Performance of Tenable Nessus Across Market Features

Tenable Nessus Likes & Dislikes

The simplicity for setup and ease of use is what I like the most. Also, being one of the leading names in the vulnerability scanner and management platforms ensures that we are utilizing a platform that is constantly being updated with the latest threat knowledge.

It offers extensive coverage, detection, and analysis of a broad range of vulnerabilities across different types of processes, including normal and authentication scans, and also combines local and network-based testing effectively. ,

I quite like some of the features we're currently using within the Exposure Management and Vulnerability Management blades, but mostly the remediation projects and goals, it's quite a useful feature for remediation tracking and ownership.

The support from Tenable for the service is pretty lack luster and usually requires some follow-up to get the answers I need. Luckly, the product seems to work pretty well so it's not often that I need to contact support.

In some cases, reports from Tenable Nessus can be bulky and not in the proper format, with a need for better integration of reporting between instances.

It's an excellent product, however, it takes a bit getting used to, the dashboards creation and customisation as well as the overall feel of the tool requires getting used to.

I have found some of the features to be awesome, the exposure management and vulnerability management blades but most importantly, the remediation blades, where projects can be created and assigned to owners to help track vulnerabilities as they appear.

Nessus Effectively Identifies Vulnerabilities And Helps Resolve Them

Jan 23, 2026

We use Nessus to scan end points and servers for any potential vulnerabilities, which is extremely helpful when it comes to system audits. Nessus will scan and provide you with a list of all issues found, and even put them in order of most at risk. It will also tell you what the risk level of any outdated software it finds is, and will advise you on how to remedy the problem.
