The video introduces two leading VPN providers — NordVPN and ProtonVPN — comparing free and paid options, speed, and performance. It also demonstrates how to install and use VPN apps on both computers (Windows, Mac) and mobile devices (iOS, Android). Additionally, the creator shows how to use the SimilarWeb tool to compare VPN popularity and choose the most reliable service. Whether you’re looking to secure your data, browse anonymously, or access geo-blocked content, this guide helps you get started confidently in 2025.
