Google provides servers that
Lock SafeSearch
(forcesafesearch.google.com) settings in every Google and YouTube
search. By adding a DNS entry for
www.google.com
and
www.youtube.com
(and other relevant
Google and YouTube country subdomains) that includes a CNAME record
pointing to
forcesafesearch.google.com
to
your DNS server configuration, you can ensure that all users on your
network are using strict safe search settings every time they
perform a Google or YouTube search. Keep in mind, however, that this
solution is not compatible with Safe Search Enforcement on the
firewall. Therefore, if you are using this option to force safe
search on Google, the best practice is to block access to other
search engines on the firewall by creating custom URL categories and
adding them to the block list in the URL Filtering profile.
