VPN stands for Virtual Private Network. It is a technology that creates a secure connection over the internet by encrypting data transmitted between a user's device and a remote server. VPNs enable users to access the internet privately and bypass geographical restrictions, enhancing online security and privacy. By masking a user’s IP address and routing traffic through a secure server, VPNs provide protection against eavesdropping and unauthorized access, making them essential for individuals and organizations concerned about data security.
