Re: "Treat all hosts monitored by the SolarWinds Orion monitoring software as compromised "
Well it depends on the permissions you gave Orion
But some of the installations I have worked on
250-2000 network devices
Anything from 100 to 1000 servers.
In fact my latest contract / job is the first in 10+ years where solarwinds isn’t the preferred monitoring platform.
I would personally never give solarwinds write permission to anything, although I know plenty of companies who do.
