How VSX Works

Each Virtual System works as a Security Gateway, typically protecting a specified network. When packets arrive at the VSX Gateway, it sends traffic to the Virtual System protecting the destination network. The Virtual System inspects all traffic and allows or rejects it according to rules defined in the security policy.

In order to better understand how virtual networks work, it is important to compare physical network environments with their virtual (VSX) counterparts. While physical networks consist of many hardware components, VSX virtual networks reside on a single configurable VSX Gateway or cluster that defines and protects multiple independent networks, together with their virtual components.

Physical Network Topology

In a typical deployment with multiple Security Gateways, each protects a separate network. Each physical Security Gateway has interfaces to the perimeter router and to the network it protects.
