Tracking Corrupt Cortex XDR Agents

L1 Bithead

I am looking for any input on how other customers are handling situations where:


1. The agent is installed on a host and says it is checking in, but it does not appear in the Cortex XDR Console

2. The agent is corrupt and has stopped reporting back (due to a failed upgrade or otherwise)


I didn't know if anyone has any unique solutions for these situations. From a corrupt agent standpoint, it would be nice to have a Tenable plugin to report back the current signature versions.




Hopefully this will save you from months of log collection. There is a known bug with agent upgrades prior to the versions below. Unfortunately all support reps are not aware. See the comment below from support that we received once the right people got involved with our ticket.


"Moving forward from 7.4.1->7.4.2 and onward you should not run into this issue"


What version are you noticing issues with?
