There are more Uncategorized requests than expected
A new web protection installation includes a small, partial URL database that allows policy enforcement to begin as soon as the installation is complete. This limited database includes primarily URL information related to security sites. As a result, non-security URLs are unlikely to be found in the database and are therefore assigned to the “Miscellaneous - Uncategorized” category.
As soon as you enter a valid subscription key in the management console, Filtering Service begins to download the full Forcepoint URL Database. Once the download is complete, the partial database is no longer used and URLs are categorized properly. (Note that log records that are already in the database are not updated to assign correct categories.)
While Forcepoint researchers pride themselves on their ability to categorize websites, new or rarely accessed URLs may be assigned to the Miscellaneous - Uncategorized category for a time. To help limit the number of uncategorized sites, enable WebCatcher and allow it to forward uncategorized URLs to Forcepoint researchers for review. See What is WebCatcher? for more information.
