It does not have any features for scanning SCADA, Industrial Control Systems, and IoT. Although their dashboard is customizable, it would be better if it had different tabs that allowed you to see trending vulnerabilities so that the trend analysis is easier. While Qualys VM is a great solution and is reasonably steady, it also has a lot of room for improvement. Their dashboard is also flexible, allowing you to customize it any way you need to. Qualys VM also includes asset tagging and asset grouping, which I really like. It successfully provides continuous monitoring, it is simple to install, easy to maintain, good for scaling, and has very helpful technical support. One downside is that I feel the technical support has been quite disappointing. Overall, from what I can tell, the solution is also very stable and fast. Another feature I really like about it is the plug-in text information, which I find to be quite useful. Tenable Nessus scales well with good VPR scores too, and so far I haven’t experienced any challenges. In addition to being easy to set up, it provides you with the ability to safely migrate applications to the cloud. Compared to other tools I have used in the past, Nessus has more plugins/add-ons, tests, and templates.

I also like that it has highly customizable scans. The thing I like most about Tenable Nessus is its ease of use.
