Web Filtering Events and Log Overview
Use this page to view information about security events based on Web filtering policies. Web filtering allows you to permit or block access to specific websites by URL or by URL category using cloud-based lookups, a local database, or an external Websense server. Analyzing Web filtering logs yields useful security management information such as users detected accessing restricted URLs and actions taken by the system. Using the time-frame slider, you can quickly focus on the area of activity that you are most interested in. Once the time range is selected, all of the data presented in your view is refreshed automatically. You can also use the Custom button to set a custom time range.
Web Filtering Events—Summary View
Click Summary View for a brief summary of all the Web filtering events in your network. The top of the page has a swim lane graph of all the Web filtering events against the blocked events.
You can use the widgets at the bottom of the page to view critical information such as top URLs blocked, top matched profiles, top sources, and top destinations. See Table 1 for descriptions of the widgets in this view.

Web Filtering Events—Detail View
Click Detail View for comprehensive details of events in a tabular format that includes sortable columns. You can aggregate the events using the Group by option. For example, you can group the events based on source country. The table includes information such as the event name, UTM category, source IP address, source country and so on.
The Legacy Node option is displayed in the event viewer after the legacy log collector node is added on the Logging Nodes page. We’ve added the legacy log collector support only for read only purpose to view existing log collector data. New logs should point to Security Director Insights VM as the log collector. Select the Legacy Node checkbox to view the existing log collector data. When you clear the Legacy Node checkbox, Security Director Insights log collector data is displayed.
