Hi, please provide some details 1/. OS 2/. Web browser and configuration 3/. UTM http proxy mode 4/. specific sites you tried to surf to that you expected not to be able to access.
if you are logged into a google/gmail account you can't enforce safe mode settings in regular transparent mode because regular transparent mode doesn't scan ssl/gmail/google enforce https/ssl when you are logged in. If you want to enforce this you need to turn on https scanning..read the help files for the proper procedure BEFORE you enable this. Also ssl scanning will break some things like windows updates and other sites.
