I came across this questions on the Sophos UTM (Astaro) forums today:

“Can anybody tell me how can I use profiles to configure access to sites and categories by time period”

I thought it was a good opportunity to create a quick video to show how to allow sites during specific times using Sophos UTM, as well as keep an eye on them using Fastvue Sophos Reporter.

I hope this helps anyone trying to do the same. If you have any questions, please let me know in the comments!
