Note

The Microsoft Purview extension for Chrome is only applicable to Windows devices. The extension is not necessary for the enforcement of data loss prevention on macOS devices.

Before you begin

To use the Microsoft Purview extension for Chrome, the device must be onboarded into Endpoint data loss prevention (DLP). Review these articles if you're new to DLP or Endpoint DLP:

SKU/subscriptions licensing

Before you get started, you should confirm your Microsoft 365 subscription and any add-ons. To access and use the Endpoint DLP functionality, you must have one of the following subscriptions or add-ons:

Microsoft 365 E5
Microsoft 365 A5 (EDU)
Microsoft 365 E5 compliance
Microsoft 365 A5 compliance
Microsoft 365 E5 information protection and governance
Microsoft 365 A5 information protection and governance

For detailed licensing guidance, see Microsoft 365 licensing guidance for security & compliance.

Your organization must be licensed for Endpoint DLP.
Your devices must be running Windows 10 x64 (build 1809 or later).
The device must have Antimalware Client version 4.18.2202.x or later. Check your current version by opening the Windows Security app, select the Settings icon, and then select About.

Permissions

Data from Endpoint DLP can be viewed in Activity explorer. There are seven roles that grant permission to view and interact with activity explorer. The account you use for accessing the data must be a member of at least one of them.

Global administrator
Compliance admin
Security admin
Compliance data admin
Global reader
Security reader
Reports reader

Important

Microsoft recommends that you use roles with the fewest permissions. This helps improve security for your organization. Global Administrator is a highly privileged role that should only be used in scenarios where a lesser privileged role can't be used.

Roles and Role Groups

There are roles and role groups that you can use to fine tune your access controls.

Here's a list of applicable roles. To learn more about them, see Permissions in the Microsoft Purview compliance portal.

Information Protection Admin
Information Protection Analyst
Information Protection Investigator
Information Protection Reader

Overall installation workflow

Deploying the extension is a multi-phase process. You can choose to install it on one machine at a time, or you can use Microsoft Intune or Group Policy for organization-wide deployments.

Prepare infrastructure

If you're rolling out the extension to all your monitored Windows 10/11 devices, you should remove Google Chrome from the unallowed app and unallowed browser lists. For more information, see Unallowed browsers. If you're only rolling it out to a few devices, you can leave Chrome on the unallowed browser or unallowed app lists. The extension bypasses the restrictions of both lists for those computers where it's installed.

Prepare your devices

Use the procedures in these articles to onboard your devices:

Important

Microsoft Purview has upgraded Purview Chrome extension Manifest V3. If you already have Purview Chrome extension installed, you should see automatic upgrade on your machine to 3.0.0.239 or higher.

Basic Setup Single Machine Selfhost

This is the recommended method.

Navigate to Microsoft Purview Extension - Chrome Web Store (google.com).
Install the extension using the instructions on the Chrome Web Store page.

Deploy using Microsoft Intune

Use this setup method for organization-wide deployments.

Microsoft Intune Force Install Steps

Using the settings catalog, follow these steps to manage Chrome extensions:

Sign in to the Microsoft Intune admin center.
Navigate to Configuration Profiles.
Select Create Profile.
Select Windows 10 and later as the platform.
Select Settings catalog as the profile type.
Select Custom as the template name.
Select Create.
Enter a name and optional description on the Basics tab and select Next.
Select Add settings on the Configuration settings tab.
Select Google > Google Chrome > Extensions.
Select Configure the list of force-installed apps and extensions.
Change the toggle to Enabled.
Enter the following value for the extensions and app IDs and update URL: echcggldkblhodogklpincgchnpgcdco;https://clients2.google.com/service/update2/crx.
Select Next.
Add or edit scope tags on the Scope tags tab as needed and select Next.
Add the required deployment users, devices, and groups on the Assignments tab and select Next.
Add applicability rules on the Applicability Rules tab as required and select Next.
Select Create.

Deploy using Group Policy

If you don't want to use Microsoft Intune, you can use group policies to deploy the extension across your organization.

Adding the Chrome Extension to the ForceInstall List

In the Group Policy Management Editor, navigate to your OU.
Expand the following path Computer/User configuration > Policies > Administrative templates > Classic administrative templates > Google > Google Chrome > Extensions. This path may vary depending on your configuration.
Select Configure the list of force-installed extensions.
Right click and select Edit.
Select Enabled.
Select Show.
Under Value, add the following entry: echcggldkblhodogklpincgchnpgcdco;https://clients2.google.com/service/update2/crx
Select OK and then Apply.

Test the Extension

Upload to cloud service, or access by unallowed browsers Cloud Egress

Create or get a sensitive item and try to upload a file to one of your organization’s restricted service domains. The sensitive data must match one of our built-in Sensitive Info Types, or one of your organization’s sensitive information types. You should get a DLP toast notification on the device you're testing from that shows that this action isn't allowed when the file is open.

Simulate other DLP scenarios in Chrome

Now that you’ve removed Chrome from the disallowed browsers/apps list, you can run simulation scenarios below to confirm that the behavior meets your organization’s requirements:

Copy data from a sensitive item to another document using the Clipboard
- To test, open a file that is protected against copy to clipboard actions in the Chrome browser and attempt to copy data from the file.
- Expected Result: A DLP toast notification showing that this action isn't allowed when the file is open.
Print a document
- To test, open a file that is protected against print actions in the Chrome browser and attempt to print the file.
- Expected Result: A DLP toast notification showing that this action isn't allowed when the file is open.
Copy to USB Removable Media
- To test, try to save the file to a removable media storage.
- Expected Result: A DLP toast notification showing that this action isn't allowed when the file is open.
Copy to Network Share
- To test, try to save the file to a network share.
- Expected Result: A DLP toast notification showing that this action isn't allowed when the file is open.

Use the Alerts Management Dashboard to view Chrome DLP alerts

Open the Data loss prevention page in the Microsoft Purview compliance portal and select Alerts.
Refer to the procedures in Get started with the data loss prevention Alerts dashboard and Investigate data loss incidents with Microsoft Defender XDR to view alerts for your Endpoint DLP policies.

Viewing Chrome DLP data in activity explorer

Open the Data classification page for your domain in the Microsoft Purview compliance portal and choose Activity explorer.
Refer to the procedures in Get started with Activity explorer to access and filter all the data for your Endpoint devices.

Known Issues and Limitations

Incognito mode isn't supported and must be disabled.

Next steps

Now that you have onboarded devices and can view the activity data in Activity explorer, you're ready to move on to your next step where you create DLP policies that protect your sensitive items.
