We are releasing a new policy setting to all customer on the w/c 2nd November, 'Track Network Connections'. This will be in the Advanced Settings section of the Threat Protection policy
We plan to enable this new feature gradually over four weeks; it will help our detection of malicious behavior by allowing our rules to monitor network flows. There is nothing you need to do for this enablement, however, if you wish to control its activation, you should disable the feature in policy. You can then control its activation as the next time it is set in policy, it will be enabled for devices which that policy applies to.
