SmartFilter Database
Internet access is managed and monitored through the the powerful
combination of reputation-based filtered powered by TrustedSource™
and SmartFilter® database. The filtering database provides a comprehensive
and proven source of millions of global URLs that are organized
into over 91 categories. These categories include sites that organizations
may want to control access to such as liability, security, productivity,
and bandwidth-intensive sites. The SmartFilter database 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.
Consistently ranked most accurate filtering
Independent studies have consistently named Secure Computing as
having the most accurate database with top rankings in various reports.
Why is database quality so important?
A filtering database of lesser quality may still block plenty of
sites, but it will also either let more inappropriate content through,
block appropriate content, or both. The result of using a less-effective
filtering product is more requests for help from users, and worse,
more access allowed to offensive and possibly dangerous content.
How the best database in the industry is built and maintained
Secure Computing relies on a combination of advanced technology
and highly skilled Web analysts – the ideal combination for high
accuracy and coverage. Secure Computing utilizes a number of technologies
and artificial intelligence techniques to gather and rate potential
Web sites including: link crawlers, security forensics, honeypot
networks, sophisticated auto-rating tools and customer logs. Candidate
sites are added to the SmartFilter database after being reviewed
by our multi-lingual Web Analysts who focus their full attention
on ensuring the continued quality of the database.
Web Analysts bring a wealth of experience
Our Web analyst team brings a wealth of technical expertise and
cultural diversity that's unmatched in the industry. Our SmartFilter
database contains URLs from 66 different countries where unique
languages are spoken. Large numbers of URLs are in Arabic, Chinese,
Czech, Danish, Dutch, Finnish, French, German, Hebrew, Icelandic,
Italian, Japanese, Korean, Norwegian, Polish, Portuguese, Russian,
Spanish, Swedish, and Turkish.
Outstanding customer service
Have a question on how a site is categorized? Customers can either
use the online URL checker found on TrustedSource to determine how
a site is categorized or communicate directly with the Web Analyst
team. Customers can file tickets to track their URL request and
receive detailed reports on how URLs in question are categorized.
Real-time updates and feedback
Updates to the SmartFilter database are now available in real-time,
helping you keep up with the changing nature of Internet content
and stay ahead of emerging Web threats. SmartFilter also offers
real-time automated feedback that sends uncategorized URLs to the
TrustedSource network for review.

with SmartFilter 4.2 and later):

use of alcoholic beverages, including beer, wine, and hard liquors.
This also includes cocktail recipes and home brewing instructions.
Anonymizers (an) This category includes URLs that enable anonymous

that provide free proxy IP addresses or detail how to bypass filtering
are also included in this category.

sites (including sculpture and photography), and other cultural
topics, such as museums, ethnic customs and country customs.

This category includes URLs that offer access to online auctions
and classified ads. Online auctions are rarely monitored; therefore
these sites may expose users to material that would otherwise be

frequently to monitor the progress of their bids or items for sale.
Blogs/Wiki (bl)

quickly and spontaneously such as Web logs (blogs) or wikis. This
category is intended to cover the risks associated with content
