Detect known or suspicious malicious processes and botnets. Nessus enhances an organization's anti-virus strategy by red-flagging threats that often slip through the cracks, helping fight malware and advanced persistent threat (APT).
Patch Management Integration

Multi-scanner Support, Post-scan Analysis, & Customized Monitoring
Nessus provides users with multi-scanner control, email notifications of scan results, a remediation report, enhanced post-scan analysis tools, vulnerability modifications, and suggestions for more complete audits.
Organizations with multiple Nessus scanners for different network segments and geographical locations can control all their scanners from one place. Configure a primary Nessus scanner on premise or in the cloud (Nessus Perimeter Service) to control multiple secondary scanners, schedule internal scans, and view scan findings.
Providing an actionable list to help with remediation efforts, Nessus summarizes the actions to take to address the largest quantity of vulnerabilities on the network. The report is included in scan summary email notifications, as a report chapter, and on the Remediations tab in the user interface.
Targeted Email Notifications
Nessus can send an email summary of completed scan results and remediation recommendations to selected recipients. For individual scans or in conjunction with scan scheduling, Nessus can monitor for specific conditions and deliver findings to the right people.
Attachments Stored in Scan Reports
Scan results contain remote screenshots via RDP and VNC, as well as “pictures” of scanned websites, providing easy access to supporting information for post-scan vulnerability analysis and documentation.
Change the severity of findings or suppress them for a single host, a single scan, all future scans, or a specific time period. When combined with other Nessus features, users enhance the power of Nessus for daily vulnerability management.
Built-in Scanning Recommendations
Every network is different, and tuning your Nessus scan policy can yield great results. Nessus analyzes the scan results for your environment and the scan settings that were used, and then suggests improvements for a more complete audit.
