VPN, virtual private network, short for VPN, can help you establish a secure connection to the Internet. If so, the encrypted connection will transmit all your Internet activity, so that no one will see your online activity and what you are doing. In essence, a VPN provides more security and privacy for all your online activities.

To ensure that you only connect to websites protected by HTTPS, even if the data leaves the VPN, the data will continue to be encrypted. These sounds simple and may be redundant, but they have a profound impact on your privacy.

You can imagine: if your car leaves a lane, someone will follow you to see where you are going, how long you are going to stay, and you will come back again. They can even spy on your car and get to know you better. With VPN, you can drive you from your home into an underground tunnel, enter a closed parking lot, change to another car, and drive out. No one knows where you noticed you at first.
