Sophos Central: Update Cache and a Message Relay how it works in your network

Overview

Sophos Update Cache allows devices to get their Sophos update from cache server in the network. This saves bandwidth because updates are downloaded only once, by the server

A Message Relay allows your devices to communicate all policy and reporting data via a central server. This can be used if you do not have internet facing devices, as all traffic will go via the Message Relay
