Tenable Security Center Licensing Requirements

Tenable Security Center requires a license key and a maintenance code, which may be purchased directly from Tenable Network Security or via a purchase order through Authorized Enterprise Partners. The license key and maintenance code will be used when installing and configuring your copy of Tenable Security Center.

Tenable Security Center is licensed by the total number of active IP addresses it manages and the hostname of the system on which it is installed. For example, a customer can purchase a 500 IP Tenable Security Center license for the hostname of “security”. This key allows that particular server to scan several networks, but as soon as 500 IP addresses are discovered, the license limit becomes active. There is no licensing limit to the number of Tenable Nessus installations that can be deployed with Tenable Security Center.

You will need to provide the hostname of the machine on which Tenable Security Center will be installed to or on the Tenable Community site, as described in the Tenable Community Guide. This can be obtained by entering the “hostname” command at a system shell prompt.

For more information about license counts and adding licenses to Tenable Security Center, see Licenses in the Tenable Security Center User Guide.
