What technology solution does a user utilize when connecting to a remote desktop using WebSockets?

When connecting to a remote desktop using WebSockets, utilizing a clientless VPN is advantageous for several reasons. First, clientless VPNs allow users to access network resources through a standard web browser without needing to install specialized client software. This is particularly relevant in situations where users need quick and easy access to remote desktop services from various devices or locations.

WebSockets provide a full-duplex communication channel, which is essential for enabling real-time interactions within web-based applications, including remote desktop interfaces. By integrating WebSockets into a clientless VPN infrastructure, organizations can facilitate seamless communication between the user's browser and the hosted remote desktop environment.

This setup ensures that users can authenticate and maintain a stable connection to the remote desktop without requiring a heavy client application, making it more convenient and flexible, especially in environments where device compatibility and ease of access are priorities.

In contrast, the other options like SSL VPN, site-to-site VPN, and IPSec VPN involve more complex setups that typically require a dedicated client application or are focused on different use cases like secure site connections or encrypted communication between networks rather than providing direct browser access to remote desktop environments.
