A VPN, or virtual private network, is a mechanism for creating a secure connection between a computing device and a computer network, or between two networks, using an insecure communication medium such as the public Internet. When you use a VPN, your device connects to a remote server owned by the VPN provider, creating a point-to-point tunnel that encrypts your personal data, masks your IP address, and lets you sidestep website blocks and firewalls on the internet.
Here are some key features of a VPN:
-
Encryption: A VPN creates an encrypted tunnel between your device and the wider internet, ensuring that nobody can intercept your data while its in transit.
-
Privacy: A VPN connection is private because through this connection, no one else can see your data or browsing activity.
-
Virtualization: A VPN is virtual because no physical cables are involved in the connection process.
VPNs are widely used in corporate environments to extend a corporate network through encrypted connections made over the Internet, allowing employees to work outside the office and still securely connect to the corporate network. VPNs are also used by individuals to protect their online privacy and security.
