But VPNs also serve to hide your IP address, replacing the address logged on servers with one in a completely different location - even a different country. Fundamentally, most VPNs (virtual private networks) provide two services: They encrypt your data between two points and they hide the IP address (from which a general location can be derived) where you're located.įor those traveling or out and about, the first function is critical because most Wi-Fi available publicly is unencrypted - so anyone on the network can see what you were sending. To find the best VPN service for your personal needs, you'll need to compare brands, prices, features, and more. If you see inaccuracies in our content, please report the mistake via this form.
