Uses Calico's own policy CRDs beyond the upstream Kubernetes API - GlobalNetworkPolicy, HostEndpoint, NetworkSet, policy tiers, and DNS-based egress rules - applied and audited with calicoctl. Use when a policy must span namespaces or protect the host itself, when egress has to be expressed by domain name, or when ordering policies into tiers.
