Key Takeaways
- Most small suppliers spend far more on fixing gaps than on the assessment itself.
- Your CMMC level and the number of systems in scope drive the price more than company size.
- Scoping the work tightly before you buy anything can cut the bill sharply.
- Plan for yearly upkeep, not just a one-time project.
- Typical total budgets for a small San Diego supplier run from the low tens of thousands to well into six figures.
If you build parts, write software or supply services to a defense prime in San Diego, someone has probably asked about CMMC. The next question is always the same: what will this cost me? The honest answer starts with “it depends,” but that answer is only useful if you know what it depends on. This guide walks through the real cost pieces so you can build a budget instead of guessing.
The work usually falls into four buckets: scoping, fixing gaps, tools and licenses, and the formal assessment. A fifth cost keeps running after you pass, which is upkeep. Many owners only budget for the assessment and are surprised by the rest. A good starting point is a structured IT compliance consulting review that shows which of these buckets apply to you.
San Diego has a large defense and aerospace supply chain, from the Point Loma and Naval Base areas to Kearny Mesa machine shops and Carlsbad engineering firms. Many of these companies are small. They do not need a huge program. They need a clear, bounded one. The ranges below are typical, not quotes, and your real number depends on your environment.
What Drives the Price Most
Three things move your cost more than anything else. The first is your required CMMC level, which depends on the kind of government information you handle. The second is how many people, computers, servers and cloud accounts touch that information. The third is how much of your current setup already meets the requirements.
Company size matters less than you would expect. A 15-person firm with data scattered across laptops, personal email and old file servers can cost more to fix than a 60-person firm with one clean cloud environment. Tidy systems are cheaper to certify.
- Required CMMC level and contract type
- Number of users who handle controlled information
- Number of systems, servers and cloud services in scope
- Current state of your security controls
- Whether you already have written policies
A scoping worksheet that lists every system touching controlled data is the cheapest document you will ever produce for this project.
The Main Cost Categories
Think of the budget as a short list of line items. Some are one-time. Some repeat every year. The table below shows typical ranges for a small supplier in San Diego with roughly 10 to 50 people. Treat these as planning numbers, not offers.
| Cost Item | Typical Range | One-Time or Yearly |
|---|---|---|
| Gap assessment | $5,000 to $20,000 | One-time, repeat as needed |
| Policy & documentation writing | $5,000 to $25,000 | One-time, yearly review |
| Technical remediation labor | $10,000 to $75,000+ | Mostly one-time |
| Tools & licenses | $5,000 to $40,000 | Yearly |
| Third-party assessment | $20,000 to $100,000+ | Every three years |
| Ongoing monitoring & upkeep | $10,000 to $60,000 | Yearly |
Remediation is the line that surprises people. If your network needs rebuilding, if email needs moving to a compliant environment, or if staff need managed devices, the labor adds up fast.
Starting With a Gap Assessment
A gap assessment compares what you have today against what the requirements ask for. It produces a list of missing controls and a plan to close them. It is the least expensive way to find out how big the job is.
Skip it and you risk buying tools you do not need or missing things that will fail the real assessment. A good assessment also helps you shrink the scope, which lowers every cost that comes after.
What a Useful Assessment Delivers
- A diagram of where controlled information lives
- A list of controls that pass, partly pass and fail
- A ranked fix list with rough cost for each item
- A realistic timeline tied to your contract dates
Most gap assessments for a small office take one to three weeks from kickoff to written report.
Fixing the Gaps: Where Most of the Money Goes
Remediation covers the real changes to your environment. Typical work includes multi-factor sign-in, encrypted laptops, managed patching, logging, secure email, access controls and a protected place to store controlled files. Each one is small. Together they form most of your bill.
Support from CMMC compliance services can bundle this work and keep it matched to what an assessor will check. Doing it piece by piece with different vendors often costs more and leaves gaps between the pieces.
- Scope first. Decide which systems truly need to be in the protected area.
- Fix identity. Turn on strong sign-in and clean up accounts.
- Secure devices. Encrypt, patch and manage every laptop and workstation in scope.
- Protect data. Move controlled files to one approved location.
- Document it. Write down how each control works in your office.
Separating controlled data into its own protected area often costs less than hardening the entire company network.
Tools, Licenses & Hosting
Software and cloud costs are a yearly line, so they matter more over time than the first invoice suggests. You may need upgraded Microsoft licensing, endpoint protection, logging, backup and a secure file environment. Some suppliers choose a separate protected enclave for controlled data instead of upgrading everything.
| Approach | Upfront Cost | Yearly Cost | Best Fit |
|---|---|---|---|
| Upgrade your current environment | Higher | Moderate | Larger teams with most staff handling controlled data |
| Protected enclave for a few users | Lower | Moderate | Small teams where only a few people touch controlled data |
| Hybrid with Giga San Diego managing both | Moderate | Predictable monthly | Mixed teams that want one accountable provider |
Ask every vendor to show license costs per user per month. It makes comparing options much easier.
The Formal Assessment Fee
At certain levels, an outside assessor must verify your controls. Their fee depends on your size, scope and level. Prices vary widely, and assessors have limited capacity, so scheduling can add delay. Book early once you are close to ready.
Passing on the first attempt saves real money. A failed or incomplete review can mean re-testing fees and lost bid opportunities. This is why many owners pay for a practice review before the real one.
Also ask what the fee covers. Some quotes include a pre-visit, some charge separately for follow-up questions, and some exclude travel if your team works across multiple San Diego sites.
Organized evidence, with each control tied to a screenshot or policy page, shortens assessor time and the fee that goes with it.
Hidden & Ongoing Costs
Passing is not the finish line. You must keep the controls working. That means patching, log review, access reviews, staff training and yearly policy updates. Someone has to do this work, either your staff or an outside team.
Related frameworks overlap with this work. If you also handle patient data, HIPAA consulting may share many controls. If customers ask for audit reports, SOC 2 compliance consulting covers similar ground. If you take card payments, PCI compliance services adds a few more requirements. Planning these together avoids paying twice for the same control.
- Staff time pulled away from billable work
- Employee training and testing
- Replacing aging hardware that cannot meet requirements
- Yearly policy and control reviews
- Re-assessment when your scope changes
Ways to Keep the Budget Under Control
The best savings come before you spend. Narrow your scope, fix the easy gaps first and avoid buying a tool before you know the requirement it covers.
- Limit who touches controlled data. Fewer users and systems means fewer controls to prove.
- Reuse what you own. Many controls can be met with licenses you already pay for.
- Fix in phases. Spread costs across quarters, ordered by contract deadlines.
- Get written quotes. Ask for fixed prices on each phase, not open hourly work.
- Plan upkeep early. A flat monthly fee is easier to budget than surprise projects.
Owners who follow these steps often finish with a smaller bill and a cleaner network than they started with.
CMMC cost is not one number. It is a set of line items you can measure, shrink and schedule. Owners who scope tightly, fix the highest-risk gaps first and plan for yearly upkeep tend to spend less and feel calmer about the process. Owners who buy tools first usually pay twice.
A good next step is small. Get a free IT assessment so you know where your systems stand today. You will leave with a list of gaps, a rough price for each and a timeline tied to your contract dates. No pressure to commit, just a clear picture you can budget around.
FAQs
How much does CMMC certification cost for a small San Diego business?
Most small suppliers typically spend from the low tens of thousands to well over $100,000 across assessment, fixes, tools and the formal review. Your level, scope and current setup decide where you land. A gap assessment gives you a real estimate tied to your systems.
Is the assessment fee the biggest cost?
Usually not. Remediation labor and yearly tools often cost more than the assessment itself. Many owners budget only for the review and are surprised later. Plan for fixes, licenses and upkeep from the start.
Can I reduce cost by limiting scope?
Yes. Keeping controlled information in one protected area means fewer users and systems to secure and prove. A smaller scope can lower remediation, licensing and assessment effort. Define scope carefully before buying anything.
How long does it take to get ready?
Small suppliers with a decent starting point often need several months. Companies with scattered data or old equipment may need longer. Timelines also depend on assessor availability, so start early if a contract deadline is coming.
Do I need to pay for CMMC every year?
You pay for upkeep every year, including tools, monitoring, training and policy reviews. The formal assessment itself typically happens on a longer cycle. Budget for both so you stay compliant without scrambling.
Will my current IT provider handle it?
Some can, but many general IT providers lack compliance experience. Ask whether they have prepared other suppliers for assessment and whether they can produce the documentation an assessor expects. Ask for references.
Can I do CMMC preparation in-house?
If you have a skilled IT person with time, parts of it are possible. Most small firms lack the time and compliance knowledge. A mixed approach, with outside help on scoping and documentation, is common and often cheaper.
What happens if I fail the assessment?
You fix the findings and request another review, which can add fees and delay. Missing a deadline can cost you contract work. A practice review beforehand lowers the chance of a failed attempt.
Does CMMC cost more than other frameworks?
It often costs more than basic security programs because the requirements are detailed and evidence is carefully checked. Overlap with other frameworks can reduce duplicate work if you plan them together.
How do I get an accurate quote?
Start with a gap assessment or scoping call. Share your contract requirements, headcount, systems and where controlled data lives. A written quote should list each phase, its price and what is not included.
