We welcome submissions of previously unknown or uncategorized sites, which will be taken into consideration by our URL categorization providers. Because of the requirement to optimize database size and performance we cannot make any guarantee that sites submitted will be added to our database. We are also unable at this time to provide feedback on the categorization process or the status of submitted sites. We are working to develop processes that will provide more transparency for customer feedback in the future.
The Sophos Web Appliance has a "Local Site List" that can be used by an administrator to classify these sites immediately. The Help menu for the appliance can be used to further explain how to do this, or follow the link here.
