" Symantec's patent-pending URL Filters technology leverages key infrastructure elements unique to Symantec. Using its real-time spam data, the BLOC builds a list of spammer's Web sites. At the customer site, URL Filters compare embedded links in messages to the list of spam URLs maintained by the BLOC.
The list itself is created by using a combination of offline and real-time processes, incorporating URLs fromthe following sources:
Probe Network data. The majority of the spam URLs are extracted from incoming spam and historical data from the Probe Network. Thus, if there are URLs present in the message, and the BLOC has ruled against the message, the URL is added to the list.
Trusted third party lists. URL lists maintained by third party vendors and partners are verified, cross-checked, and incorporated into Symantec's spam URL list. "
Patent Pending? Third Party? Hmmm........
I have a problem with people making money off open source. I have a REAL problem when people don't even mention the source. I'm not saying they do use surbl.org, but if they did, they should say it.
They also say that URL filtering is exclusive to brightmail. Nice!
