Here’s how a VPN works for you, the user. You start the VPN client (software) from your VPN service. This software encrypts your data, even before your Internet Service Provider or the coffee shop WiFi provider sees it. The data then goes to the VPN, and from the VPN server to your online destination — anything from your bank website to a video sharing website to a search engine. The online destination sees your data as coming from the VPN server and its location, and not from your computer and your location.
When you use a VPN service, your data is encrypted (because you’re using their app), goes in encrypted form to your ISP then to the VPN server. The VPN server is the third party that connects to the web on your behalf. This solves the privacy and security problem for us in a couple of ways:
In a word, yes. But not always.
First off, VPN as a concept is somewhat new in “legal years,” so not all jurisdictions have managed to keep up. This means that the rules are murky and can be interpreted in many ways.
In overall, VPNs seem to be okay to use in most countries, especially in the US, Canada, the UK, the rest of Western Europe. (Important! What matters here is your physical location when using the VPN.)
Generally, VPNs are often not okay in China, Turkey, Iraq, United Arab Emirates, Belarus, Oman, Russia, Iran, North Korea, and Turkmenistan.
