Prerequisites
Before you begin, make sure you have:
- Microsoft Intune admin access (requires Microsoft 365 E3/E5 or Intune standalone license)
- Azure AD with devices enrolled in Intune
- PromptDuty License Key β available in your admin dashboard
This deployment typically takes 10-15 minutes to configure and 1-4 hours to propagate to all devices.
Deploy to Microsoft Edge
Microsoft Edge policies can be configured directly through Intune's Settings Catalog.
Open Microsoft Intune Admin Center
Navigate to intune.microsoft.com and sign in with your admin credentials.
Create a Configuration Profile
Go to Devices β Configuration profiles β Create profile
- Platform: Windows 10 and later
- Profile type: Settings catalog
Add Edge Extension Settings
Click Add settings and search for "Edge" β select Microsoft Edge β Extensions
Enable the following setting:
- Control which extensions are installed silently
Configure the Extension
Add the PromptDuty extension using this format:
mbnljgkelbgppmhafiicodplhkelappd;https://clients2.google.com/service/update2/crx
This Extension ID points to the Chrome Web Store, which also works for Edge via Chromium compatibility.
Assign to Groups
Under Assignments, select the Azure AD groups that should receive the extension. You can target:
- All users
- All devices
- Specific security groups
Review and Create
Review your settings and click Create. The policy will begin deploying to targeted devices.
Deploy to Google Chrome
Chrome extension deployment through Intune uses ADMX templates.
Create a New Configuration Profile
Go to Devices β Configuration profiles β Create profile
- Platform: Windows 10 and later
- Profile type: Templates β Administrative Templates
Import Chrome ADMX (if not already imported)
If you haven't imported Chrome ADMX templates, download them from Google Chrome Enterprise.
Go to Devices β Configuration profiles β Import ADMX and upload the Chrome templates.
Configure Force-Installed Extensions
Navigate to: Computer Configuration β Google β Google Chrome β Extensions
Enable: Configure the list of force-installed apps and extensions
mbnljgkelbgppmhafiicodplhkelappd;https://clients2.google.com/service/update2/crx
Assign and Deploy
Assign the profile to your target groups and create the policy.
Configure License Key
To pre-configure the license key so users don't need to enter it manually, you can use managed storage policies.
Get Your License Key
Copy your license key from the PromptDuty dashboard.
Create Extension Policy
In Intune, create a custom OMA-URI policy with the following configuration:
./Device/Vendor/MSFT/Policy/Config/Chrome~Policy~googlechrome~Extensions/ExtensionSettings
{
"mbnljgkelbgppmhafiicodplhkelappd": {
"installation_mode": "force_installed",
"update_url": "https://clients2.google.com/service/update2/crx",
"managed_configuration": {
"licenseKey": "YOUR_LICENSE_KEY_HERE"
}
}
}
The license key should only be accessible to IT administrators. Users with the extension will have it pre-configured automatically.
Verify Installation
After deployment, verify the extension is installed correctly:
Check Browser Extensions
On a target device, open Edge or Chrome and go to the extensions page:
- Edge:
edge://extensions - Chrome:
chrome://extensions
You should see PromptDuty listed as "Installed by your organization".
Test the Extension
Navigate to ChatGPT, Claude, or another AI tool and try typing a test prompt with sample PII (e.g., "John Doe's SSN is 123-45-6789"). You should see PromptDuty's warning appear.
Once verified, the extension will automatically protect all AI interactions across your organization.
Troubleshooting
Extension not appearing on devices
- Wait up to 4 hours for Intune policies to sync
- Force a sync: Settings β Accounts β Access work or school β Info β Sync
- Verify the device is enrolled in Intune
Extension installed but not working
- Check that the license key is correctly configured
- Verify your organization's subscription is active in the PromptDuty dashboard
