"Poorna's Nessus Review"

5/5

What do you like best about Tenable Nessus?

Nessus is one of the best tools in vulnerability assessment technology. It is effortless and very effective in identifying any CVEs present in the servers. Practically effective in identifying the lack of security patches. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

There are some issues with Nessus in the report-making process, and mostly FP cases pop up, which must be lowered. Sometimes asset grouping is formidable. And the pricing may not suit everyone. Apart from these, it has no significant flaws. Review collected by and hosted on G2.com.

"Nessus Professional makes my job easier"

5/5

What do you like best about Tenable Nessus?

Nessus takes the guesswork out of finding out what needs to be addressed and helps you determine what's most critical in your environment. The process of finding vulnerabilities is simple and intuitive and it constantly keeps up with newly discovered vulnerabilities that arise and helps you detect them in your environment. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

There isn't anything about Nessus Professional that I don't like. In three years of using Nessus Professional, we've not had any issues with the scan results in our environment. Review collected by and hosted on G2.com.

What problems is Tenable Nessus solving and how is that benefiting you?

Before we used Nessus Professional, we used several tools to determine potential vulnerabilities in our environment. However, they had inconsistent reporting and didn't keep up with newly released vulnerabilities. Now we have one tool that can scan for vulnerabilities and even check that we're compliant with best practices. Review collected by and hosted on G2.com.
