The Cybersecurity and Infrastructure Security Agency Zero Trust Maturity Model (CISA ZTMM) is a strategic framework primarily intended for U.S. Federal Civilian Executive Branch agencies to help them develop and implement a zero trust architecture.
The purpose is to provide a standardized, achievable roadmap for shifting operations toward core zero trust principles. It requires organizations to structure their security around five core pillars (identity, devices, networks, applications and workloads, and data) and three supporting cross-cutting capabilities (visibility and analytics, automation and orchestration, and governance). Each pillar and capability is broken down into functions aligned to maturity levels. The goal is to move from traditional practices toward optimal security, with ongoing validation and strict least-privilege access across the organization.
