I have been trying out ExpressVPN to connect to the internet. I have mostly used this at a coffee shop that I use regularly.
I see this question with answers:
Here the accepted answer says:
"Both traditional VPNs and VPN services are to protect against external visibility into the network. Neither of them will protect you from authorized administrators for the network you're on."
I am not sure that I completely understand how the traffic is visible to the network one is on. For example: does this refer to the traffic before or after it is encrypted?
Where does the encryption happen when you use a VPN with encryption like ExpressVPN?
For example, if I am using the WIFI at my coffee shop, is the coffee shop able to see my unencrypted traffic? (Maybe my confusion is not understanding how a "network" in general works).
