High-Speed Vulnerability Discovery

The Tenable Nessus® vulnerability scanner performs high-speed vulnerability identification on the assets you choose to scan. Nessus scanners can be distributed throughout the enterprise to put the power of Nessus in the hands of the responsible parties. They can be configured to test an unlimited range of IP addresses or for DNS or MAC addresses if IP addresses are dynamic.

Audits of networks less than 100 hosts can typically be completed in a few minutes. This can be accomplished with a laptop or medium-powered server. For larger networks, Tenable SecurityCenter can be used to leverage multiple distributed Nessus scanners.

Nessus continuously scans your network devices to drastically save time identifying new vulnerabilities. Nessus can scan the systems without needing administrative credentials and can also test using common exploit techniques. If credentials are provided during the audit, Nessus can determine an exact list of missing patches and common misconfigurations. Nessus also provides integration with patch management systems — including Red Hat Network Satellite Server, Microsoft's Windows Server Update Services (WSUS) and System Center Configuration Manager (SCCM), and VMware Go (formerly Shavlik), providing an alternative source of data when traditional approaches are unavailable.
