The concept of "zero trust" in cybersecurity refers to a security framework that operates on the principle of “never trust, always verify.” In this model, no user or device is automatically trusted based on their location—whether inside or outside the organization’s network. Instead, continuous authentication and validation of identity are required before granting access to resources. This approach helps mitigate breaches, reduces insider threats, and strengthens an organization’s overall security posture by enforcing strict access controls and monitoring.
