In a vDefend NDR campaign, "hosts" refers to which of the following?

Within the VMware vDefend Network Detection and Response (NDR) UI and alerting systems, the term "hosts" is used from a cybersecurity perspective, not an infrastructure perspective. It refers directly to the network endpoints or virtual machines—specifically, your Workloads —that are participating in the analyzed traffic. It does not refer to the underlying physical hypervisors (like vSphere ESXi hosts or VCF nodes) that run the compute layer. NDR monitors these workload "hosts" to correlate suspicious activities into broader threat campaigns.
