Compliance is no longer a “nice to have.” but a business imperative. Buyers, partners, and regulators now expect proof of strong security. Companies of all sizes feel this pressure as they try to protect data, win deals, and avoid expensive risks.
The global GRC software market is expected to reach about $21 billion in 2025, and may grow to nearly $38 billion by 2030. ISO 27001 is also rising fast, with over 70,000 certified organizations across 150 countries. Global ISO 27001 certifications nearly doubled in 2024, showing how quickly businesses are moving toward structured security.
But even with all this growth, most teams still struggle to answer one simple question: “How much will compliance actually cost us?” Some sources say a few thousand dollars. Others talk about six-figure budgets. This confusion makes planning hard, especially for small and growing businesses.
This guide cuts through the noise. You’ll learn the real cost drivers, the difference between CMMC and ISO 27001, and how to build a smart budget without wasting money. The goal is to help you stay secure, stay compliant, and stay ready for any audit.
Why Compliance Budgeting Matters and How These Frameworks Differ?
Compliance budgeting matters because modern buyers no longer trust promises. They want clear evidence that your security program is working. This means companies must invest in structured processes, documented controls, and formal assessments.
CMMC is built for companies working with the US Department of Defense or handling Controlled Unclassified Information (CUI). It is strict, prescriptive, and tied directly to contract eligibility. You cannot win certain federal contracts without meeting the required CMMC level.
- CMMC Level 1 covers basic cyber hygiene.
- CMMC Level 2 is aligned with NIST 800-171 and requires a third-party assessment.
ISO 27001, on the other hand, is a global security standard used by SaaS companies, fintech, IT services, and B2B vendors. It’s not tied to government contracts but is a huge trust signal in enterprise sales. Many large companies require ISO 27001 before signing long-term agreements.
Both frameworks require similar policies, controls, training, and monitoring, but their assessment processes differ. CMMC audits are deeper and more technical. ISO audits are structured and process-driven. Because of this, online cost estimates often sound like guesses.
A good compliance budget solves this confusion by breaking costs into clear buckets.
The 5 Budget Buckets Every Compliance Program Needs
Every compliance (CMMC or ISO 27001) journey has the same five building blocks. These buckets help you plan spending and avoid financial surprises.
Readiness and gap assessment
The first step is understanding where you stand. A comprehensive gap assessment will review your controls, check policies, identify missing requirements, and map your environment. A proper gap assessment sets the foundation and prevents wasted effort later. The gap assessment should consider both technical and non-technical controls.
Implementation, tooling, and remediation
The next step is implementing the proper tools and controls to close any identified gaps. This is usually the largest budget area.
It may include MFA and single sign-on, firewalls, endpoint detection and response (EDR), and log management or SIEM tools. Backup and recovery upgrades, access control clean-ups, and cloud configuration fixes are also common remediation areas.
This bucket covers both hard costs (tools) and soft costs (engineering time).
Audit and certification fees
Both CMMC and ISO 27001 require formal assessments. Your budget should include stage 1 and stage 2 audits for ISO 27001, surveillance audits in Years 2 and 3, and C3PAO assessments for CMMC Level 2. Recertification after 3 years is also required for both standards. Keep in mind that these fees vary by size, scope, and audit firm.
People Costs
You need the right people on your team to develop and implement a cybersecurity program. You may need to hire internal security, or IT leads, external consultants, and fractional vCISOs. Engineering time for remediation tasks is also a factor. For CMMC, you will need to have a certified assessor on staff or hire one from an accredited third-party organization. If you lack internal capacity, this bucket grows quickly.
Ongoing Monitoring and Training
Compliance is not a one-time event. You must maintain it. Continuous monitoring, log reviews, vendor reviews, risk assessments, annual employee security training, phishing simulations, and evidence updates are key components of ongoing compliance. These tasks require dedicated resources and should be built into the organization’s processes.
CMMC vs ISO 27001 Price Breakdown
Below are realistic cost expectations for small and mid-sized businesses.
What CMMC level 1 actually cost?
CMMC Level 1 is the basic level. It checks if your company has simple, everyday security in place. Because it only needs a self-assessment, the cost is much lower than Level 2.
Most companies spend money on things like:
- Basic security tools
- MFA and password rules
- Backups
- Cleaning up access and user accounts
- Simple documentation
For many small organizations, a self-assessment to meet CMMC 2.0 Level 1 can start at $5,000 to $10,000. Real-world “compliance readiness, basic hygiene, minimal tooling” budgets often stretch up to $15,000 for small orgs that already have some security foundations.
If your systems are already in good shape, it can even be on the lower end. Ongoing yearly costs are small because there is no third-party audit required.
What CMMC Level 2 actually cost?
CMMC Level 2 is a big step up. It follows all 110 controls from NIST 800-171 and requires a C3PAO (Certified Third-Party Assessment Organization) to perform a real audit.
Companies usually spend money on.
- Logging and SIEM tools
- Network and cloud fixes
- Security configuration updates
- Writing and updating policies
- Evidence collection
- C3PAO audit fees
- Engineering and IT time
- Continuous monitoring tools
The official audit alone often costs $35,000 to $75,000. When you add tools, fixes, and prep work, many small or mid-sized organizations spend $50,000 to $ 150,000 or more in their first year.
This higher cost is normal because Level 2 is meant for companies handling sensitive government data.
Full ISO 27001 cost range for SMBs
ISO 27001 is used all over the world by SaaS companies, tech firms, and service providers. Costs vary a lot depending on how big your company is and how ready you are.
Typical cost areas include:
- Designing your ISMS
- Writing policies and procedures
- Risk assessments
- Security tools
- Stage 1 and Stage 2 audits
- Annual surveillance audits
- Employee security training
- Ongoing monitoring
For small companies, the total can be $20,000 to $40,000. For mid-sized companies, especially those with more systems or multiple locations, the cost can be $50,000 to $200,000+.
Most organizations fall somewhere in the middle, depending on how complex their environment is.
How shared drivers push your budget up or down?
CMMC and ISO 27001 have different rules, but the same things affect their price.
- How many systems you include?
- Number of employees?
- Cloud vs on-prem systems?
- If you have old or outdated technology?
- How mature your security is today?
- If you use internal staff or outside consultants?
- Which tools you choose?
- How many locations you operate from?
A small company with one cloud environment and a small team will pay much less than a company with old servers, many users, and several offices.
Building a Smart Compliance Budget (That Doesn’t Blow Up)
Choosing the right framework based on revenue goals
The best way to decide which compliance framework to pursue is to look at where your company earns its money. Compliance is not just a security choice. It’s a revenue strategy.
If your customers are in defense or government, you need CMMC, especially Level 2. Without it, you cannot win DoD contracts or work as a subcontractor with companies that handle CUI.
ISO 27001 is often the best investment if you sell SaaS, fintech, IT services, or any B2B product. It helps you pass security reviews faster, close enterprise deals, and reduce technical security questionnaires.
Build a shared control baseline if you sell to both markets. Many ISO and CMMC controls overlap, so you can design one strong security foundation and use it for both certifications.
When in doubt, follow the money. Choose the framework that protects or unlocks the largest portion of your revenue.
Shrinking scope the right way
Your scope is the single biggest factor that decides your total cost. A large scope means more systems, more users, more controls, and more audit hours, all of which increase cost. A small scope keeps the project manageable.
Ways to shrink scope without hurting security:
- Limit the systems included in certification.
Only include the systems that truly store or process sensitive data. - Isolate CUI or sensitive environments.
A separate, locked-down environment reduces audit effort and complexity for CMMC. - Use cloud-first setups instead of on-premise.
Cloud environments are easier to secure and often cheaper to audit. - Avoid a full-company ISMS scope for ISO unless required.
Many companies certify only their product team or their cloud environment.
A smaller, cleaner scope leads to lower audit fees, fewer controls to manage, and less internal time spent on remediation.
Reusing evidence and controls across both standards
CMMC and ISO 27001 may look different on the surface, but they share a large amount of similar requirements. Many controls cover the same ideas like access control, asset tracking, logging, training, vendor security, and more.
This means you can reuse large parts of your work:
- One set of well-written policies can satisfy both ISO and CMMC.
- A single risk management process checks both boxes.
- Same vendors, same due diligence.
- MFA, least privilege, and role-based access apply across both frameworks.
- One inventory of hardware, software, and cloud systems works for both.
- Logs, screenshots, tickets, and reports can be reused for multiple audits.
Reusing controls and evidence saves time, reduces confusion, and cuts the cost of maintaining two separate compliance programs.
Using fractional experts and freelancers instead of big consultancies
Many companies assume they need a large consulting firm to manage compliance, but this often leads to high costs, slow timelines, and rigid project structures.
A more modern and budget-friendly option is to build a hybrid compliance team instead. This approach combines a fractional vCISO for high-level strategy, freelancers for policy writing and evidence preparation, and small specialist firms for focused tasks like penetration testing or targeted audits.
Day-to-day security work can be handled by internal staff, which keeps knowledge inside the company and reduces the need for expensive external support. This blended model is flexible, efficient, and far more affordable.
Most organizations that switch to this structure save 30% to 50% compared to using large consulting firms, without sacrificing quality or expertise.
Turning the plan into a predictable 3-year budget for leadership
Executives don’t want surprises. They want a clear, predictable path that shows when money is spent and why. Turning your compliance work into a three-year plan helps leadership see compliance as a steady investment.
A smart 3-year plan looks like this:
Year 1:
This is usually the most expensive year.
- Complete readiness assessments.
- Fix security gaps.
- Set up tools.
- Build your ISMS or NIST-aligned environment.
- Complete the certification or main audit.
Year 2:
Costs go down after Year 1, but still require steady work.
- Maintain controls and policies.
- Handle continuous monitoring.
- Complete the ISO surveillance audit.
- Update risk assessments.
- Improve weak areas found during Year 1.
Year 3:
- Costs increase slightly during recertification but stay predictable.
- Prepare for recertification or the next major audit.
- Refresh policies and evidence.
- Strengthen your security program.
- Optimize tooling and processes.
Costs increase slightly during recertification but stay predictable. This plan turns compliance into a stable operating expense.
Conclusion
Building a smart compliance budget isn’t just about cutting costs. It’s about investing in the right areas so your company stays secure, wins more deals, and avoids last-minute surprises.
Whether you pursue CMMC, ISO 27001, or both, the real advantage comes from planning early, shrinking scope, reusing work, and choosing the right support model. When you combine strong internal ownership with targeted external expertise, compliance becomes manageable, predictable, and far more affordable.
