer depending on your starting point—and that's okay. The important thing is making consistent progress.
Why This Actually Matters (Beyond Contract Eligibility)
Here's something that gets lost in all the compliance talk: CMMC Level 2 actually makes you more secure.
The 110 controls aren't arbitrary bureaucratic nonsense. They're based on decades of cybersecurity best practices and actual threat intelligence. Implementing them means you're genuinely harder to breach.
And in an era where defense contractors are getting hammered by increasingly sophisticated threat actors (many backed by nation-states) that matters. The CUI you're protecting isn't just "unclassified" data; it's information that, if compromised, could harm national security. That's why it's called controlled unclassified information.
You're not just checking boxes to win contracts. You're protecting information that matters, and building a security program that will serve your organization well beyond DoD work.
