As configured on the Error Pages tab (Portal Account > Solutions mode > Notifications > Error Pages), the Symantec Web Security Service displays notification pages to users when a browsing action triggers an exception, such as a denied content category. The page contains default information, including the exception reason. You can also select to display information, such as contact information and a custom logo. These notification options should prove sufficient for most enterprise requirements. This information comes from a template, which you can also customize.
