URL scanning analyzes email content for embedded URLs and classifies them according to a Websense database of known spam URLs. When you select the URL scanning filter type in the Main > Policy Management > Filters > Add (or Edit) Filter page, mark the URL scanning check box to display a list of URL categories in the Filter Properties area. Select the URL categories that you want Email Security to detect. When the filter detects a URL in a message from a selected category, it applies any configured filter response.

This filter is available only when your system includes Websense Web Security and a download server is configured. See URL scanning with Web Security for more information about integrating with Web Security to use this filter.

Select the URL categories for which you want the filter to scan in the URL Categories list by marking the appropriate check boxes. Mark the All check box to select all URL categories in the list.

Dashboard charts summarize the instances of embedded URLs that Email Security detects. See Available dashboard charts for the names of these charts.
