Hi @RajeshPremSingh, thank you for writing to Live Community.


The 'failed connections' alert is an XDR Analytics alert that indicates that the endpoint has failed connections to other endpoints that have been inactive for more than 24 hours, or that Cortex XDR Analytics has never seen on the network. You can read more about the alert and which investigative options you can potentially take here.

That said, I'm not entirely sure what you are asking. Could you please elaborate?







Could you elaborate on what is the ask here?
