About Content Filtering and Scans
The STM provides very extensive Web content and email content filtering options, Web
browsing activity reporting, email antivirus and antispam options, and instant alerts via email.
You can establish restricted Web access policies that are based on the time of day, Web
addresses, and Web address keywords. You can also block Internet access by applications
and services, such as instant messaging and peer-to-peer file sharing clients.
