Jose is concerned about being snooped on when using public Wi-Fi. What can he do to protect himself? Leo says the first thing to do is turn on hard drive encryption. That will keep his data safe should his laptop get stolen. But for just being on a public Wi-Fi, VPNs can be beneficial. VPN stands for "Virtual Private Network," and all of the traffic that goes through it is encrypted. It's like a secure tunnel through the internet. Most web pages are encrypted now, though, so no one could see his activity on those sites anyway.
Max has Eset's security suite and when he goes onto public Wi-Fi, it shows he's invisible to other computers. Leo says that's a good thing because public Wi-Fi is visible to anyone. Eset is probably turning on the Firewall, but he doubts there's a VPN going on here. If it's secure, he'll see the URL start with "https://." There's a move to make all internet traffic encrypted. But until that time, Max will have to remember that when he's on public Wi-Fi, he's out in the open.

Stan is on the local village council and wants to set up free Wi-Fi at their local parks. He doesn't know where to start, though. Leo says what Stan wants is a WISP (Wireless Internet Service Provider). When cities do public Wi-Fi, they go to a company and contract with them to do it for free in exchange for advertising. So that may be an option.
Google has a program called Google Community Wi-Fi. Local companies would be better than larger corporations.
