The Continuous Threat Exposure Management Maturity Model (CTEMMM) is a reference-based maturity model designed to help organizations assess, understand, and improve their Continuous Threat Exposure Management (CTEM) capabilities.

CTEMMM provides a structured way to evaluate CTEM maturity across lifecycle phases, domains, and categories, enabling consistent assessment, prioritization, and improvement planning across organizations and industries.

---

Purpose

CTEMMM is intended to be:

• A shared reference model for CTEM maturity
• A neutral assessment framework usable across tools and vendors
• A foundation for maturity evaluation, gap analysis, and roadmap planning
• A common language for security, risk, and leadership discussions

The model is designed for use by enterprises, consultants, educators, researchers, and vendors.
