Disabling Google Safe Browsing Warning Message Using Group Policy

  • Last updated on

Google Safe Browsing is designed to protect people from visiting suspicious-looking sites. Barracuda PhishLine landing pages are benign, but are designed to look suspicious, so they are often flagged by Google Safe Browsing. Google Chrome then displays a potential phishing warning page to your users. 

The procedures described in this article enable your organization to use group policy to add domains used in your campaigns to an allow list and prevent Google Chrome from displaying the warning page to your users.

For full details, consult the complete Google Chrome Group Policy documentation


  • These procedures are described with the assumption that you are already familiar with using group policy to manage Windows and Mac PCs. If you are not already familiar with group policy, work with your IT staff to set up and distribute this policy.
  • These procedures are for the older ADM template files. If your organization uses the newer ADMX files, they are also included in the ZIP file downloaded in Step 1.

  • If your organization does not implement Group Policy, you can still implement the Google Safe Browsing allow list through Chrome Managed Browsers, as described in the Google link above.

To create a safe browsing template:

Create the New Group Policy
  1. Download the Chrome Dev Policy Template from the Google support website. This is separate from the browser download. 
  2. Extract the downloaded ZIP file to a temporary directory on the domain controller server or group policy workstation.
  3. On your PC, open the Group Policy Manager.
  4. Create new Group Policy named Barracuda Chrome Allow List.
  5. Edit the new policy, following directions in the next section. 
Import the Chrome Group Policy Template 

Steps 1-6 in this section are performed only once.

  1. In the Group Policy Manager, locate Computer Configuration.
  2. Right-click on Administrative Templates and select Add/Remove Templates.
  3. Click Add
  4. Navigate to folder you created in the temporary directory in step 2 in the section above. Within that folder, navigate to windows\adm\en-US.
  5. Select the chrome.adm file and click Open.
  6. In the Add/Remove Templates window, click Close.

  7. Back in the Administrative Templates folder, navigate to Classic Administrative Templates (ADM)>Google>Google Chrome->Safe Browsing settings.
  8. Double-click on Configure the list of domains on which Safe Browsing will not trigger warnings.
  9. In the new window, select Enabled
  10. In the Options box, click Show
  11. In the Show Contents window that appears, enter the list of domains you will be using in your campaign, then click OK
  12. Click OK to apply your changes and close the Configure the list of domains... window.
  13. Exit the Group Policy Management Editor.
Linking and Applying Policies

Use your organization's usual procedures to link the policy to the correct organizational unit(s) and push out the group policy.

Affect on Email and SMS Campaigns

After you set up your group policy, you can select the  Allow Domains on Block Lists option in your campaigns that use email.  Even if your domains are block listed, your new group policy will allow users to click through without seeing the Google Safe Browsing warning screen. 

For details refer to Creating and Generating an Email Campaign as well as creating and running an Automated Campaign, a Benchmark Campaign, and a Training Campaign.
