Systems fail when identity is weak. The Identity Zero Trust Maturity Model exists to prevent that failure. It defines clear stages for building, measuring, and improving identity security until only verified users and devices can move inside your perimeter.
Zero Trust starts with identity because compromised accounts open every other door. The maturity model is not theory. It is a roadmap. It shows how to progress from fragmented access control to adaptive, context-aware enforcement based on risk signals in real time.
Stage 1: Initial
Identity verification is basic. Password reuse is common. MFA coverage is partial. Trust is implicit once inside the network. Attackers exploit this stage by moving laterally after a single credential theft.
Stage 2: Managed
Centralized identity providers govern access. MFA is applied broadly. Role-based access is defined, but enforcement is incomplete. Visibility improves, but gaps remain in privileged account management and session monitoring.
Stage 3: Defined
Every asset is mapped to identity controls. Strong MFA is mandatory. Conditional access applies device health, location, and behavior to decisions. Privileged identities rotate often. Logging is detailed and centralized. The blast radius of a breach shrinks.
