Add a Scanner to a Network

Required Vulnerability Management User Role: Scan Manager or Administrator

A scanner or scanner group is part of the default network unless you add it to a custom network. A scanner or scanner group can only be part of one network at a time.

You can only add a scanner group to a custom network if all scanners in that group belong to either the default network or the same custom network. If you try to add a scanner group that contains a scanner already assigned to a different custom network, prevents you from adding the scanner group to the network until you resolve the conflict.

You cannot add an AWS pre-authorized scanner to a network.

Before you begin:

  • Create a new network.

    Note: Tenable recommends moving scanners to a new network, rather than an existing network, to prevent unwanted asset merges. If the network where you move a scanner already contains asset records, and the identifiers for assets from the moved scanner match the identifiers already existing in the network, automatically merges those assets.

  • If you want to move a scanner from one existing network to another existing network:
    • Note the IP addresses of the assets identified by the scanner you want to move.
    • Use the IP addresses to move the assets from the first network to the second network.
    • Add the scanner from the first network to the second network. Use the steps below to add a scanner.
