Zero Trust is a security model that operates on the principle of "never trust, always verify." This means that no user or device, whether inside or outside the network, is automatically trusted. Instead, every access request is thoroughly authenticated and authorized before granting access to resources. This approach helps organizations protect sensitive data by minimizing the risk of breaches. By continuously monitoring and validating user identities and device security, Zero Trust ensures that only the right people have access to the right information at the right time, enhancing overall cybersecurity.
