What is a Virtual Private Network (VPN)?

by Paul Davies

Virtual Private Network (VPN)

A Virtual Private Network (VPN) is a technology that allows users to create a secure, encrypted connection over a less secure network, typically the internet.

A VPN tunnels the user’s internet traffic through an encrypted connection to a remote server, hiding the user’s IP address and ensuring that data transmitted between the user and the destination server remains confidential and secure. VPNs are commonly used to:

  • Protect Data: Encrypt data to prevent eavesdropping, especially on public Wi-Fi networks.
  • Bypass Geographical Restrictions: Access content that may be restricted based on the user’s physical location.
  • Maintain Privacy: Hide the user’s browsing activity from their ISP or other third parties. However, not all VPNs provide the same level of security, so it’s important to choose reputable services with strong encryption standards and a no-logging policy.
