About Content Filtering and Scans
The UTM 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.
Note: Traffic that passes on the UTM's VLANs and on the secondary IP
addresses that you have configured on the LAN Multi-homing
screen (see
page 104) is also scanned for content and malware threats.
Note: For information about how to monitor blocked content and malware
threats in real time, see
