Tenable, in its variety of versions has a large section to train its customers, it is not a surprise that escalate positions with the passage of time and with every improvement that creates true expectations. Within the company we have deployed Nesss and it really has been helpful to fin every vulnerability that the scans throw at us, the information is very complete from the discovery stages, we feel very satisfied, that the tool has been implemented in other infrastructure and the results are very heplful.

Nessus and its graphical interface is attractive, I would say that minimalist but punctual and charming, it is very clean, it should be applauded that in each version they improve it and include some types of scans that can bring you more complete results when you carry out an analysis. It is very remarkable that the plugins in your database are up to date and that your community generates an adequate response on time.

For now all the experience I have with Nessus has been nice, with the constancy that you have in your team working every day to improve it I know it will be a good tool for vulnerability detection.

Nessus has done a spectacular job in vulnerability assessment in our company which has helped us to maintain secure environments in the cloud and on premise. Configuring nessus was a straightforward forward task and it carries out in depth scans within a short time. Nessus comes with build in vulnerabilities which you scan against your systems to find out if there are vulnerabilities present.

I like how you get an alert promptly when nessus detects an attack on any of your systems. I also like the wide variety of plug ins made available by nessus for specific vulnerabilities. I'm also impressed with how nessus allows you to create your own tests related to you company. I like how it is always releasing updates on new vulnerabilities which you can check in your systems. Nessus provides suggestions for alleviating detected vulnerabilities in your systems.

Nessus still has the issue of false positives which is common in most vulnerability scanners whereby nessus detects vulnerabilities that are not present. It is not user friendly in terms of costs since it is expensive if you want to access more features through the paid versions. Aside from that, I am certain that we have been able to get the best from this tool.

The client side agent is lightweight and easy to deploy once you get it successfully installed and reporting in. The adminstrative console is somewhat confusing, but provides very detailed reports that you can customize to your liking.

Does what it is supposed to. Provides a good overview of vulnerabilities across systems for internal security assessments and audits. Easy to deploy MSI package

Support is something to be desired. During initial setup in our environment, there were several complications when attempting to connect machines to the tenable.io cloud and provide the client machines with updates. The support group couldn't provide necessary assistance and we ultimately left to troubleshoot on our own.

Nessus is easy to use and easy to deploy vulnerability assessment solution available. One of the best features is nessus can be easily deployed to air gapped environments without much changes to the environment.

Nessus has limited reporting and vulnerability management features as compared to other tools.

Great tool for vulnerability scanning, easy to use, full of very useful features.

Nessus allows you to run vulnerability scans to multiple networks simultaneously. It has various features that can be used for specific scans (web, PCI DSS, etc), as well as generic scans. Very easy to use. The reporting feature is also great, as it is very well formatted and it's possible to export the results into various formats.

Everything is great as is in Nessus, especially if compared to other competitors. Nothing negative to say about it.
