The fast and easy way to find vulnerabilities before attackers.
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.
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.
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.
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 tailor reports by team or client which can be emailed with every scan.
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.
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.
