Im currently running what i would say is a "normal home set up". I have a router as my main incoming wifi as well as a extender which is a netgear night hawk.
I run all PC traffic though a paid for VPN.
I also have a smart home, thermostat, alexa, wireless sockets etc. I have been told that the smart home is easy to "hack" AKA some sitting outside gaining entry via the smart home device.
Ive been told i need something like this; Ubiquiti UniFi Security Gateway to secure my home.
Please bear in mind my technical knowledge is limited!
