Definition
Zero Trust is a security model in which no user, device or system is trusted solely because of location or previous Authentication. Each access request is verified against applicable security policy.
Human Explanation
Zero Trust follows a simple idea: never trust by default; always verify.
Why it Matters
The model reduces Risk from compromised accounts, devices or infrastructure and supports protection of distributed working environments.
Conceptual Boundary
Zero Trust is not a single product or technology. It is a model for designing and managing security through several complementary mechanisms.
Practical Perspective
Zero Trust does not eliminate Trust. It limits implicit Trust and replaces it with continuous access verification.
