If you enable Safe Search Enforcement, the default
behavior of the firewall is to block search results for end users
searching on Bing, Yahoo, Yandex, or Youtube search engines until
they set their safe search setting to the strictest available option.
By default, the URL filtering safe search block page displays in
their browser. The
predefined block page provides
a link to the search settings for the search engine used, so that
users can adjust the safe search setting. You can
customize the safe
search block page to meet your organization’s specific needs.
