    Filtering and Viewing Assets

    A Filter panel allows customers to refine which assets are displayed, offering preset filters such as Sites and Default tabs. The panel can be opened or closed using the filter icon. Assets can be viewed in three formats: List view, Gallery view, and Map view, accessible via icons in the top right of the assets list.

    Actions Available

    The Actions button provides a dropdown menu for managing assets, including importing, exporting (in CSV or JSON), updating manufacturer data, vulnerability data, product mappings, Purdue levels, ignoring assets, and deleting assets. Inactive actions appear grayed out, ensuring clarity on available options.

    Asset Records Management

    Selecting an asset’s IP address opens the asset record, where details can be viewed and edited. Adding a new asset opens the same interface with three tabs—Details, Images, and Modules—available when viewing existing records.
