Use the Monitor > URL Categories page to view the URL Categories report. This report shows
the top 10 URL categories by completed transactions and the top 10 URL categories by
blocked transactions for a specified time range. Competed transactions include both clean
transactions and monitored transactions.

The URL Categories Matched section shows all matched categories during a specified time
range for both completed and blocked transactions. You can use column headings to sort
data, and the Items Displayed menu changes the number of URL categories displayed in the
list.

The percentage of uncategorized URLs in the URL Categories report is typically around
15-20%. If the percentage of uncategorized URLs is higher than that, consider the following
options:

• For specific localized URLs, you can create custom URL categories and apply them to

specific users or group policies. For more information, see “Custom URL Categories” on
page 301.

• You can report misclassified and uncategorized URLs to the IronPort support portal at the

following URL:

https://supportportal.ironport.com/irppcnctr/srvcd?u=http://secure-

support.soma.ironport.com/subproducts/s_series&sid=900019#

These get picked up and get evaluated for subsequent rule updates.

• Verify Reputation Filtering and Anti-Malware Filtering is enabled. Often times, the

correlation between malware and URLs with suspect content is high and it is likely that
they may get caught by subsequent filters. The system pipeline is set up to catch malicious
traffic with other downstream filters if URL filtering does not have a verdict.
