Bitdefender Box 2 is perfect for a smart home. A home network is only as secure as the weakest item attached to it (robot vacuums, for example). It allows you to control all items attached to your Wi-Fi and review them. I no longer have a smart home with tons of network-connected devices. It is a subscription service, but adding this to your home doesn't require you to change your Wi-Fi and password because it can be set up to clone your existing connection it if you want.
