The image you see to your right is a depiction of what your network looks like. As you can see, when you are not using a VPN there is a larger space where your traffic is not encrypted, thus open to prying eyes. This is where Surshark VPN can help you..
It is 100% legal to use a VPN. To your right you will see some flagged countries. It is not permitted to use a VPN in those countries, although it should be noted that many foreigners use a VPN when visiting or working in China, so that they have access to google, since in China, the google server is blocked, and you may have important emails, so this is something to consider.
