Sophos Central Partner dashboard - find out which customer's dashbboard is client connected to

I've looked at this is the past:

1 option might be to create a policy marker, e.g. in the Global Exclusions for the accout:
https://cloud.sophos.com/manage/endpoint/config/settings/scanning-exclusions

Just create an entry to denote the account, for example, a non existent scheduled scanning exclusion, e.g.

z:\accountname1.

This will end up here:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Sophos Endpoint Defense\Scanning\Config
OnDemandExcludeFilePaths

You can use this to determine which account the EP belongs to.

The other option, is to use the CustomerID value under:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Sophos\AutoUpdate\

I think, from the partner portal, if you use the developer tools of the browser (F12), when you're on the list view of accounts, under the XHR, in the JSON response from the API, you can see the details of the accounts, one of the properties will be the customerid.  So it is possible to make the mapping, just a little more fiddly to get the data.
