Home version for Mac sending out data?

Can I show you how Sophos Web Intellegence is hammering my iMac (Retina 5K, 27-inch, 2017) (High Sierra 10.13.4)

My Mac has been on for 28 hours now and Sophos Web Intellegence has sent 1.2Gbs  and received 1.2Gbs through the network. What kind of information sharing is this? 10-20Mbs is fine, but 1Gb and climing is extreme!

Also related to traffic hits - can we stop Virus updates happening at peak times please?

Hi Mark , 

The SophosWebIntelligence (SWI) is acting as a proxy for all your request so the data sent and received to the SWI will be counted as well. The diagnostics will also count internal communication between applications.

e.g. 

Website 1

say the website is 600KB , the browser would send say 10kb data for the request this request is gone through the SWI and goes to the web server.  The data received is 600KB by your PC will be processed through SWI i.e Received DATA is 600KB and forwarded to your browser which is sent from SWI which is SENT data i.e. 600KB . So SWI sent and receive will almost be the same as the browser communication.

Your actual internet usage would still remain 600KB not 1200KB.
