FortiGate web content filtering also supports FortiGuard web category blocking. Using
web category blocking you can restrict or allow access to web pages based on
content ratings of web pages.

You can configure URL blocking to block all or some of the pages on a web site. Using
this feature, you can deny access to parts of a web site without denying access to it
completely.

To prevent unintentionally blocking legitimate web pages, you can add URLs to an
exempt list that overrides the URL blocking and content blocking lists. The exempt list
also exempts web traffic this address from virus scanning.

Web content filtering also includes a script filter feature that can block unsecure web
content such as Java applets, cookies, and ActiveX.

Spam filtering

FortiGate spam filtering can scan all POP3, SMTP, and IMAP email content for spam.
You can configure spam filtering to filter mail according to IP address, email address,
mime headers, and content. Mail messages can be identified as spam or clear.

You can also add the names of known Real-time Blackhole List (RBL) and Open
Relay Database List (ORDBL) servers. These services contain lists of known spam
sources.

If an email message is found to be spam, the FortiGate adds an email tag to the
subject line of the email. The recipient can use the mail client software to filter
messages based on the email tag. Spam filtering can also be configured to delete
SMTP email messages identified as spam.

Firewall

The FortiGate ICSA-certified firewall protects your computer networks from Internet
threats. ICSA has granted FortiGate firewalls version 4.0 firewall certification,
providing assurance that FortiGate firewalls successfully screen and secure corporate
networks against a range of threats from public or other untrusted networks.

After basic installation of the FortiGate unit, the firewall allows users on the protected
network to access the Internet while blocking Internet access to internal networks.
You can configure the firewall to put controls on access to the Internet from the
protected networks and to allow controlled access to internal networks.
