Zero Trust is not a single product. It is a security framework that treats every request as untrusted until verified. The maturity model defines stages for adopting it. Moving from theory to execution starts with a clear, enforceable onboarding process that sets the foundation.
Stage One: Define Access Boundaries
Identify all users, devices, and services. Map their relationships. No shortcuts. This inventory becomes the reference point for every policy you create.
Stage Two: Establish Strong Identity Verification
Require multi-factor authentication for all accounts. Integrate with identity providers that support modern standards like SAML and OpenID Connect. Verify each identity before granting any resource access.
Stage Three: Implement Least Privilege Policies
Assign minimal permissions required for each role. Remove broad access controls. Automate audits and revoke unused privileges. This reduces the attack surface inside your environment.
