Deletes tag values in bulk. If you delete an asset tag, Tenable Vulnerability Management also removes that tag from any assets where the tag was assigned. If you delete all asset tags associated with a category, Tenable Vulnerability Management retains the category. You must delete the category separately.
Requires the Scan Operator [24] user role. See Roles.
