If you are using the Tenable SecurityCenter, the Activation Code and plugin updates are managed from
SecurityCenter. Nessus needs to be started to be able to communicate with SecurityCenter, which it will
normally not do without a valid Activation Code and plugins. To have Nessus ignore this requirement and start
(so that it can get the information from SecurityCenter), input “SecurityCenter” (case insensitive) without
quotes into the Activation Code box. After starting Nessus, SecurityCenter users have completed the initial
installation and configuration of their Nessus scanner and can continue to the section “Working with
SecurityCenter”.
If you do not register your copy of Nessus, you will not receive any new plugins and will be unable to start the
Nessus server. Note: The Activation Code is not case sensitive.
If you select offline for your activation, please note that “offline” is case sensitive.
