What is a VPN?

Definition and basic functionality of VPNs

A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a public or untrusted network, such as the internet. It enables users to establish a private network that extends across a public network, effectively allowing them to send and receive data as if their devices were directly connected to a private network.

The core functionality of a VPN lies in its ability to encrypt data transmitted between a user’s device and the destination server or website. Encryption involves encoding the data in such a way that it becomes unreadable to anyone who intercepts it without the decryption keys. By encrypting the data, VPNs add an extra layer of security, preventing unauthorized access and ensuring the confidentiality of sensitive information.

How VPNs work to secure internet connections

When a user connects to a VPN, their device creates a secure tunnel to the VPN server through which all internet traffic is routed. This tunnel encrypts the data, making it secure from eavesdropping and interception. The encrypted data is then transmitted from the user’s device to the VPN server and vice versa.

The VPN server acts as an intermediary between the user’s device and the internet. It relays the encrypted data to the intended destination, such as a website or online service, and retrieves the response. The response is then encrypted and sent back through the secure tunnel to the user’s device. This process ensures that all communication between the user and the internet is protected and remains confidential.
