About Content Filtering and Scans
The UTM provides very extensive Web content and e-mail content filtering options, Web
browsing activity reporting, e-mail anti-virus and anti-spam options, and instant alerts via e-mail.
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 “Configuring Multi-
Home LAN IPs on the Default VLAN” on page 4-11) is also scanned for content
and malware threats.
Note: For information about how to monitor blocked content and malware threats in real-
time, see “Monitoring Real-Time Traffic, Security, and Statistics” on page 11-14.
For information about how to view blocked content and malware threats in the
logs, see “Querying Logs and Generating Reports” on page 11-32.
