Hi Larry
We have been using QVM for 2.5 years now. Therefore, I can say that we already have a lot of experience with this module.
First, the look and feel has not changed in these 2.5 years. If you expect a modern VM tool, then you should look around the competition. It is positive that you only have to serve one platform from one vendor. The asset database in QRadar is also supplied with the vulnerability results, so there are more possibilities in the SIEM area. However, this strength is also a weakness.
We have about 28 scanners in use (managed hosts) and a dedicated scan processor. Thus, 29 managed hosts are connected to QRadar. With each deploy of the qradar console long waiting times are possible, or a deployment cannot be carried out, if a managed host does not react.
The scans take relatively long. At least if you scan with authentication. Since update 7.3.2 Patch 2 the scan performance has improved by 50%. The long scan duration is not necessarily due to the scanners, but much more to the processing of the scan results on the QVM Processor.
Something else you should know. The scanners authenticate via NTLMv2 at the Windows endpoints. If you only allow Kerberos in your company via policy, the scanners can no longer authenticate at those endpoints. For us, this means that as time goes by we get less and less insight into Windows servers. With Linux systems, we authenticate ourselves via certificate. A request for enhancement regarding this topic has been rejected.
We also had to outsource the analysis of the scan results. This means that I export the results via API and present them on an external dashboard (Power BI).
If you need further information regarding QVM, just ask.
Hope I could give you some practical insight.
