Thank you for your question. I have done testing and found that Google Hangouts will work unless the user is in Sleep mode. I will be raising a ticket to see if it can have it correctly classified as a Social App so it can be blocked when needed.
Unfortunately, Google Hangouts works across key Google search domains. This means we cannot block Hangouts without blocking Google, which would make the internet basically unusable.
This means, Hangouts can only be blocked during sleep.
Thank you for the feedback. I will get this tested.
Hi Damian, Are you working on a way to block google hangouts without blocking google?
At this point in time, we cannot differentiate between google traffic and hangouts traffic. It may be something we will be able to do in the future, but at this time we cannot.
