Enforcing Safe Search for Linewize Appliances

This article is for IT support with a Linewize appliance.

Safe Search is a service run by Microsoft and Google to remove mature content from search results in Bing, Google Search, and YouTube Search. You can configure your Linewize appliance to enforce Safe Search.


We recommend installing Linewize Connect, whenever possible to reduce the load on your appliance and have the user’s local device enforce Safe Search.


It's important to avoid double inspecting. Double inspecting occurs when multiple Safe Search options are active simultaneously. This can happen when two or more of these scenarios is true:

  1. Your school's firewall has Safe Search enabled.
  2. Your school's Google Workspace has Safe Search enabled.
  3. Your School Manager physical appliance has Safe Search enabled.
  4. Your Connect for Chrome, Windows, macOS, and iOS devices have Safe Search enabled.

To prevent double inspecting, remember to turn off the other Safe Search options when one is in use. This practice ensures Safe Search works correctly and blocks explicit and potentially offensive content from appearing on Google, Bing, and YouTube searches.

Before You Start

  • You can segment your Safe Search configuration into custom Safe Search profiles, if you need different search access by groups. You can identify a range of IP addresses, the subnet for a group of devices or create Object Pools with MAC addresses or IP addresses.
  • Consider the YouTube filter mode set for your school. If your school sets YouTube into strict search mode, teachers cannot override this in Classwize.

Enabling Safe Search

  1. Go to Filtering > Safe Search.
  2. Select Add Policy.
  3. Click Select Criteria in Groups and Devices and then add the identity of the users or devices.
User Pick a single user name from a list
Group Pick a list name from your predefined Groups
Network Range Type the starting and ending IP addresses for a range of devices
Network Type IP address and subnet mask for a group of devices
IP Address Type a single IP address
IP Address Object Select one of your pre-configured Pools of IP Addresses
MAC Address Type the MAC address of a single device
MAC Address Object Select one of your pre-configured Pools of MAC addresses



Leave the Criteria blank if you want to apply the Safe Search configuration to all users.

  1. Select Enforced in Google Safe Search to enforce age-appropriate Google Search results (websites and images).
  2. Select a fair use category from the Usage Rights list for images students might copy from a Google Image Search.


Select Not filtered by license if you want all images displayed, regardless of the fair usage rights associated with the image.

You can visit the International Press Telecommunications Council (IPTC) “Web Statement of Rights” tracked in Google Image Search.

  1. To enforce age-appropriate video results, select Moderate or Strict in YouTube Safe Search.
    1. Strict mode blocks videos, comments, recommendations, and YouTube search results based on School Manager’s filtering categories for the most sensitive viewers.
    2. Moderate mode adds some limited access topics appropriate for older students who need legitimate access to topics such as war history, social issues or human biology.
  2. To enforce age-appropriate search results in Bing, select Enforced in Bing Safe Search.
  3. Select Save Policy.

Repeat the steps if you need to create different Safe Search criteria for a separate group of users or devices.
