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.

Larry went to NAB and saw the SONY Crystal LED (CLED) video wall - 18x32' 8K display. This is likely going to be a technology for billboards, video walls, movie theaters, and other hugely expensive applications.
What's a good, secure VPN? Leo recommends Tiny Hardware Firewall's Blackhole VPN. They don't log anything, nor do they report stuff.
Joe wants to know about the Tiny Hardware Firewall. Leo says it's a clever solution for those who want to use open Wi-Fi hotspots safely. Tiny Hardware Firewall will give him an additional layer of protection by encrypting all of his Wi-Fi traffic with a virtual private network. Leo adds that it also adds another layer called the Black Hole Cloud service which gives users their own cloud server. This makes it lightning fast. The Tiny Hardware Firewall is about $35, plus a fee for their VPN, which could be about $100 a year.
Russell has an iPhone SE and was using an app called Tether to use his cell phone as an internet hotspot. It doesn't work anymore, though. Leo says that it's been replaced by the hotspot feature in the phone, but his provider may not support it or may charge him a monthly fee to use it. Some carriers don't charge for it at all, like T-Mobile. But resellers, like Boost don't support it because the major carrier they work with doesn't. Will a VPN fix it? Leo says not for hotspotting, but a VPN will work for keeping his internet access encrypted and secure in public Wi-Fi hotspots.
Darrell worries that his laptop isn't safe on a public WiFi hotspot. Leo says that the reality is he does broadcast his web traffic via radio and it can be sniffed. But these days, most sites are encrypted and secure. If he's worried, using a VPN is a good idea. Leo likes Tiny Hardware Firewall.
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.
David wants to know if he can use a VPN on his tablet. Leo says that TunnelBear is a good one to look at. Leo uses Hotspot VPN with a hardware dongle called the Tiny Hardware Firewall that he can plug into the tablet and it creates a Wi-Fi access point that he surfs through. It's secure and easy to use.
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.
Frederick uses an open access port with his iPhone but it always asks him to sign in. Leo says that's called a captive portal, which is done when using a hotspot. He needs to activate the portal. He should point his browser to 220.127.116.11. Or he can choose to "forget" the Wi-Fi access point. That will reset it and then he can sign back in. Leo actually recommends getting a travel router like the Tiny Hardware Firewall to protect him.
