David wants to know about Tunnel Bear. Leo says that Tunnel Bear is a virtual private network or VPN, which essentially burrows a digital secure tunnel in the internet. Is it secure enough to bank with or should he just trust "https"? Leo says both are very similar. The difference is that https activity cannot be seen by anyone, but they can see that he's been online. It can also be probed, whereas VPNs are tunnels that encrypt all of the traffic. no one could see anything. It's more security, but similar security. It's up to David. If he's on a hotspot, VPNs are the way to go.
