What customer support options does Tenable Nessus provide, and how do users find the overall support experience?

Tenable Nessus support is available through self-service resources and direct channels, including chat, email/help desk, and phone support. The experience is mixed: users describe helpful, knowledgeable assistance and quick ticket responses, while others encounter slow replies, delays scheduling calls, or difficulty resolving technical issues.

What is the experience like for teams switching to Tenable Nessus from another tool?

Teams switch to Tenable Nessus from tools such as OpenVAS, Qualys, and Rapid7 products when they want a simpler workflow, broader or more current vulnerability coverage, or findings they consider more accurate. Some also move for better value or to replace tools that were harder to administer, slower to scan, or less consistent in their results.

What features or capabilities could make Tenable Nessus even more useful?

More flexible reporting and management views would make Tenable Nessus easier to use across different audiences and workflows. Users also want improvements that reduce manual follow-up and make scan operations and results easier to manage, including:

Reporting: More customizable reports, clearer summaries and visualizations, and exports that are easier to share with management or assign to teams.
Finding accuracy: Fewer false positives and better handling of cases such as backported patches, so teams spend less time validating results manually.
Workflow and administration: Stronger remediation tracking, scan-history retention controls, and more flexible user roles, tagging, and automation.

Is Tenable Nessus considered safe and secure for handling data?

Tenable Nessus helps security teams identify vulnerabilities, misconfigurations, and patch gaps so they can assess exposure and prioritize remediation. Scan results can still require manual validation, since noisy findings and false positives sometimes add review work.

"One of the best vulnerability scanners on the market"

4/5

What do you like best about Tenable Nessus?

Nessus was very easy to install, and we were up and running in very little time. There are lots of various scan type options to choose from. Our third party auditors also use Nessus for internal vulnerability scans, and we were able to import their scanning template in order to do accurate post remediation scans. We were able to easily setup a weekly scan schedule. Product updates are simple and straight forward, and we receive notification when new versions are available. The price was also within our budget. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

I wish Nessus had a vulnerability remediation option. Finding all the detailed vulnerabilities is only half the battle, researching the vulnerability and the fix is also time consuming. Nessus does have links to the CVE or KB docs, and many times remediation recommendations, but the patching process is still manual. I realize that automatic remediation may not always be the best practice depending on the vulnerability, the system/device, and various other factors, but possibly some options for simple patches would be very useful.

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

It finds and categorizes all vulnerabilities on all device types. Our previous product would only work with Windows devices for instance, so you are not getting a complete picture of your entire network. Vulnerabilities are categorized based on criticality, so you can prioritize your remediation process. Review collected by and hosted on G2.com.

That the technology is still On-Premises and this leads to infrastructure expenses, which generates additional costs for the organization and depreciation of this used hardware. Review collected by and hosted on G2.com.

"Nessus Professional has the best price/coverage ratio of the industry"

5/5

What do you like best about Tenable Nessus?

Tenable Nessus Professional is widely praised for several key features that make it a preferred choice for vulnerability management BUT I want to focus my review on why it make sense for you if you have a lot of IP to scan. Most of the scanners have licenses per IP, so if you have wide IP ranges, licenses fee would be astronomious. You will need to accommodate the limited reporting and vulnerability management feature of the professional version. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

Nessus Professional need some good process OR automation to get the most of it as you dont have any 'quality of life' feature like dashboard, tracking and limited automation. Review collected by and hosted on G2.com.
