INTERNET THREAT DATABASE FILTER
The Internet Threat Database Filter enables you to maximise message filtering by using SurfControl’s
database of 9 Million URLs. Each category contains a list of URLs that have been added and are
constantly updated by a team of SurfControl researchers. These categories enable you to apply a rule to a
group of URLs rather than having to enter each one individually.
You also have the option to add specific URLs that are not covered in the categories already provided.
Configuration of the Internet Threat Database Filter is carried out in the Internet Threat Database Filter
screen.
