Content block
Control web content by blocking specific words or patterns. If enabled in the
protection profile, the FortiGate unit searches for words or patterns in on
requested web pages. If matches are found, values assigned to the words are
totalled. If a user-defined threshold value is exceeded, the web page is blocked
Use Perl regular expressions or wildcards to add banned word patterns to the list.
Note: Perl regular expression patterns are case sensitive for Web Filter content block. To
make a word or phrase case insensitive, use the regular expression /i. For example,
/bad language/i blocks all instances of bad language regardless of case. Wildcard
patterns are not case sensitive.
