A Super Node is a machine running a specially configured Endpoint Security Client that also consists of server-like and proxy-like capabilities, and which listens on port 4434 by default. Super Node is a light-weight proxy (based on NGNIX) that allows admins to reduce their bandwidth consumption and enable offline updates, where only the Super Node needs connectivity to the update servers.

Note - Super Node is not suitable for offline environments. Endpoint Security clients must be online and connected to the Harmony Endpoint Management server.
