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.

"User-Friendly IP Scanning with Audit-Friendly Compliance Reports"
4/5
What do you like best about Tenable Nessus?

It’s very user-friendly to start a basic scan of IP addresses. As a non-developer, I was able to learn the interface quickly and run the scan without much effort. The reports are audit-friendly, and we were able to submit them for compliance purposes. Review collected by and hosted on G2.com.

What do you dislike about Tenable Nessus?

The report is provided in PDF format, so we’re not able to assign specific vulnerabilities to the appropriate teams. It would be very helpful if the reports could also be exported to a format like Excel, so we can allocate vulnerabilities to the respective team members more easily.

What do you dislike about Tenable Nessus?

Costs can scale quickly – Advanced features and larger environments often require premium licensing.

UI and reporting could be better – Custom reports and dashboard features are somewhat limited.

Steep learning curve for advanced use – Complex scans (e.g., with credentials or web app auth) require deeper technical knowledge.

Authenticated and web app scanning can be finicky – May need fine-tuning to work correctly with complex login flows.

Not ideal for full lifecycle VM – Lacks built-in asset management or long-term trend analysis unless integrated with Tenable.io or Tenable.sc.

Performance overhead on large networks – Can slow down scanning or miss things if not properly resourced. Review collected by and hosted on G2.com.
