Nessus includes more than 450 compliance and configuration templates to audit configuration compliance against CIS benchmarks and other best practices.

Pre-Built Policies and Templates

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.

Live Results
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.
