This article explains how to enforce SafeSearch across all major search engines in order to help prevent unsuitable content from being presented to the user.


Many search engines provide some form of SafeSearch which when enabled aims to prevent unsuitable content from appearing in the search results. Guardian can force the use of SafeSearch on many services including Google™, Yahoo!®, Bing® and ASK™

This article will help you set up your content modification policies so that they are effective across all supported search engines.


Smoothwall provides two content modification policies to enforce SafeSearch.

Force SafeSearch

The first content modification policy is named Force SafeSearch. This policy requires a HTTPS Decrypt and Inspect policy to be most effective. If you cannot or do not wish to employ a HTTPS Decrypt and Inspect policy then Guardian will not be able to enforce SafeSearch for any search engine which uses HTTPS.

To set up the Force SafeSearch content modification policy do the following:

At this point you should find that SafeSearch is enforced across all major search engines. Any attempts to disable SafeSearch will fail and it will automatically be re-enabled by Guardian.

SafeSearch via CONNECT header

The second content modification policy is named SafeSearch via CONNECT header. This policy does not require a HTTPS Decrypt and Inspect policy to work but will only enforce SafeSearch for the below services:

  • Google Search Engine
  • Bing Search Engine
  • Pixabay Image Search Engine

To set up the SafeSearch via CONNECT header content modification policy do the following:
