Charles and his family are going on a cruise and want to know if his devices need to run through a VPN. Leo says there are some risks, but not as much on an iPad. Google has been pushing for https everywhere, meaning that his search activity is encrypted. But that's not stopping someone from using a Wi-Fi sniffer called a Pineapple or Wireshark to figure out what his access point name is. A wise thing to do would be to forget his home network before he goes. Another option is the Tiny Hardware Firewall. But he should remember, a VPN will slow him down.
