What term is used to refer to a device like a laptop, desktop, or mobile device in a zero-trust design?

In a zero-trust architecture, a laptop, desktop, or mobile device is referred to as a subject. Subjects like users, applications, or devices are not trusted by default. The system is also likely a policy enforcement point, not a policy application point, and will run a zero-trust client application that will interface with the zero-trust framework to determine if the system is secure as part of authentication and authorization processes.
