The primary benefit of using a VPN (Virtual Private Network) for personal and business data security is enhanced privacy and security over internet connections. VPNs create a secure, encrypted tunnel for data transmission, making it difficult for unauthorized users to intercept or access sensitive information. This is especially critical when using public Wi-Fi networks, as VPNs protect personal and business data from potential attacks. Additionally, VPNs can help users maintain anonymity online, bypass geographic restrictions, and safeguard location data, contributing to overall cyber resilience.
