According to the ServiceNow Hardware Asset Management documentation, the ServiceNow Content Service is a cloud-based service that provides content updates for hardware models, such as manufacturer, model category, and lifecycle information. The ServiceNow Content Service also collects unrecognized data from customers, such as new or custom hardware models, to improve the content quality and coverage. Customers can opt out of sending unrecognized data to the ServiceNow Content Service for specific models, but this will also prevent them from receiving content updates for those models.
