A VPN (Virtual Private Network) is a service that creates a secure and encrypted connection over a less secure network, such as the internet. It is used to protect data privacy, ensure secure remote access to a network, and conceal the user’s IP address and online activities.
The main purpose of a VPN is to provide a secure and private connection between the user’s device and the internet or another network. This helps protect sensitive data, maintain privacy, and prevent unauthorized access to the network.
The need to use a VPN arises from the desire to protect online privacy, secure sensitive information from cyber threats, bypass geo-restrictions, and access restricted content. VPNs are also used by businesses to enable secure remote access for employees working from different locations.
A VPN does not provide internet access by itself. Instead, it secures and encrypts the existing internet connection. To use a VPN, you must already have an internet connection from an Internet Service Provider (ISP).
