What is a zero-trust network?

A zero-trust network is a security model that eliminates the concept of a trusted network zone, in which network traffic is automatically assumed to be safe. This means that even trusted users and services are no longer provided access until they are authenticated and authorized. In this model, all incoming traffic is treated as untrustworthy, and all devices must authenticate before being granted access to protected resources. All data flows are monitored for suspicious activity and any malicious activities or threats are promptly identified and addressed.
