Antivirus protection
FortiGate ICSA-certified antivirus protection scans web (HTTP), file transfer (FTP),
and email (SMTP, POP3, and IMAP) content as it passes through the FortiGate unit.
FortiGate antivirus protection uses pattern matching and heuristics to find viruses. If a
virus is found, antivirus protection removes the file containing the virus from the
content stream and forwards a replacement message to the intended recipient.

FortiGate antivirus protection can also identify and remove known grayware
programs. Grayware programs are usually unsolicited commercial software programs
that get installed on PCs, often without the user’s consent or knowledge. Grayware
programs are generally considered an annoyance, but these programs can cause
system performance problems or be used for malicious means.

If the FortiGate unit contains a hard disk, infected or blocked files and grayware files
can be quarantined. The FortiGate administrator can download quarantined files so
that they can be virus scanned, cleaned, and forwarded to the intended recipient. You
can also configure the FortiGate unit to automatically delete quarantined files after a
specified time.

The FortiGate unit can send email alerts to system administrators when it detects and
removes a virus from a content stream. The web and email content can be in normal
network traffic or encrypted IPSec VPN traffic.

Web content filtering
FortiGate web content filtering can scan all HTTP content protocol streams for URLs,
URL patterns, and web page content. If there is a match between a URL on the URL
block list, or a web page contains a word or phrase that is in the content block list, the
FortiGate unit blocks the web page. The blocked web page is replaced with a
message that you can edit using the FortiGate web-based manager.
