Zero Trust is a security strategy or philosophy based on the guiding principle of "never trust, always verify."13 It dictates that no user, device, or application—inside or outside the network—should be automatically trusted.

ZTNA (Zero Trust Network Access) is the core technology used to implement the access-control portion of the overall Zero Trust model. 

ZTNA replaces broad-access VPNs with granular, identity-aware, least-privilege access to specific applications.16 Essentially, Zero Trust is the comprehensive model that governs all security decisions (data, users, infrastructure); ZTNA is the primary technological solution for enforcing secure remote access within that model.
