This method has agent less access benefits. This feature works without any agent installed in the target machine. Using this method, you can provide access to the target RDP machine through a standard RDP client. This feature provides the ability to access Privileged Account Manager functionality without an agent for Privileged Account Manager on the target host. RDP Relay allows users to connect to a remote host without knowing the privileged account credentials such as password or identity certificate of the user. RDP Relay session videos can be captured only if the Privileged Account Manager is in Linux environment.
The functionality also provides clientless benefits. It is called "clientless" because no plugins or client software is required. Remote desktop gateway supports standard protocols like RDP and SSH. Once the agentless module is installed all you need to access your desktops is a web browser.
NOTE:You cannot add scripts when you are using RDP Web Relay.
