For defense contractors, cybersecurity is more than an IT concern. It can affect how sensitive information is protected and whether an organization can meet applicable contract requirements.
The Cybersecurity Maturity Model Certification (CMMC) program establishes cybersecurity requirements for organizations within the Defense Industrial Base. In 2026, CMMC continues to evolve, making it important for contractors to understand how CMMC IT requirements relate to their technology environment.
While the planned implementation of CMMC Phase II has been suspended for further review, Phase I requirements remain in effect. Contractors can use this time to understand their systems, identify security gaps, and strengthen their overall cybersecurity posture.
What Is CMMC?
CMMC is a cybersecurity framework designed to help protect sensitive information handled throughout the Defense Industrial Base.
Depending on the organization and contract, this may include Federal Contract Information (FCI) or Controlled Unclassified Information (CUI).
CMMC includes three levels of cybersecurity requirements. Level 1 focuses on basic safeguarding of FCI, Level 2 incorporates requirements based on NIST SP 800-171 for protecting CUI, and Level 3 includes additional requirements for organizations facing more advanced threats.
The level that applies to an organization depends on factors such as the information it handles and its contractual requirements.
What Changed With CMMC in 2026?
CMMC implementation entered Phase I in November 2025. In July 2026, however, the Department announced the suspension of the planned Phase II requirements while the program undergoes further review.
The suspension does not eliminate existing cybersecurity obligations for defense contractors. Phase I self-assessment requirements remain in effect, and contractors may still need to demonstrate that applicable cybersecurity requirements are being met.
For organizations within the Defense Industrial Base, maintaining a secure IT environment remains important even as the CMMC program continues to evolve.
Why Your IT Environment Matters for CMMC
CMMC readiness goes beyond installing antivirus software or having a firewall.
The cybersecurity requirements associated with CMMC can affect the people, technology, processes, and systems that interact with protected information. This can include employee computers, servers, cloud services, email, networks, user accounts, remote access systems, backups, and security monitoring.
Contractors should understand where sensitive information is stored, who can access it, and which systems process or transmit it.
This is particularly important for organizations handling CUI, which may have more extensive cybersecurity requirements than organizations handling only FCI.
7 IT Areas Defense Contractors Should Review for CMMC Readiness
Understanding your current IT environment can help identify potential gaps before they become larger security or compliance concerns.
1. User Access and Permissions
Employees should have access only to the systems and information necessary for their responsibilities.
Organizations should regularly review user accounts, administrative privileges, inactive accounts, and access permissions. Old accounts or excessive privileges can create unnecessary security risks.
2. Multi-Factor Authentication
Passwords alone may not provide enough protection for critical systems and accounts.
Multi-factor authentication adds another layer of verification when users sign in. Contractors should understand where MFA is currently enabled and whether additional systems require stronger authentication.
3. Network Security
Firewalls, network configurations, wireless security, segmentation, and remote access controls all contribute to a secure IT environment.
Contractors should also understand which parts of their network interact with FCI or CUI so appropriate safeguards can be applied.
4. Patch and Vulnerability Management
Outdated software and systems can create vulnerabilities that attackers may exploit.
Organizations should have a consistent process for updating workstations, servers, network equipment, and other technology. Regular vulnerability reviews can also help identify weaknesses that need attention.
5. Data Protection and Backups
Contractors should understand where sensitive information is stored, how it is transmitted, and who can access it.
Reliable backups are also important for protecting business operations. Backup systems should be monitored and tested to confirm that information can be recovered when needed.
6. Logging and Security Monitoring
Security isn’t only about preventing an incident. Organizations also need visibility into activity across their systems.
Logging and monitoring can help identify unusual behavior, unauthorized access attempts, and other potential security events before they become larger problems.
7. IT Documentation
Technology alone cannot address every cybersecurity requirement.
Accurate documentation of systems, policies, procedures, and security practices can help organizations understand their environment and maintain consistent cybersecurity processes.
Should Defense Contractors Wait for CMMC Phase II?
The suspension of Phase II may provide additional time, but contractors should not view it as a reason to stop improving cybersecurity.
Phase I requirements remain in place, and protecting sensitive government information continues to be an important responsibility for organizations working within the Defense Industrial Base.
Strengthening access controls, authentication, patching, backups, monitoring, and other IT practices can also help protect against threats such as ransomware, phishing, account compromise, and data loss.
Rather than treating CMMC preparation as a one-time compliance project, contractors can use it as an opportunity to strengthen their overall IT environment.
How an IT Provider Can Help With CMMC Readiness
Understanding cybersecurity requirements is one challenge. Determining how those requirements relate to your specific technology environment can be another.
An experienced IT provider can help evaluate current systems, identify potential security gaps, improve cybersecurity controls, and establish more consistent IT practices.
This can include reviewing network infrastructure, user access, endpoint security, cloud environments, firewalls, backups, patch management, security monitoring, and IT documentation.
The goal is not simply to check boxes. A well-managed IT environment can help strengthen security while creating a better foundation for current and future cybersecurity requirements.
Prepare Your IT Environment for CMMC
CMMC may continue to evolve throughout 2026, but cybersecurity remains an important part of doing business within the Defense Industrial Base.
Defense contractors can use this time to understand their IT environments, determine where sensitive information resides, identify potential security gaps, and strengthen the systems that support their operations.
