Take the guesswork out of Vulnerability Assessment with Predictive Prioritization

Powered by Tenable Research, Nessus delivers the industry’s broadest vulnerability coverage with new detections continuously added to the platform. Predictive Prioritization prioritize the most critical security issues so that you don’t have to.

More than 100 zero-day vulnerabilities discovered over the past 3 years
New plugins released within 24 hours of vulnerability disclosure (on average)

The Tenable Vulnerability Priority Rating (VPR) helps you zero in on the vulnerabilities that matter most by combining vulnerability information, threat intelligence and data science. VPR can be found in Nessus Professional Top 10 reports and within a VPR Top Threats tab for a particular scan.

Built For Practitioners, By Practitioners

Nessus was built from the ground-up with a deep understanding of how security practitioners work. Every feature in Nessus is designed to make vulnerability assessment simple, easy and intuitive. The result: less time and effort to assess, prioritize, and remediate issues. Learn more about the features here.

  • Top 10 Reporting

    Quickly understand and easily communicate the top 10 high, critical and the most prevalent vulnerabilities, all found within a scan. These top 10 reports utilize Tenable’s Vulnerability Priority Rating to understand what vulnerabilities pose the highest risk.
  • VPR Top Threats

    Create a list of top threats from your scan, based on VPR. Provide recommendations on which vulnerabilities pose the greatest risk in order to focus your remediation efforts.
  • Pre-Built Policies and Templates

    Out of the box, pre-configured templates are included for a range of IT and mobile assets - from configuration audits to patch management effectiveness - to help you quickly understand where you have vulnerabilities. Nessus includes more than 450 compliance and configuration templates to audit configuration compliance against CIS benchmarks and other best practices.
  • Customizable Reporting

    Easily create reports based on customized views, including specific vulnerability types, vulnerabilities by host or by plugin. Create reports in a variety of formats (HTML, csv and .nessus XML) and easily customize reports by team or client which can be emailed with every scan.
  • Live Results

    Live Results automatically performs an offline vulnerability assessment with every plugin update, showing you where you may have vulnerabilities based on your scan history. From here you can easily run a scan to validate the presence of the vulnerability which accelerates the accurate detection and prioritization of issues.
  • Grouped View

    Similar issues or categories of vulnerabilities are grouped together and presented in one thread, simplifying the time to research and prioritize issues for remediation. Snoozing lets you select specific issues to disappear from view for a specified period of time. So you only focus on the issues that matter at that time.

More than 30,000 organizations trust Nessus.
