How does a VPN enhance online privacy?

A VPN (Virtual Private Network) enhances online privacy primarily by encrypting data sent over the internet. This process involves transforming the data into a coded format that can only be read by authorized users. When you use a VPN, your internet traffic is routed through a secure server, making it difficult for anyone, including hackers, internet service providers, or even government entities, to intercept or read your information. This encryption process safeguards your sensitive data, such as personal details, login credentials, and financial information, while you browse the web or use online services.

Unlike speeding up internet connections, which can vary based on many factors including network conditions and server distances, or filtering unwanted ads and blocking access to certain websites, the key function of a VPN related to privacy is its encryption capability. These other features do not focus specifically on enhancing privacy. Filtering ads often improves user experience but does not secure data, while blocking access to websites might restrict what you can view online, but does not encrypt your data or provide privacy from surveillance. Thus, the primary benefit of a VPN in the context of enhancing online privacy comes from its data encryption capabilities.
