This tool is developed by one of the biggest network security company in the world. It will let you verify the traffic that comes into your network and check if it is safe or not. Basically, it is your best friend when you want to see if some of the traffic on your WI-Fi network is dangerous for your devices or not.

PRTG will monitor your firewalls and all that they let through. Its SNMP and NetFlow sensors will immediately let you know if your firewall has a breach. All the unusual traffic is located through the program’s Packet Sniffing Sensor. Once something odd is “sniffed”, PRTG notifies you and proposes some actions to take as soon as possible. In case there are security holes in the network because of the WIndows Updates, PRTG let the administrator know and helps him find solutions so none of the network’s data remains exposed.

PRTG is also a great WI-Fi scanner and monitoring tool that you could use while overwatching your network’s traffic.

You can try this program for 30 days and you can go on the free (but limited) version after that or you can continue by upgrading to a pro plan.
