What Is Zero Trust Security and How Does It Work?

Zero Trust is a security approach built around continuous verification. Instead of assuming anything inside the network is safe, it checks identity, device state, context, and access need before granting or maintaining trust.

In practice, that usually means stronger authentication, least-privilege access, segmentation, and monitoring that can respond when risk changes.

Zero Trust is not a single product. It is a model that helps organizations reduce the impact of stolen credentials, unmanaged devices, and excessive access permissions.
