Tenable Nessus Likes & Dislikes

Like

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.

Like

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. ,

Like

It's very easy to use and works really well. It will also email you with alerts for things it's found on end points.

Dislike

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.

Dislike

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.

Dislike

On rare occasions, sometimes end point credential scans will fail and it won't tell you why it failed. Usually it's pretty easy to work out what caused the failure, but sometimes it's not obvious.

    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 It will also tell you what the risk level of any outdated software it finds is, and will advise you on how to remedy the problem.
