Virtual private network (VPN) is a technology that creates a secure and encrypted connection over a less secure network, such as the internet. It allows users to send and receive data as if their devices were directly connected to a private network, ensuring privacy and security. VPNs are commonly used to protect sensitive information, maintain anonymity, and bypass geographic restrictions by masking the user’s IP address. They are essential for safeguarding data in remote access scenarios, enhancing security for online activities, and ensuring confidential communication.
