A VPN (Virtual Private Network) protects user privacy online by encrypting internet traffic and masking the user’s IP address. This ensures that data transmitted between the device and the internet is secure and concealed from potential threats, such as hackers or government surveillance. By routing traffic through a secure server, a VPN enhances online anonymity, allowing users to access content without revealing their location or browsing habits. Moreover, VPNs can help circumvent regional restrictions and censorship, granting users greater freedom on the internet.
