Branding

The Branding section lets you customize how Check looks, especially useful for organizations that want consistent branding.

For individual users

Most individual users can skip this section unless they want to personalize the extension.

Overview

All user-facing components (suspicious login banner, blocked page, extension popup, and options page) use the same branding configuration. Your custom branding will be displayed consistently across:

• Suspicious Login Banner - Warning banner shown on potentially malicious sites

• Blocked Page - Full-page block screen for confirmed threats

• Extension Popup - Extension icon popup

• Options Page - Extension settings page

Company Information

What if Settings Are Not Visible?

If some settings do not appear on your version, it means your organization's IT department has set these for you. This is normal in business environments - your IT team wants to make sure everyone has the same security settings. You will also see text indicating that the extension is being managed by policy.

Branding Properties

You can customize the following properties:

1. Company Name - Enter your organization's name. This appears in the extension interface and blocked page messages (displayed as "Protected by [Company Name]").

2. Company URL - Your company website URL (e.g., https://yourcompany.com). Used in extension branding and contact information. (Firefox: required, Chrome/Edge: optional)

3. Product Name - What you want to call the extension (like "Contoso Security" instead of "Check"). This replaces the default "Check" branding throughout the interface.

4. Support Email - Where users should go for help. This email address is used in the "Contact Admin" button when phishing sites are blocked.

Visual Customization

1. Primary Color - Choose a color that matches your brand (hex format, e.g., #FF5733). This color is applied to buttons, headers, and other interface elements throughout the extension.

2. Logo URL - Link to your company logo or local path (e.g., https://cdn.example.com/logo.png or images/custom-logo.png). This replaces the default Check logo in the extension popup, options page, and blocked page warnings.

Live Preview

The branding preview shows you exactly how your customizations will appear to users. Changes are reflected immediately as you modify the settings, showing:

• Your custom logo and company name in the header

• How the primary color affects buttons and interface elements

• The overall visual appearance users will see

Configuration Methods

Method 2: Group Policy (GPO) - Chrome & Edge

For enterprise deployments using Windows Group Policy:

1. Create a new GPO or edit an existing one

  }
}

2. The extension will automatically use the enterprise branding on managed devices

Method 3: Firefox Policies (policies.json)

Works with: Firefox only

For Firefox deployments, configure branding through the policies.json file:

1. Locate or create the policies file:

   • Windows: %ProgramFiles%\Mozilla Firefox\distribution\policies.json

   • macOS: /Applications/Firefox.app/Contents/Resources/distribution/policies.json

   • Linux: /etc/firefox/policies/policies.json

2. Add the branding configuration under 3rdparty.Extensions:

{
  "policies": {
    "3rdparty": {
      "Extensions": {
        "[email protected]": {
          "customBranding": {
            "companyName": "Your Company",

            "logoUrl": "https://example.com/logo.png"
          }
        }
      }
    }
  }
}

1. Save the file and restart Firefox

Note: The Firefox extension ID is [email protected]

Method 4: Microsoft Intune - Chrome & Edge

For organizations using Microsoft Intune with Chrome/Edge:

1. Create a new Configuration Profile

2. Select "Custom" configuration

3. Add the branding configuration as a JSON payload:

{
  "customBranding": {
    "companyName": "Your Company",
    "logoUrl": "https://example.com/logo.png",
    "primaryColor": "#FF5733",
    "supportEmail": "[email protected]"
  }
}

1. Assign the profile to user or device groups

2. Branding will be applied on enrolled devices

Method 5: Chrome Enterprise Policy

For Chrome Enterprise customers:

1. Access the Google Admin Console

2. Navigate to: Devices > Chrome > Apps & Extensions

3. Select the Check extension

4. Add the branding configuration under "Policy for extensions"

5. Save and publish the policy

Method 6: Windows Registry (Advanced) - Chrome & Edge

For direct registry configuration with Chrome/Edge:

1. Open Registry Editor

2. Navigate to: HKLM\Software\Policies\Google\Chrome\3rdparty\extensions\[extension-id]

3. Create a new key named customBranding

4. Add string values for each branding property

5. Restart the browser

Configuration Priority

When multiple configuration methods are used, they are applied in this order (highest to lowest priority):

1. Enterprise Policy (GPO/Intune/Chrome Enterprise/Firefox Policies)

2. Manual Configuration (Options page)

3. Default Configuration (Built-in defaults)

Enterprise policies always take precedence over manual settings.

Logo Requirements and Tips

Technical requirements:

• Format: PNG, JPG, or SVG

• Size: 48x48 pixels recommended (maximum 128x128, recommended 200x200px or smaller for enterprise deployments)

• Must be accessible via HTTPS URL

Design tips:

• Use a square logo for best results

• Ensure it looks good on both light and dark backgrounds

• Keep it simple - small logos need to be clear

Common logo hosting options:

• Your company website: https://yourcompany.com/logo.png

• Cloud storage: Upload to Google Drive, Dropbox, etc. and get a public link

• Image hosting: Use services like Imgur or similar

Browser-Specific Notes

Firefox

• Uses extension ID: [email protected]

• Configuration is managed through policies.json file

• Supports additional companyURL property

• Policies file location varies by operating system

Chrome & Edge

• Configuration through GPO, Intune, or Chrome Enterprise Policy

• Uses Windows Registry for advanced configurations

• Supports standard Chrome extension policy format

Troubleshooting Branding Issues

Logo not showing:

1. Check that the URL is correct and accessible

2. Try opening the logo URL in a new browser tab

3. Make sure the URL starts with https://

4. Verify the image file isn't too large

5. Verify logo URLs are publicly accessible (if using external URL)

6. Check image format (PNG, JPG, SVG supported)

7. Ensure image size is reasonable

Colors not applying:

1. Make sure you clicked "Save Settings"

2. Try refreshing the page

3. Check if your organization has locked branding settings

Branding Not Appearing
