Will a VPN keep my web traffic private?

Episode 1522 (22:47)

David from Anaheim, CA

David is thinking about installing a home VPN. Leo says he understands the security concerns, but he won't like using it for very long. It will really slow down his bandwidth. Leo recommends a service called CloudFlare. It changes his DNS to 1.1.1.1, and then masks his traffic so his ISP doesn't know where he's going. He can set it at the router level and he will protect every device in his house.
