"The best VPNs can make your online life more private with software that's convenient and cheap - sometimes even free. While keeping your IP address invisible, you can use your VPN to explore streaming content from all over the world or (virtually) sneak into a sports event that's not available in your area."
"You may know that a VPN masks your device with a proxy server to make it look like you're somewhere else, and maybe even that encryption is involved. But finding any more details can mean running a gauntlet of misinformation. That's a shame, because the inner workings of a VPN aren't all that difficult to understand. You may not be able to build one yourself without a degree in computer science, but with a little work, you can understand exactly what it's doing"
Virtual private networks create a secure tunnel between a device and a remote server so network traffic is forwarded and encrypted, protecting privacy and masking the device's IP. Organizations originally used VPNs to let remote workers access closed networks and secure files; consumer-focused services have grown rapidly, with providers such as Proton VPN and ExpressVPN attracting many users. A typical VPN system has two components: a client application on the device and a server that forwards requests to destination services. Multiple VPN types exist for different needs. Understanding encryption, tunneling, server trust, logging policies, and performance helps when choosing and using a VPN.
