What does the HTML5 Gateway eliminate the requirement for?

The HTML5 Gateway enhances security and accessibility by eliminating the need for a direct RDP connection. With traditional remote desktop protocols, users would typically connect directly to target systems over the network, which could expose those systems to unnecessary risks. By using an HTML5 Gateway, users connect through a secure web interface, which abstracts the underlying details of the direct connection and reduces the attack vector associated with direct RDP access.

This approach ensures that sensitive credentials and details about the remote system are kept more secure and that the connections are made over encrypted channels. Additionally, using HTML5 means that users can access their systems from various devices and platforms without requiring specific client software to be installed, which is a significant improvement in terms of usability and security.

While the other options referenced in the question may also have relevance in a context of network security, they are not the primary requirement that the HTML5 Gateway specifically addresses.
