A virtual private network (VPN) is a secure connection method used to access the internet privately. It works by routing your internet connection through a server operated by a VPN provider, masking your IP address and encrypting your data. This encryption protects your information from prying eyes, such as hackers or government surveillance, while ensuring your browsing remains private. VPNs allow users to bypass geo-restrictions on content, enabling access to blocked websites and services in certain regions. Overall, VPNs enhance online security and privacy, making them essential for individuals and businesses alike.
