What kind of Internet security system are you guys running to protect your network and your Internet of things?. I'm about to update my Wi-Fi router and was wondering if I need to add anything or do something special to make it really secure. Just letting you know, I do have one of those Cujo firewall protection devices. I don't know if anybody's ever used one of those or something similar? I'm going to upgrade my Wi-Fi router to the Asus RT AX3000 that's WIFI 6. Thank you
