About the Illumio Legacy Windows VEN
This guide describes how to install and use the Legacy Windows VEN (LW-VEN) with the Illumio Core PCE to enforce security policies on computers running the Windows Server 2003 SP1 & SP2 or Windows Server 2008 SP1 & SP2 operating system.
The LW-VEN is a custom version of the standard Illumio VEN. Like standard VENs, the LW-VEN is a lightweight multi-process application with a minimal footprint that runs on a workload. The LW-VEN programs the native OS firewall that enforces the policy controls you've defined for your legacy Windows machines.
In addition to this guide, you can also refer to the VEN Installation and Upgrade Guide and the VEN Administration Guide for in depth information about working with standard Illumio VENs.
