Hi,

 

you will have to check on the matching policy what exactly is logged on when your mobile is causing the traffic that gets allowed. I don't know how you are blocking (DNS, Web filter, application control or ISDB?) but would guess the mobiles are using a different site than the desktop versions. Typically, it is done because of a mobile optimization and FortiGate categories might either not know it or you haven't selected the respective mobile version.

For example YouTube:

https://m.youtube.com

https://www.youtube.com

One is the mobile variant, the other is the desktop.

 

Another thing to see is the inspection profile on the policy. The FortiGate must be able to read the traffic, if it cannot read it, but only see a few TLS certificate exchanges or IP addresses, then that is the only thing that can be acted upon and blocked.

 

Best regards,

 

Markus
