A VPN (Virtual Private Network) is used in corporate environments to create secure, encrypted connections between remote users and the company’s internal network. This technology allows employees to access sensitive information and resources from different locations while ensuring their data remains protected from eavesdropping or unauthorized access. By tunneling internet traffic through secure servers, a VPN can also mask users' IP addresses, enhancing privacy. Overall, a VPN streamlines remote work, facilitates secure communication, and safeguards corporate data against potential cyber threats.
