The SmartFilter URL Blacklist list provides a comprehensive and proven database of millions of global URLs that are organised into 70+ categories. These categories include sites that organisations may want to control access to such as liability, security, productivity, and bandwidth-intensive sites.

The SmartFilter list also provides numerous categories that organizations typically don’t block but rather use to better understand their Web traffic and include sites such as business and reference.  

*This list may not be exhaustive - new categories are added all the time.
