VPN or Virtual Private Network is a method used to increase the security and privacy of public and private networks, such as Wi-Fi and internet connection. VPNs are most often used by companies to protect sensitive data. However, using a personal VPN is becoming increasingly popular as more interactions that were previously face-to-face transition to the Internet. VPN protection increases as the user's IP address is replaced with one of the providers VPN. This method allows subscribers to reach IP address from any gateway city the VPN service provides.
