A practical readiness sequence for identifying contract requirements, protecting sensitive information, documenting compliance, and addressing gaps before an opportunity reaches the proposal stage.

Key Takeaways:
- What CMMC requirements should contractors prioritize first?
- Who needs CMMC compliance?
- How should small contractors prepare before bidding?
If a promising department of defense (DoD) contract opportunity landed on your radar right now, could you capitalize on it?
Would your cybersecurity controls and documentation satisfy applicable Cybersecurity Maturity Model Certification (CMMC) compliance requirements?
CMMC readiness is not something you build at the last minute after the DoD sends out requests for proposals (RFPs). It requires alignment across people, systems, policies, evidence, vendors, and contract processes.
The whole process from when you start to getting certified can take up to 12 months. Therefore, early preparation is key.
This article covers all you need to know and do about CMMC compliance requirements long before that bidding opportunity arrives.

Current CMMC Status: What Contractors Should Know
On July 13, 2026, the DoD suspended Phase II third-party assessment requirements pending a broader program review that will help reduce bureaucracy and costs for small, innovative companies in the defense supply chain.
However, CMMC Level 1 and applicable CMMC Level 2 self-assessment requirements under Phase I remain firmly in place.
The underlying obligation to protect covered Federal Contract Information (FCI) and Controlled Unclassified Information (CUI) has not disappeared. So don’t postpone CMMC readiness.
Who Needs CMMC Compliance?
CMMC compliance requirements apply to contractors and subcontractors whose systems process, store, or transmit:
- Federal Contract Information (FCI): Any data your company creates or receives while performing a federal government contract that isn’t meant for public release.
- Controlled Unclassified Information (CUI): Any data that’s not classified, but is sensitive enough to cause real harm if lost or misused. This includes things like blueprints for military equipment, software source code for a government system, and even unpublished research tied to your defense contract.
Not every contractor needs the same CMMC level.
The appropriate CMMC compliance requirements for you will depend on:
- The specific defense agency you’re working with.
- Solicitation and contract clauses.
- The systems handling FCI and CUI.
- Your role in the defense supply chain.
Requirements flowed down by a prime contractor may also apply even if you don’t work directly with the DoD.
That said, let’s explore how you can build CMMC readiness.
8 Steps to CMMC Readiness
Step #1: Identify the Information a Contract Involves
Without understanding which information you’ll receive, create, access, or transmit, you can’t really determine what your compliance scope entails.
That’s why you must answer these questions first:
- Will the contract involve FCI, CUI, or both?
- Where will that information enter the business?
- Which employees need access?
- Which applications, devices, servers, and cloud platforms will handle it?
- Will subcontractors or outside vendors receive it?
- How will the information be shared with customers and partners?
- Where will it be backed up or archived?
“Many companies make the mistake of starting with the tools needed to secure the information, but it is essential to first identify systems, personnel, and processes that handle the sensitive data and the procedures used to protect it,” says Alan Heimlich, president and attorney at Heimlich Law, PC, who advises technology executives on security risk and legal compliance matters.
One thing to emphasize here is that you shouldn’t automatically scope the entire company. If covered information can be kept inside a smaller, well-controlled environment, that may reduce complexity and cost.
Similarly, avoid creating an overly narrow scope that inadvertently excludes connected systems, administrative tools, security services, or people with access.
Step #2: Determine the Required CMMC Level
Are you subject to CMMC level 1, 2, or 3?
- CMMC Level 1 applies if you handle FCI and currently involves an annual self-assessment against 15 requirements spelled out in the Federal Acquisition Regulation (FAR) 52.204-21.
- CMMC Level 2, on the other hand, is required to safeguard CUI. Under the current Phase I implementation, you are required to complete a self-assessment every three years and submit an annual affirmation against the 110 requirements in NIST SP 800-171 Revision 2.
- Finally, CMMC Level 3 applies to certain higher-priority programs and carries additional requirements and a government-led assessment.
Choose the applicable level based on the solicitation, information you’ll handle, and contract requirements, then proceed to the next step.
Step #3: Define the Assessment Boundary
Here, the goal is to identify the specific environment covered by your assessment.
That includes all applicable:
- Employee laptops and desktops.
- Servers and network equipment.
- Email and collaboration systems.
- Cloud applications.
- Backup systems.
- Security and monitoring tools.
- Remote-access systems.
- Administrative accounts.
- Offices and other physical locations.
- Employees, contractors, and vendors with access.
Be thorough because getting the scope wrong can create problems in either direction. You could make your environment unnecessarily large and expensive to secure, or you could leave out a system that actually has access to CUI.
Our advice: Reference the official CMMC scoping guidance for the right decision whenever in doubt about your CMMC scope.
Step #4: Compare Current Controls With the Requirements
Are your current controls enough to satisfy CMMC compliance requirements? That’s the next question you must answer.
Review how you:
- Control physical and remote access.
- Authenticate users.
- Management user accounts from when they are created up to deletion..
- Protect data, devices, and networks.
- Have configured systems.
- Deliver security updates.
- Log and monitor what’s happening in your environment.
- Backup and recover data.
- Handle security incidents.
- Manage vendors and cloud-service use.
What employee security practices currently exist? Don’t make any assumptions.
Once you know what’s in place, evaluate it against FAR 52.204-21 for CMMC Level 1 or the NIST 800 171 compliance checklist for CMMC Level 2.
Ask yourself:
- Have we met applicable requirements?
- Which system, controls, or process satisfies them?
- Can we prove it?
- Are there any gaps, and if they are, how do we close them?
Once you’ve answered those, you’re ready for the next step.
Step #5: Build the Documentation and Evidence
Implementing the technical safeguards prescribed in the FAR 52.204-21 and NIST 800 171 compliance checklists alone won’t ensure compliance.
You must also prove it and demonstrate that your business follows CMMC compliance requirements consistently.
“The most common vulnerability causing defense contractors to incur unplanned delays during CMMC assessment relates to documentation,” Heimlich explains.
“Even if a company does everything right, it should ensure that there are written policies, processes, and procedures and that relevant personnel have been trained to perform their tasks in accordance with the established rules.”
Here are examples of documentation you should maintain:
- A System Security Plan (SSP) explaining how your security controls work.
- Network and data-flow diagrams.
- A list of company devices and systems.
- Security policies and procedures.
- User access records.
- Employee security-training records.
- Incident-response procedures.
- Backup and recovery procedures.
- System configuration standards.
- Security and risk reviews.
- Vendor and subcontractor records.
- A Plan of Action and Milestones where permitted.
- Evidence showing that security controls actually work.
When building documentation, always ensure what you have in writing describes and reflects your actual environment as accurately as possible to avoid unnecessary compliance risks.
Step #6: Prioritize the Gaps That Can Block a Bid
So, what CMMC compliance requirements should you prioritize?
Here’s a practical sequence:
#1. Information Identification and Scope
Determine what information must be protected and where it moves.
#2. Access and Identity Controls
Confirm that only authorized individuals can access covered systems and information.
#3. System Configuration and Endpoint Security
Establish controlled, consistent configurations across devices, networks, and applications.
#4. Monitoring and Incident Response
Ensure the company can detect, investigate, report, and respond to security incidents.
#5. Backup and Recovery
Confirm that critical information can be restored and that backup environments are appropriately protected.
#6. Documentation and Evidence
Record how each requirement is satisfied and preserve evidence that the control is operating.
#7. Supplier and Cloud Dependencies
Confirm that subcontractors, service providers, and hosted platforms support the contract’s security obligations.
The exact order may change once you complete your gap assessment. The important thing is to prioritize the issues that could create the biggest compliance or contract problem.
Step #7: Address Cloud Providers and Subcontractors
Your CMMC responsibilities don’t stop at the edge of your internal network.
Some DoD contract clauses require contractors to flow the appropriate level to subcontractors and confirm compliance before subcontract award.
For instance, DFARS 252.204-7012 stipulates that any cloud provider that stores, processes, or transmits CUI or FCI for defense contractors must meet the security requirements that apply to that information, along with applicable incident-reporting and forensic-support obligations.
Therefore, always review who among your third-party partners will have access to covered defense information, what requirements must flow down, and ensure they have the required status before bidding.
Step #8: Complete Assessments, SPRS Entries, and Affirmations
Finally, don’t wait until you’re submitting a proposal to figure out whether your assessment records are current.
Depending on the contract you’re bidding for, you may need to complete an affirmation of continuous compliance on top of conducting the CMMC Phase I self-assessment and recording your current Supplier Performance Risk System (SPRS) scores to be eligible for an award.
So, always ensure those are sorted long before submitting your bid.
Frequently Asked Questions About CMMC Compliance Requirements
1. Who needs CMMC compliance?
Defense contractors and subcontractors may need CMMC when their contracts involve FCI or CUI and include the applicable CMMC requirements. The required level depends on the solicitation, information type, and systems used to perform the work.
2. What CMMC requirements should contractors prioritize first?
Start by identifying the protected information, confirming the required level, defining the system boundary, and evaluating access controls, system security, incident response, backups, and documentation.
3. Is CMMC required before submitting a bid?
The precise timing depends on the solicitation. However, required status and affirmation may need to be current in SPRS before contract award, making last-minute preparation extremely risky.
4. Is NIST 800-171 the same as CMMC?
No. NIST SP 800-171 provides security requirements for protecting CUI, while CMMC provides an assessment and verification framework tied to defense contracts.
5. Can a contractor use a POA&M for missing requirements?
Some Level 2 deficiencies may be eligible for a conditional status and POA&M, but not every requirement can necessarily be deferred. Conditional items must be closed within the applicable period to achieve final status.
6. Does CMMC apply to subcontractors?
It can. Prime contractors may need to flow applicable requirements down when subcontractor systems will process, store, or transmit FCI or CUI.
Build Readiness Before the Opportunity Arrives
CMMC readiness is about more than passing an assessment. You need a controlled environment, accurate documentation, trained employees, well-managed processes, current records, and evidence that security requirements are operating consistently.
