How proxy servers actually work, and why they're so valuable
Briefly

Proxy servers function as intermediaries between users and the internet, allowing anonymity by masking the user's IP address. While often confused with VPNs, proxy servers differ in that they do not encrypt the data transferred between the user and the server. This article discusses how proxy servers work, their various types, and their applications in providing privacy online. It also emphasizes the VPN's additional security layer through encryption, making it more suitable for users seeking a higher degree of data protection.
A proxy server sits between your computer and a remote computer, acting on behalf of your machine and providing IP address anonymity during transactions.
While both proxies and VPNs obfuscate your IP address, VPNs add encryption, protecting data from hackers, ISPs, or government surveillance, especially on public Wi-Fi.
