VPNs are very popular with businesses who want to secure private data while making it accessible remotely. However, they are also popular with private users, especially those who use torrents. The other reason VPNs are popular is because they spoof location as well. This enables users to bypass website content filters that use location as a filter. The user's IP address is replaced with one from the VPN. A VPN acts as a firewall on a computer. The firewall protects data on the computer, but a VPN protects sensitive and private data online.

VPNs secure and encrypt data to guarantee that both sent and received data is not intercepted or spied on by other parties.
