CMMC Compliance Cost Breakdown: DIY vs. Consultant vs. Platform

The Real Cost of CMMC Compliance

If you're a defense contractor handling CUI, CMMC Level 2 is no longer optional. But the cost of getting compliant varies wildly depending on your approach — from a few hundred dollars to well over six figures.

Let's break down the three most common paths and their real costs, including the hidden expenses most guides skip.

Option 1: Hire a Consultant ($35,000 – $75,000+)

This is the traditional path. A GRC consulting firm comes in, assesses your environment, builds your documentation, and helps you through the assessment process.

Typical Cost Breakdown
ItemCost Range
Gap assessment$5,000 – $15,000
SSP development$10,000 – $25,000
Policy creation (14 families)$8,000 – $20,000
POA&M development$2,000 – $5,000
Assessment preparation$5,000 – $10,000
Ongoing support (annual)$5,000 – $15,000/year
**Total (Year 1)****$35,000 – $75,000+**
Pros
  • Expert guidance through the entire process
  • Customized to your specific environment
  • Assessor relationship and assessment prep
Cons
  • High upfront cost — prohibitive for small contractors
  • Dependent on consultant availability (long wait times in 2026)
  • Documentation may not be easily maintained after engagement ends
  • You're paying for their time, not a reusable system
When This Makes Sense

Large organizations (500+ employees) with complex CUI environments and budget for a dedicated compliance program.

Option 2: Do It Yourself ($500 – $5,000)

Some organizations attempt to build all documentation from scratch using free NIST resources and guidance documents.

Typical Cost Breakdown
ItemCost Range
NIST publications (free)$0
Generic templates$200 – $500
Staff time (200-500 hours)$10,000 – $50,000*
Training and learning curve$500 – $2,000
**Total (out of pocket)****$500 – $5,000**

*Staff time is the hidden killer. At $50/hour, 300 hours of compliance work costs $15,000 in labor — even if no money changes hands.

Pros
  • Lowest out-of-pocket cost
  • Full control over the process
  • Deep organizational learning
Cons
  • Massive time investment (6-18 months)
  • High risk of documentation gaps or errors
  • No expert review before assessment
  • Staff pulled away from their primary responsibilities
  • Easy to underscope or miss requirements
When This Makes Sense

Organizations with an experienced GRC team already on staff and time to dedicate to the process.

Option 3: Interactive Compliance Platform ($997 – $5,964/year)

This is the approach we built our platform around: guided, interactive tools that walk you through the process with expert-built questions and templates — without the consulting price tag.

Typical Cost Breakdown (Our Platform)
ItemCost Range
Starter (Level 1)$997 one-time
Professional (Level 2)$250/month ($3,000/year) or $2,268/year (annual)
Enterprise (Level 3 + Consultant Tools)$497/month ($5,964/year) or $4,488/year (annual)
Staff time (50-100 hours)$2,500 – $5,000*
**Total (Year 1, Professional)****$4,288 – $7,364**

*Interactive questionnaires reduce staff time by 60-80% compared to DIY because the questions guide you through exactly what to document.

What You Get
  • **Interactive dashboard** with real-time SPRS score tracking
  • **20 guided questionnaires** (566 questions) covering every control family
  • **110-control tracker** for managing implementation status
  • **Compliance checker** for scoring existing documents
  • **30+ audit-ready templates** (SSP, POA&M, policies, workbooks)
  • **CUI and network boundary builders**
  • Built by a CISSP/CCP with real CMMC Level 2 assessment experience
Pros
  • 90% cheaper than consultants
  • Structured guidance eliminates guesswork
  • 60-80% less staff time than DIY
  • Templates formatted for C3PAO review
  • Reusable year after year for ongoing compliance
Cons
  • Still requires internal effort and ownership
  • Not a substitute for C3PAO assessment itself
  • Complex or unique environments may still need some consulting
When This Makes Sense

Small to mid-size defense contractors (10-500 employees) who need structured guidance but can't justify $35K+ for a consultant.

The Hidden Costs Everyone Forgets

Regardless of which path you choose, budget for these often-overlooked expenses:

C3PAO Assessment Fee

The assessment itself typically costs **$25,000 – $75,000** depending on the size and complexity of your environment. This is separate from all preparation costs.

Technical Controls Implementation

CMMC isn't just documentation. You may need to implement or upgrade:

  • Multi-factor authentication (MFA)
  • SIEM/log management
  • Endpoint detection and response (EDR)
  • Encrypted email and file sharing
  • Network segmentation
  • Backup and disaster recovery

Budget **$10,000 – $50,000+** for technical tooling, depending on your current maturity.

Annual Maintenance

CMMC isn't a one-time certification. You need ongoing:

  • Annual self-assessments
  • Policy reviews and updates
  • Security awareness training
  • Continuous monitoring
  • Incident response testing
Staff Training

Your team needs to understand their security responsibilities. Budget for:

  • Security awareness training for all CUI-handling personnel
  • Role-based training for IT and security staff
  • Assessment preparation for leadership

Our Recommendation

For most small-to-mid defense contractors, the **platform approach** offers the best balance of cost, quality, and time. You get the structured guidance of a consultant at a fraction of the price, with tools that support ongoing compliance — not just a one-time engagement.

If your environment is particularly complex or you need hands-on help, start with the platform to get your documentation 80% complete, then bring in a consultant for the final 20%. This hybrid approach can save $20,000+ compared to using a consultant from scratch.
