Distributed Firewall
Stateful L2–L7 firewall enforced at the vNIC in the ESXi kernel — no traffic hairpin to a centralized appliance. Policy distributes to every host, so enforcement follows the workload. Supports VMs, containers, and physical workloads via bare-metal agents. vDefend 9.1.1 raised throughput to 22 Gbps per host on 25G NICs (+129%) and 75 Gbps on 100G NICs (+241%), scaling to 75 Tbps per VCF instance.
