All web browsing activity is recorded to an SQL database that can be either be viewed on screen or exported for external analysis. An extensive range of detailed reports can be generated to show anything from 'most visited domains' and 'top blocked categories' to time spent browsing and bandwidth utilization. Where authentication is enabled, reports can also be generated by user or group so that the worst offending users (in terms of requesting pages that were blocked by Guardian) can be quickly identified.
Reports can also be easily customized, with a drill-down facility that allows the data to be explored to a much greater depth. For example, from a list of blocked sites that students have attempted to access, it is possible to drill-down to find out exactly which individuals have been trying to access any particular site.
Reports can also be produced in a graphical format appropriate to the report contents such as pie charts and bar graphs, saved in familiar file formats such as PDF and Excel, or emailed to a distribution list. User Agent Reporting can be used to identify non-standard browsers or other software using the web (such as spyware) and AJAX based real-time logs and traffic graphs show instantaneous web activity.
Automatic data aggregation from multiple remote systems provides network-wide reporting. The new report template facility allows administrators to create, store and schedule their own reports, as an alternative to the existing integration with Crystal Reports®.
Under normal circumstances Network Guardian will run for weeks or months without the need for human attention. However, should the system detect unusual web activity or a hacker decide to attack either the firewall or one of the systems it is protecting, then Network Guardian can make network administration staff aware of the incident by sending alert messages to cell (mobile) phones.
