Federal contractors are increasingly subject to cybersecurity requirements designed to protect government information and systems especially if the contractor will handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI). However, not every federal contractor is subject to every cybersecurity framework. 

The requirements that apply to your organization depend on your contracts, the type of government information you handle, and the systems or services you provide. 

Comparing the Major Requirements 

The Practical Difference 

Being a federal contractor does not automatically mean an organization is subject to CMMC, NIST SP 800-171, FISMA, or FedRAMP. Applicability depends on the specific contract requirements and the nature of the information, systems, or services involved. 

• NIST SP 800-171: "We have CUI. What cybersecurity controls must we use to protect it?" 

  
  

• CMMC: "We are a DoD contractor subject to CMMC. How do we demonstrate that we meet the required cybersecurity level?" 

  
  

• FISMA: "We are operating a federal information system. How does the government manage and authorize its security?" 

  
  

• FedRAMP: "We provide a cloud service to the federal government. Has the cloud environment been appropriately assessed and authorized?" 

  
  

• NIST SP 800-53: "What security and privacy controls are used in the federal information-system authorization process?" 

  
  

Cost and Time Considerations 

Meeting federal cybersecurity requirements can require a significant investment of both money and internal resources. The actual cost varies substantially based on the organization's size, existing cybersecurity program, number of systems and users, amount of CUI handled, and whether significant technology or infrastructure changes are necessary. For perspective: 

• CMMC Level 2: Department of Defense estimates indicate approximately $37,000–$49,000 for a Level 2 self-assessment and approximately $105,000–$118,000 for a third-party certification assessment. These figures primarily represent assessment-related costs and should not be viewed as the total cost of implementing the required cybersecurity controls. 

  
  

• NIST SP 800-171: Federal estimates have placed assessment costs at approximately $25,000–$130,000, with remediation costs estimated at approximately $35,000–$115,000, depending on the organization's circumstances. 

  
  

• CMMC Level 2 implementation: Industry and government-industry data indicate that organizations with significant gaps may spend $100,000 or more on implementation, technology, remediation and related costs. Some organizations may require 6–12 months or longer to reach readiness. 

  
  

• FedRAMP: Costs can be substantially higher because FedRAMP involves authorization of an entire cloud service environment. Government studies have identified authorization costs ranging from tens of thousands of dollars to several hundred thousand dollars, with some cloud providers reporting infrastructure costs exceeding $1 million. 

  
  

These figures are provided for general planning purposes only. They are not quotes, required spending levels, or guarantees of the cost or time necessary for an individual organization to achieve compliance. The applicable contract requirements, existing security controls, system architecture and scope of the environment will significantly affect the actual cost and timeline.

Organizations considering a new federal contract or cybersecurity certification should evaluate these requirements early in the contracting process because implementation can require substantial IT resources, outside expertise, employee time, technology investments and ongoing maintenance. 

Can Cybersecurity Compliance Costs Be Included in a Proposal? 

Yes. Cybersecurity-related costs may generally be considered as part of a contractor's overall cost of doing business and proposal pricing, where appropriate.

However, including the costs in a proposal does not necessarily allow a contractor to defer compliance until after award. For requirements that are a condition of award, such as applicable CMMC requirements, the contractor may need to demonstrate the required status before receiving the contract.  

This can create a significant burden for small businesses because they may need to invest in cybersecurity technology, personnel, consultants, documentation and assessments before knowing whether they will win the contract. 

The same issue can arise with other federal cybersecurity requirements when compliance or authorization is required before contract performance. Before bidding, Contractors should 

• Review the solicitation and contract for specific cybersecurity requirements; 

  
  

• Determine whether compliance is a condition of award or a performance requirement; 

  
  

• Identify one-time implementation and recurring compliance costs; 

  
  

• Determine which systems and information are within scope; and 

  
  

• Consult contracts, accounting and cybersecurity professionals regarding appropriate treatment of those costs in the proposal. 

  
  

Bottom line: A contractor may be able to account for appropriate cybersecurity costs in its proposal, but pricing those costs into a bid does not substitute for meeting a required cybersecurity or authorization standard before award. 

Recent CMMC Developments and Small Business Impact 

There has been significant discussion regarding the cost, administrative burden and potential impact of federal cybersecurity requirements on small and midsize businesses. Most recently, on July 13, 2026, the Department of War suspended the planned Phase 2 expansion of the CMMC program.

The suspension followed concerns raised by the U.S. Small Business Administration and small-business stakeholders that the cost and administrative burden of CMMC could discourage smaller and nontraditional businesses from participating in the Defense Industrial Base. 

The Department has established a CMMC Reform Task Force to review the program and identify ways to reduce compliance costs and barriers for small and midsize businesses while maintaining appropriate protection of federal information.  

Government Cybersecurity Resources 

The following official government resources may help organizations better understand and evaluate their federal cybersecurity obligations: 

• NIST SP 800-171 Rev. 3 – Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations — Provides the security requirements for protecting CUI in nonfederal systems and organizations. 

  
  

• NIST SP 800-171A Rev. 3 – Assessing Security Requirements for CUI — Provides assessment procedures and methodology that organizations and assessors can use to evaluate implementation of the NIST SP 800-171 requirements. 

  
  

• NIST SP 1318 – SP 800-171 Rev. 3 Small Business Primer — A practical introduction designed to help small and medium-sized businesses understand and begin implementing the NIST SP 800-171 Rev. 3 requirements. It includes FAQs, implementation tips, examples and additional resources.

What Should Federal Contractors Do? 

Clients should review their current federal contracts and solicitations to determine whether they: 

• Handle Federal Contract Information (FCI) or Controlled Unclassified Information (CUI); 

  
  

• Perform work under a DoD contract; 

  
  

• Have CMMC requirements incorporated into a contract; 

  
  

• Operate systems on behalf of a federal agency; 

  
  

• Provide cloud services to federal agencies; or 

  
  

• Have specific NIST, FISMA, FedRAMP, or other cybersecurity requirements incorporated into their contracts. 

  
  

C2 Essentials’ Role 

C2 can assist clients with identifying HR-related considerations associated with applicable federal-contractor requirements. Cybersecurity compliance determinations—including whether an organization is subject to a particular cybersecurity framework or has satisfied its requirements—should be evaluated by the organization's IT, information-security, compliance, and/or legal professionals. 

Clients that are unsure whether a particular cybersecurity requirement applies to their organization should review the applicable contract provisions and consult with their cybersecurity or legal advisor.
