This article explains the importance of testing the efficacy of a Virtual Private Network (VPN) to ensure privacy and security when using the internet.
It provides a step-by-step guide on how to check the performance of a VPN.
The first step is to understand the role of a VPN, which is to route internet connections through a remote server and encrypt data to keep it secure.
Users should check their IP address by visiting a site such as WhatIsMyIP.com, noting down their real IP address, and then revisiting the site whilst their VPN is connected to ensure it has changed.
The article also advises testing for DNS leaks, which can expose users’ online activity to their Internet Service Provider (ISP), and testing for WebRTC leaks, which can expose an IP address through real-time browser communication.
