The thing I like most about Tenable Nessus is its ease of use. I also like that it has highly customizable scans. Compared to other tools I have used in the past, Nessus has more plugins/add-ons, tests, and templates. In addition to being easy to set up, it provides you with the ability to safely migrate applications to the cloud. Tenable Nessus scales well with good VPR scores too, and so far I haven’t experienced any challenges. Another feature I really like about it is the plug-in text information, which I find to be quite useful. Overall, from what I can tell, the solution is also very stable and fast. One downside is that I feel the technical support has been quite disappointing.
Qualys VM is excellent. It successfully provides continuous monitoring, it is simple to install, easy to maintain, good for scaling, and has very helpful technical support. Qualys VM also includes asset tagging and asset grouping, which I really like. Their dashboard is also flexible, allowing you to customize it any way you need to. While Qualys VM is a great solution and is reasonably steady, it also has a lot of room for improvement. 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. It does not have any features for scanning SCADA, Industrial Control Systems, and IoT. And the solution itself is pretty generic and could benefit from the addition of more assets.
Conclusion: Tenable Nessus was the right choice for me because it fulfilled my business requirements, but also because I felt Qualys VM still has a long way to go.
Tenable Nessus is a vulnerability assessment solution that is both easy to deploy and easy to manage. The design of the program is such that if a company should desire to handle the installation themselves, they would be able to do so. The updates that the program requires to keep up-to-date take up a large portion of the setup time. Tenable Nessus can be deployed in under an hour. The speed of an organization’s internet can impact how quickly the deployment will go. Furthermore, once it has been set up, only a small management team is necessary for maintenance. Tenable Nessus is an incredibly important program that provides businesses and organizations with robust protection. This ease of deployment and management gives it an edge over the competition.
Tenable.io Vulnerability Management is basically comparable to Tenable Nessus in regards to setup and management. It is relatively straightforward to set up. A single person could deploy it in a non-business setting in a matter of hours. The setup can be handled without requiring a business to rely on the help of outside consultants. As with Tenable Nessus, a small team of two or three people is all that is necessary to manage the solution. Organizations can save a great deal of time and resources by choosing to utilize this solution.
Tenable Nessus is a solution with good scalability. This can be accomplished with relative ease. However, the load that it can handle makes it a poor fit for larger organizations. At a certain point, the farther up you scale it, the more the solution quality diminishes.
Tenable.io Vulnerability Management is able to offer a much higher level of scalability. It is typically used without trouble by organizations with many thousands of users. As with Tenable Nessus, the process is relatively simple.
The actual difference in time and ease as far as deploying Tenable Nessus versus Tenable.io Vulnerability Management is negligible and cannot truly set one apart from the other. Ease of management is another area where these two solutions are very similar. A major difference between them is their scalability. While both can be scaled relatively easily, Tenable.io Vulnerability Management is able to handle a higher level of scalability, with the diminishment of quality being a far lesser concern than is the case with Tenable Nessus.

Both, but I prefer Nessus Pro (costs and you can define out-of-band your better presentation/xLAP platform).
Tenable.io has its facilities and extra plugins/views/analytics, but nothing that can't be externally performed by another ETL/presentation tool (for a fraction of cost, sometimes using free toolings like Pentaho, OpenRefine, OBIEE and others).
