VPN explained… A Thread

A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the Internet. VPNs are commonly used to protect sensitive data, enhance online privacy, and allow users to access region-restricted websites.

How VPNs Work:

When you connect to a VPN, your internet traffic is routed through a secure server operated by the VPN provider. This process masks your IP address and encrypts your online activities, making it difficult for hackers, government entities, and ISPs (Internet Service Providers) to monitor your actions. Here’s how it works:

• Encryption: VPNs use encryption protocols (like OpenVPN, L2TP/IPsec, or IKEv2) to secure the data being transmitted. This means that even if someone intercepts the data, they cannot read it without the encryption key.

• Tunneling: VPNs create a "tunnel" through which your data travels, ensuring it is shielded from outside interference. The tunnel can be established using various protocols that differ in security levels and speed.
