Link to Tenable Security Center

During initial installation, you can install Tenable Nessus as a remote scanner linked to Tenable Security Center. If you choose not to link the scanner during initial installation, you can link your Tenable Nessus scanner later.

Note: Once you link Tenable Nessus to Tenable Security Center, it remains linked until you unlink it.

Note: Tenable Security Center does not send plugins to linked Nessus Managers. Nessus Manager pulls plugins directly from Tenable's plugin sites. Therefore, to update plugin sets, Nessus Manager needs access to the internet and Tenable's plugin sites (for more information, see the Which Tenable sites should I allow? community article). If your Nessus Manager does not have internet access, you can manually update its version and plugins offline (for more information, see Manage Nessus Offline).

Before you begin:

  • Configure Tenable Nessus as described in Configure Tenable Nessus.
  • If the Tenable Nessus scanner is or was previously linked to Tenable Vulnerability Management, Tenable Security Center, or Tenable Nessus Manager, you need to unlink the scanner or run the nessuscli fix --reset-all command (for more information, see Fix Commands).

To link Nessus to Tenable Security Center:

  1. On the Welcome to Nessus, select Link Nessus to another Tenable product.

  2. Click Continue.

    The Managed Scanner screen appears.

  3. From the Managed by drop-down box, select

  4. Click Continue.

    The Create a user account screen appears.

  5. Create a Tenable Nessus administrator user account, which you use to log in to Tenable Nessus:

    2. In the Password box, enter a password for the user account.

      Note: Passwords cannot contain Unicode characters.

  6. Click Submit.

    Tenable Nessus finishes the configuration process, which may take several minutes.

  7. Using the administrator user account you created, Sign In to Tenable Nessus.
