This video provides a comprehensive explanation of the key differences between a Proxy and a VPN, two tools that are often confused but serve very different purposes. A VPN (Virtual Private Network) encrypts all of your internet traffic, protecting your privacy and preventing your ISP, government, or hackers from tracking your online activities. A Proxy, on the other hand, routes traffic through different IP addresses without encryption, making it ideal for web scraping, data collection, e-commerce, and managing multiple social media accounts. The video also explains how VPNs work at the system level while proxies operate at the app level, and it compares the speed, security, and usability of each. It covers both Residential and Datacenter Proxies, their pros and cons, and introduces Smartproxy as a reliable, high-performance provider. This guide helps users decide when to use a VPN for security and when to choose a Proxy for speed and multi-account efficiency — essential knowledge for 2025’s online privacy and business operations.
