The Marketing4WiFi platform does not provide any content filtering, guest data logging or guest data capture functionality. This is because the platform is not in the data path of your WiFi Guests Internet traffic.
If you need some type of filtering or logging of your guests Internet traffic, we would recommend working with your hardware (AP/Controller/Network) partner. The hardware used to provide the Guest WiFi network is the best place to look, because all Guest traffic already passes through it.
