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.
