On Chit Chat Across the Pond #814, Adam Engst and I discussed the results of a VPN survey he conducted with the TidBITS subscribers. From there, we got into a discussion where Adam challenged the common wisdom that we need a VPN when we're on public WiFi networks. We got a bit mired in some of the discussion, where we almost had enough knowledge to explain our positions.

Networking is a topic on which Bart has a depth of knowledge, and he's here to clarify some of the things we talked about.

The recording you're about to hear was created for the Security Bits segment on NosillaCast #1048, but I felt it was important for the Chit Chat Across the Pond audience to hear it as a follow-up to our discussion with Adam.
