Is smartphone tethering secure?

Episode 1360 (1:00:26)

David from El Segundo, CA
Tiny Hardware Firewall

David tethers his computer through his mobile device, but he's wondering if it's secure. Leo says it's probably more secure because cell phones are encrypted now. Using the Wi-Fi through his phone is a different matter, if he's at a public hotspot. At that point, his traffic is out in the clear and easily grabbed. If he's going to use a hotspot, Leo advises using the Tiny Hardware Firewall and a VPN. The Tiny Hardware Firewall is like a router that then connects to his phone. It's really good, but it can slow things down a bit.
