Think CMMC Is Overwhelming? You May Already Be on the Right Track

If hearing “CMMC” makes your stomach drop – you are not alone. Most businesses we talk to feel overwhelmed the moment the Cybersecurity Maturity Model Certification (CMMC) comes up. We hear the same reactions over and over:

“We’ll never meet those requirements. It sounds impossible.”

“We don’t have the staff or budget to handle this.”

“We don’t even work directly for the government—why is this even our problem?”

We get it. Really — we’ve been there too.

But here’s the truth no one’s saying loud enough: You (yes YOU) are probably already doing more than you realize. And for many companies, those scary “government-specific” parts? They may not even apply.

Let’s break the myths wide open — and show you why CMMC doesn’t have to be a monster under the bed.

What is CMMC really asking for?

CMMC is not asking you to completely rebuild your IT systems or hire a 24/7 security team. It’s just a way to make sure businesses (especially those working with the Department of Defense) are following foundational cybersecurity best practices that any good business should be doing anyway.

Even if you never touch a government contract, these practices protect your data, reputation, customers, and operations.

So… what are these mysterious CMMC “controls”? Let’s take a look at what you probably already have in place.

The 14 Control Families from NIST 800-171 revision 2

#  Control family  What CMMC calls for  Everyday best-practice examples 
1  Access Control  Limit who can get to what, and what they can do once inside Unique log-ins, least-privilege roles, MFA on email/VPN
2  Awareness & Training  Make sure staff know how to spot and report threats Phishing simulations during onboarding and quarterly refreshers
3  Audit & Accountability  Generate & keep the logs you’d need in an investigation Centralized log retention in Microsoft Sentinel, 90-day hot / 1-year cold
4  Configuration Management  Maintain secure, documented baselines Intune/MDM policies that enforce BitLocker, firewall, and USB blocking
5  Identification & Authentication  Verify every user, device, service SSO with conditional access—no SMS codes, only authenticator apps 
6  Incident Response  Detect threats, contain, eradicate, recover, learn One-page IR playbook + quarterly tabletop
7  Maintenance  Safely service hardware & software Patch Tuesdays scripted via WSUS/Intune; vetted remote vendors only
8  Media Protection  Protect data on removable media & backups Encrypt USBs; shred drives; cloud backups with object-lock
9  Personnel Security  Screen, onboard, and off-board people securely Background checks; day-zero account disablement & badge return
10  Physical Protection  Guard facilities & equipment Smart-card entry, visitor sign-in, CCTV on server room
11  Risk Assessment  Periodically analyze cyber-risk Conduct an annual third-party penetration test
12  Security Assessment  Self-assess & remediate gaps Internal scorecard vs. NIST 800-171; POA&M (Plan of Actions & Milestones) reviewed each quarter
13  System & Comms Protection  Segment networks, encrypt data, control traffic VLANs for guest Wi-Fi; TLS 1.2+ everywhere; deny-all firewalls
14  System & Info Integrity  Patch, scan, and monitor for compromise EDR with weekly vulnerability scans, 24×7 SOC alerting

What is TRULY different about CMMC?

Here is the part that confuses most people:

CMMC requirements don’t apply equally to everyone — but if they apply to you, they apply fully.

Whether you need to comply — and how strictly — depends on two key things:

  1. What your contract says, and
  2. Whether you’re expected to handle Controlled Unclassified Information (CUI).

What Is CUI and Why Does It Matter?

Controlled Unclassified Information (CUI) is unclassified data that still requires protection under federal law or policy. It often shows up in government contracts or DoD-related work — but it’s not as mysterious as it sounds (See the DoD CUI Registry for the full list).

Think of CUI as high-value business information you’d already want to protect, like:

  • Technical drawings or engineering schematics

  • Part numbers, manufacturing instructions, or configuration data

  • Test results, reports, or documents shared by the DoD

  • PII, payroll records, or proprietary recipes tied to a government contract

The same criminals who want your customer list would happily ransom DoD schematics. So treat CUI like any other business-critical secret:
Encrypt it. Limit access. Know where it lives.

Clauses to Watch For

If your DoD contract includes any of the following, CMMC applies:

Regulation Clause  What it says in plain English 
FAR  52.204-21 “Basic Safeguarding of Covered Contractor Information Systems”  All federal contractors must implement 15 basic cyber safeguards, mirroring CMMC Level 1 acquisition.gov 
DFARS  252.204-7012 “Safeguarding Covered Defense Information & Cyber-Incident Reporting”  Must follow NIST 800-171 (110 controls) and report breaches within 72 h acquisition.gov 
  252.204-7019 “Notice of NIST 800-171 DoD Assessment”  Requires an up-to-date SPRS (Supplier Performance Risk System) score before award 
  252.204-7020 “NIST 800-171 DoD Assessment Requirements”  Grants DoD the right to audit your score 
  252.204-7021 “CMMC Requirements”  You must hold—and keep— the required CMMC certificate throughout the contract acquisition.gov 

Here’s the Catch

Even if you don’t think you’re handling CUI, if your contract includes the clause DFARS 252.204-7012, you are:

  • Required to implement all 110 NIST SP 800-171 controls, and
  • Expected to be ready to protect CUI at any time during contract performance.

That’s right, it’s not about whether you’ve received CUI yet. If your contract says you need to protect it, you must be capable of doing so. This means the moment your environment is eligible to receive CUI, you’re on the hook — whether that data has been shared or not.

The Controls That Set CMMC Level 2 Apart

The truth is, most of the 110 controls in NIST SP 800-171 Rev. 2 are simply cybersecurity best practices — things every business should be doing, regardless of contract requirements. But not all of them deal directly with Controlled Unclassified Information (CUI).

Below are specific requirements that either: explicitly reference CUI, or involve DoD-unique data handling rules. Once your core security program is in place, these are the ones to tackle with special attention because they directly affect how you protect sensitive government data.

Control # Short Title What it means…
3.1.3, 3.1.20 Control the flow of CUI Make sure sensitive files can travel only along approved paths (no Dropbox leaks)
3.1.9 CUI Use Notices Display “you’re accessing CUI” banners on log-in
3.1.19 Encrypt CUI on Mobile Full-disk or container encryption on laptops, phones
3.1.22 No Public CUI Block posting CUI on public-facing websites
3.8.1-3.8.6, 3.8.9 Media controls Mark, encrypt, track, and destroy CUI on USBs, drives, backups
3.10.6 CUI at Alternate Work Sites Home offices must protect CUI just like HQ
3.11.1 Risk Assessment (CUI focus) Evaluate how CUI could be stolen or exposed
3.13.8, 3.13.11, 3.13.16 Encrypt CUI in transit, use FIPS crypto, protect CUI at rest Use FIPS-validated algorithms and crypto-erase disks
3.10.3, 3.14.6 Visitor escort, CUI markings on screens, CUI traffic monitoring Protect areas or logs because CUI is present

Where you may need to improve

Let’s be honest, no one has a perfect security program. And that’s okay. But if you’re serious about protecting your business (and preparing for CMMC), these are the 10 “must-have” security controls we see missing most often in small and mid-sized organizations.

#  Control family  What it is & why it matters  Typical SMB reality 
Multi-Factor Authentication Stops >99 % of password attacks; required on all remote access  MFA on O-365, but VPN & legacy apps still password-only 
Asset & Software Inventor  You can’t secure what you don’t know exists  Spreadsheets; shadow SaaS untracked 
Regular Patching  Closes known holes attackers automate against  Windows auto-update on; firewalls, firmware often months behind 
Central Log Collection Provides evidence when things go wrong  Logs live only on the device until they roll off 
Tested, Off-Site Backups Last line of defense vs. ransomware  Backups exist—but no one has ever done a full restore 
Documented IR Plan Chaos is expensive; scripts your first 48 hours  “Call IT” is the whole plan 
Security Awareness Training Employees are target #1  One-off lunch-and-learn, no follow-up phishing tests 
Network Segmentation  Prevents malware from pivoting everywhere  Flat network + guest Wi-Fi on same subnet 
Vendor / Cloud Access Review  Third parties inherit your risk  Dormant admin accounts for ex-vendors linger for years 
10  Formal Risk Assessment  Aligns spend with real business threats  Never documented; decisions driven by “what broke last” 

The Real Story: CMMC is not some government monster

We’ve helped plenty of businesses navigate CMMC 2.0, and here’s what the process actually looks like:

✅ Most companies are already 40–80% of the way there — they just don’t realize it.
✅ The truly government-specific controls — things like CUI handling, visitor escorts, and data labeling — only apply if your contract explicitly requires it.
✅ And even if you never plan to work with the DoD, building a security program like this will make your company safer, more resilient, and more competitive.

Bottom line: CMMC is just formalized cyber hygiene — with a few extra rules if you’re working with sensitive government data.

Ready to Go?

Here’s Your 12-Week Sprint to CMMC Compliance

If you’re ready to move, you don’t need a year-long project plan or endless meetings. Here’s a 12-week, DevOps-style roadmap designed to help SMBs build momentum fast — and reach CMMC Level 2 readiness without burning out.

Each phase builds on the last — short sprints, fast wins, and visible progress.

Sprint  Goal  Key actions  Owner suggestions 
Weeks 1-2  Define Scope & Inventory Assets Identify in-scope systems, users, data flows, cloud services. Build asset inventory and system boundary map. IT Lead or System Administrator
3-4 Harden Identity & Access Controls Implement MFA, least privilege, account management policy, session locks, and admin account separation. IT Security or Network Admin
5-6 Patch Management & System Hardening Apply critical updates, configure secure baselines (CIS/NIST), and standardize patch cadence. Review GPOs, firewall settings, and endpoint protections. IT Lead or System Administrator
7-8 Write Core Documentation Draft the SSP (System Security Plan), create the POA&M, and document your overall architecture and gaps. Compliance Manager
9-10 Develop and Finalize Key Policies Write and adopt core policies: Access Control, Incident Response, Configuration Management, Media Protection, etc. Route for review/approval. Compliance Manager or Policy Owner
11-12 Validate & Finalize Security Readiness
 
Test security controls, implement CUI safeguards, and update documentation to finalize audit readiness. Compliance Manager + IT Security Lead (Joint Ownership)

Sprint Mechanics: Hold a 30-min planning meeting on Day 1, a 15-min stand-up each day, and a retrospective on the last Friday. Track tasks on a Kanban board—just like your dev team. 


Final Thought: It’s not about “Government Work.” It’s about being secure for your customers and your business.

Whether or not you care about DoD contracts, CMMC pushes you toward smart, modern cybersecurity that protects your business from ransomware, phishing, lawsuits, downtime, and lost revenue.

CMMC is worth doing – even without a government badge.
