Content profiles

Use content profiles to apply different protection settings for content traffic that is controlled by firewall policies. You can use content profiles to:

•Configure antivirus protection for HTTP, FTP, POP3, SMTP, and IMAP policies

•Configure web filtering for HTTP policies

•Configure email filtering for IMAP and POP3 policies

•Configure oversized file and email blocking for HTTP, FTP, POP3, SMTP, and IMAP policies

•Pass fragmented email for POP3, SMTP, and IMAP policies

Using content profiles, you can build protection configurations that can be applied to different types of firewall policies. This allows you to customize types and levels of protection for different firewall policies.

For example, while traffic between internal and external addresses might need strict protection, traffic between trusted internal addresses might need moderate protection. You can configure policies for different traffic services to use the same or different content profiles.

Content profiles can be added to NAT/Route mode and Transparent mode policies.
