CMMC (Cybersecurity Maturity Model Certification) and CMMI (Capability Maturity Model Integration) are both frameworks that aim to improve the practices of organizations, but they focus on different aspects and are structured differently. Below is a comparison of CMMC levels 1 to 5 and CMMI levels 1 to 5:
Overview of CMMC Levels
CMMC is specifically designed for the defence sector, ensuring that contractors and subcontractors meet specific cybersecurity requirements to protect Controlled Unclassified Information (CUI). The CMMC framework consists of five maturity levels, each with a set of practices and processes.
CMMC Levels:
Level 1: Basic Cyber Hygiene
- Focus: Basic safeguarding measures.
- Practices: Implementing basic security practices such as using antivirus software, regularly updating systems, and providing security awareness training to personnel.
Level 2: Intermediate Cyber Hygiene
- Focus: Intermediate controls.
- Practices: A structured implementation of security measures, including documentation and management of cybersecurity practices and policies.
Level 3: Good Cyber Hygiene
- Focus: Protecting CUI.
- Practices: Comprehensive security practices aligned with NIST SP 800-171, including access controls, incident response, and risk management.
Level 4: Proactive
- Focus: Advanced security practices.
- Practices: Enhanced security measures, continuous monitoring, and proactive identification and mitigation of cybersecurity risks.
Level 5: Advanced/Progressive
- Focus: Cutting-edge capabilities.
- Practices: Continuous improvement and advanced security practices, including automated response and threat intelligence integration.
Overview of CMMI Levels
CMMI is a process improvement framework applicable across various industries, focusing on enhancing organisational capabilities and performance. CMMI also consists of five maturity levels, each representing a progression in process maturity.
CMMI Levels:
Level 1: Initial
- Focus: Ad-hoc processes.
- Characteristics: Processes are unpredictable and reactive; success depends on individual efforts rather than established processes.
Level 2: Managed
- Focus: Basic project management.
- Characteristics: Processes are planned, documented, and monitored; there is a focus on managing project performance and ensuring that commitments are met.
Level 3: Defined
- Focus: Standardized processes.
- Characteristics: Processes are well-defined and tailored to the organisation; there is a focus on process improvement and consistency across projects.
Level 4: Quantitatively Managed
- Focus: Data-driven management.
- Characteristics: Processes are controlled using statistical and quantitative techniques; performance is measured and managed quantitatively.
Level 5: Optimising
- Focus: Continuous process improvement.
- Characteristics: Focus on continuous improvement through innovative technologies and techniques; there is an emphasis on proactive process optimization.

Summary
While both CMMC and CMMI consist of five maturity levels, they differ significantly in their focus and objectives. CMMC is specifically tailored for cybersecurity in the defence sector, while CMMI is broader and applicable to various industries for process improvement. Understanding these frameworks and their respective levels can help organisations navigate compliance, enhance their practices, and improve overall performance.
