Generated using AI

Last updated: Nov 04, 2026

What is Tenable Nessus, and what problem is it built to solve?

Tenable Nessus is used to scan systems and networks for vulnerabilities, misconfigurations, and missing patches. Its findings help security teams understand exposure and decide which issues to address first.

What languages does Tenable Nessus support?

Tenable Nessus supports 1 language: English.

What company sizes and industries is Tenable Nessus the best fit for?

Positive user presence spans small businesses, mid-market organizations, and enterprises, with particularly strong representation in IT and security-related fields. The segments that stand out include:
  • Company sizes: Small businesses, mid-market organizations, and enterprises.
  • Industries: Information technology and services, and computer and network security.
  • Financial sectors: Financial services and banking.
  • Public and education sectors: Government administration and higher education.

How long does it take to implement Tenable Nessus across a team?

Implementation is often completed within a month, with same-day and under-one-month go-live reports especially common. Longer rollouts also occur, particularly when setup involves more extensive scanning or configuration.

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.

"Self-Contained Nessus Scanning with Full Control in Offline Environments"
4/5
What do you like best about Tenable Nessus?

The fact that it's all self-contained and usable on a network which doesn't have useful outside connectivity makes Nessus very useful in some environments we have in our estate. Being able to be in complete control of every aspect of how it runs is great. Also being able to size the underlying host and its network architecture to be able to scan what needs to be. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

The only problem with Nessus is that it can sometimes flag up false positives because of a lack of integration with software vendors to create a joined-up approach and understanding of backports. Simply flagging on version numbers for software isn't enough in this day and age. Extending functionality to know what CVEs have been covered without changing version numbers would be a killer feature. Review collected by and hosted on G2.com.

"Powerful Vulnerability & Compliance Coverage with Clear, Actionable Reporting"
5/5
What do you like best about Tenable Nessus?

The variety of vulnerability checks available across a multitude of technologies; between vulnerability plugins and compliance checks via audit files, and various authentication methods allow for in depth automated analysis over a vast and varied IT landscape. The Nessus UI scan results view and vulnerability management capabilities afford security assessors the ability to weigh mitigation strategies quickly while reporting vulnerability status more broadly to executive decision makers. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

The Nessus licensing structure to functionality map is rather confusing. If I want to test a scan, I have to identify which type scan to run, which Nessus platform to use, ensure the license supports the type of scan, and further additional steps to perform a scan successfully Review collected by and hosted on G2.com.

4.5/5

"User-Friendly Vulnerability Scanner"
4/5
What do you like best about Tenable Nessus?

We use Tenable Nessus as our business vulnerability scanner, and appreciate its ability to scan our VLANs, report CVEs, and suggest remediation. We like that Nessus helps us stay compliant with CIS18 and ensures we aren't missing any "invisible" problems on our network. What stands out is its more user-friendly interface compared to other scanners we've used, and we find it convenient that it doesn't force us to create our own reporting. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

We would love even more customization in the UI. The ability to download additional reports, create new views, etc would be great. Review collected by and hosted on G2.com.
