What does a clientless VPN facilitate?

A clientless VPN facilitates easy web-based access without requiring the installation of additional software on the user's device. This type of VPN is designed to allow users to connect securely to a corporate network through a standard web browser, which means they can access certain resources remotely without needing to manage or configure a separate VPN client application.

These solutions are particularly useful in scenarios where users may have restrictions on installing software due to organizational policies, or when accessing the network from devices like public computers or devices that do not support VPN client installations. By leveraging web-based interfaces, clientless VPNs provide a straightforward and flexible means for accessing applications and resources while maintaining security through encrypted connections.

The other options do not accurately reflect the primary function of a clientless VPN. For example, secure remote access via an application typically requires a client application to be installed, which is not the case with a clientless solution. Full control over network firewall settings is more related to network administration than to the functionality of a clientless VPN. Lastly, direct access to a file server does not inherently define a clientless VPN; it focuses more on specific services or resources rather than the method of VPN access itself.
