Virtual private networks (VPNs) are facilitated by technologies that create secure and encrypted connections over the internet. VPNs allow users to securely send and receive data as if they were on a private network, protecting sensitive information from unauthorized access. This technology is essential for maintaining privacy, especially when using public Wi-Fi networks. Furthermore, VPNs can bypass geographic restrictions, enabling access to content from different regions. By encapsulating user data, VPNs enhance online security and promote safe internet usage practices.
