Traditional security models often assume that users, devices, and systems operating within a network can be trusted by default. Modern organizations require a more proactive approach to security as users, applications, and data become increasingly distributed across cloud, hybrid, and remote environments. 

Zero Trust is built on the principle of continuous verification, ensuring that access is granted based on identity, context, and authorization rather than location alone. This approach helps organizations strengthen security, reduce risk, and improve protection against evolving cyber threats.
