You have ruled out technical issues on your appliance:
A valid BCWF license is correctly installed on the ProxySG
You've verified the overall content filtering configuration, ruling out configuration errors
Your ProxySG is configured to only use the main BCWF database. WebPulse/DRTR are not enabled.
Reports suggest that when this occurs, it is more often for lesser-known sites rather than URLs of big name corporations or other large organizations.
The core reason for the discrepancy in the results is likely to be that when you looked it up, the tested URL only has a WebPulse categorization, and hasn't yet been added to the BCWF categorization database.
URLs which fit this criteria will have a note on the Site Review webpage stating, "Rated by WebPulse service". URLs which have already been added to the BCWF database will instead have a note stating the date when they were last reviewed.
This is expected behaviour, and is a result of the process by which WebPulse category ratings are added to the BCWF database.
BlueCoat's WebFilter team use a variety of processes to categorize web sites based on data submitted to WebPulse. A URL's popularity and frequency of lookup have an impact on how quickly it will be added to the BCWF database to download to your ProxySG appliance. Often, (though not always) human eyes must confirm the verification before it is added to the database.
To ensure that your ProxySG appliance makes use of the most up-to-date categorization data, enable the WebPulse service and the real-time categorization options as follows:
SGOS 6.6.x: in Configuration > Threat Pulse > WebPulse.
Earlier: Configuration > Content Filtering > Blue Coat > WebPulse
