NSX-V is VMware’s network virtualization platform that
is completely integrated with vSphere. The NSX-V Firewall and the
Service Composer are key features of the NSX-V Manager. The NSX-V
firewall is a logical firewall that allows you to attach network
and security services to the virtual machines, and the Service Composer
allows you to group virtual machines and create policy to redirect
traffic to the VM-Series firewall (called the Palo Alto Networks
NGFW service on the NSX-V Manager).
