Internet anonymity and security technologies are discussed using examples of proxy servers and VPN (Virtual Private Network). A VPN creates a secure connection between the user's device and a remote server, encrypting traffic to prevent interception. This ensures hiding the real IP address of the user, bypassing blocks, and protection when using unencrypted networks such as public Wi-Fi.
A proxy server acts as an intermediary between the user and internet resources. It redirects requests to remote servers, replaces the real IP address for anonymity and bypassing blocks but does not encrypt traffic. A proxy can filter traffic based on specified rules.
The choice of technology depends on the user's goals and required security level. For protecting data when working with confidential information, banking services, and cloud storage, using a VPN is preferable.
