Episode summary

Firewalls in buildings stop fire from spreading.

Firewalls on computers do something similar: they stop malware from spreading.

Your router has a firewall that blocks threats from the internet before they reach your home network.

But what if the malware is already inside your network?

For that, you need a firewall on each of your computers.

These are especially vital for laptops, which often connect to public wifi.

And here’s the secret weapon almost nobody talks about: outbound firewalls.

They’re a unique and powerful extra layer of protection - and wildly underrated.

Call to action

Please verify that the firewall is turned on for each computer in your home.
