It's not the https that you have to worry about (no more or less than at home)

You need to be worried about others getting into your computer and stealing your info. That's why you need a strong firewall on your puter

The only thing an ISP or anyone else can gain from what traffic is being directly sent to or from https://example.com is that you visited https://example.com . To reiterate it is very difficult to spoof a https site.

What they are stating there is a bit misleading, the traffic between their service and your computer may be encrypted but it certainly will not be encrypted for the data they are proxying from any http site. e.g. You login into city cata and your connection is secure to them but the connection from their servers to city data is not and the data such as your login credentials can still be read by a third party.


As far as the https connections go I don't how their service operates but there is two possibilities.

1. They are sending the traffic between https://example.com and your computer directly in which case the traffic is encrypted using the sites key. This cannot be read by the VPN. Any encryption between your computer and their service is redundant.

2. They are acting as the man in the middle. You connect to the VPN using their key, the traffic between your computer and their service is encrypted however it is then decrypted and then encrypted using the sites key for traffic between their service and the site.

If it's number two this is not secure because the VPN can read all that data.
