Im a consultant, can I use Nessus 4.4 to conduct my clients audits?
A. Tenable permits you to use Nessus to audit the security of 3rd party networks but requires that you purchase a ProfessionalFeed Subscription. You must subscribe to the ProfessionalFeed to use it commercially with the latest updates and have access to technical support and knowledgebase articles. A HomeFeed cannot be used for consulting commercially. A very common scenario for Tenable is to license several ProfessionalFeeds to a service provider who operates an equivalent number of Nessus scanners to check for vulnerabilities on their customers’ systems and networks. The ProfessionalFeed license is tied to the Nessus scanner. If the Nessus scanner is mobile (such as on a laptop), then the license is mobile. We do not tie it to an IP address. There is no limitation to the amount of scans completed or IPs scanned. However, the Tenable Plugins are licensed only for use with Registered Nessus scanners obtained directly from www.nessus.org or www.tenable.com.
