A Virtual Private Network (VPN) is specifically designed to allow for secure connections for remote users accessing a corporate network. It creates a private, encrypted tunnel over the public internet, ensuring that data transmitted between the remote user and the corporate network stays confidential and safe from eavesdropping or interception. This is particularly important for protecting sensitive company data and ensuring that only authenticated users can enter the network, thereby enhancing overall network security.

In contrast, while a firewall serves as a barrier that controls traffic based on predetermined security rules, it does not establish secure connections for remote users. An Intrusion Detection System (IDS) monitors network traffic for suspicious activity but does not facilitate secure remote access. Similarly, a proxy server acts as an intermediary for requests from clients seeking resources from other servers but does not inherently provide the secure connection functionality that a VPN offers. Thus, the VPN stands out as the appropriate solution for securely connecting remote users to a corporate network.
