Central Endpoint Updates Caching to XG

Question

Hi 
 Looking to migrate on prem clients to Central and have an XG as the gateway - if I enable the `Always cache Sophos endpoint updates` on the XG will the central clients use this? If so how will I know they are getting the updates from XG? (is there a report/function to view?) 
 Bandwidth is of concern with an entire organisation working remotely so I would like to be sure if I do migrate these on-prem clients to Central the pipe is not going to get saturated with updates. 
 Any help appreciated 
 Regards Ed

Hi Ed, 
 
 For your remote users - what type of VPN are you using? I am assuming it is a split tunnel - where traffic to your internal net is through the VPN but anything else goes out the direct ISP link the remote computer has. Is this correct? 
 If it is, each machine will reach out to Sophos Central on its own and update from there using the local ISP. 
 As others have said, an update cache in your main site (or one in each site if you have decent sized nodes) really helps with the bandwidth because the update cache pulls the updates from Central and then it is only local traffic (on your switch or switches) that distributes the data to the endpoints in the site. 
 There are a lot of options here and without more accurate data about what your specific deployment is it will be hard to give you good guidance. 
 
 If you have more questions, please post them.
