A VPN router is a device that connects to the internet and allows multiple devices in a home or office to use a Virtual Private Network (VPN) simultaneously. By routing all internet traffic through the VPN, it helps protect users' privacy and security by encrypting their data and masking their IP addresses. Using a VPN router simplifies the process of connecting various devices, such as smartphones, tablets, and computers, to a VPN without needing to install software on each one. This is especially useful for users who want to maintain a secure connection while streaming content or browsing the web.
