Virtual Private Network (VPN) is a technology that enables a secure connection over a public or shared network such as the Internet. It allows a private network to be extended across the public network, allowing users to securely and privately access the network from anywhere in the world.
VPN works by creating an encrypted virtual tunnel between the user’s computer and the private network. All data sent over the public network is encrypted and sent through the tunnel, thus providing privacy and security. The encryption also prevents any third-party from intercepting or viewing the data sent.
VPNs are commonly used by organizations to protect sensitive data, such as financial records, emails, and employee data. Because of this, they are often used by large companies, government agencies, and universities. They also provide a secure connection for remote users or employees who need to access the company’s network. In addition, VPNs are widely used by individuals who want to access services such as VoIP, streaming media, file sharing, or online gaming from a public network while still ensuring their online activity is secure.
Overall, Virtual Private Networks provide an essential level of security when using the Internet and ensure that data is secure, private, and properly encrypted. VPNs also offer a way to securely access services and applications that are not available in a user’s local area.
