Episode 1389 (58:03)

George from Sterling, VA
Tiny Hardware Firewall

George is using a Tiny Hardware Firewall and he sees that it would let him customize the settings. Can it be made more secure? Leo says that the Tiny Hardware Firewall is pretty darn secure as is. Leo hasn't played with the configurations, but he wouldn't want to, either. He just uses it in default mode and he's completely safe.
