Where does PRTG store passwords used by remote probes?

We are using PRTG to monitor several windows servers in remote locations. The servers are not part of a windows domain. I'm evaluating the security implications of using remote probes for each server instead of one centralized probe on the prtg host.

What I'd like to know: - When entering Windows credentials to be used by a remote probe, are those credentials saved only on the remote probe system and not on the prtg host? - If the answer to the previous question is yes: Can the credentials be somehow retrieved in clear text by the prtg host?

Thanks for your help,

Adrian

Hi Adrian,

All passwords are stored encrypted in the PRTG configuration file. This file is transmitted to the Remote Probes, where the configuration is cached. The passwords can only retrieved in clear text by using a script/PRTG API and using the corresponding placeholders

Furthermore, regarding the plan of a "centralized probe". Please be aware that we only recommend 2500 Sensors per Probe.

Hi Moritz,

thanks for your quick reply. So, to make sure I understand this correctly: If my main PRTG server is compromised, then all passwords stored for all remote probes are also compromised?

Thanks,

Adrian

Hi Adrian,

yes that's correct. All passwords are stored on the PRTG Core Server and the Core Server distributes them along with the configuration to all Remote Probes.
