Which technology is used to securely connect remote users to a company network over the Internet?

The technology used to securely connect remote users to a company network over the Internet is a Virtual Private Network (VPN). VPNs create encrypted tunnels between the user's device and the company network, ensuring that data transferred over the Internet is protected from eavesdropping or interception. This encryption secures sensitive information and maintains privacy when accessing company resources remotely.

LAN (Local Area Network) refers to a network that connects devices in a limited geographical area, typically within a building, and is not designed for secure remote access. WAN (Wide Area Network) connects larger geographic areas and may include multiple LANs; however, it does not inherently provide secure remote access features, as it is primarily concerned with the interconnection of networks over large distances. Firewalls are security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules, but they do not create secure connections like a VPN does for remote users.
