A VPN is a secure connection between your computer and a server. All your Internet traffic and browsing data goes through that remote server. To the outside world, the anonymous server is doing the browsing, not you. ISPs, government agencies, hackers or anyone else can’t track your activity online.
When you connect to a VPN, you create a secure, encrypted tunnel between your computer and the VPN remote server. The data is essentially gibberish to anyone who intercepts it. Your ISP, government or hackers won’t know which websites you visit. And conversely, the websites you visit won’t know where you are. Typically, logging in to a VPN is as easy as entering a password and clicking a button on a VPN client or a web browser extension.
