Question details

The user needs to understand whether to use the Azure Information Protection (AIP) scanner or the AIP client for discovering and labeling documents stored on Windows web servers.

AIP Scanner vs. AIP Client for Document Discovery on Servers
Product
Azure Information Protection (AIP)
Device & OS
Windows Server
Scenario
Automating the discovery and protection of documents located in repositories on Windows web servers.
Observed behavior
Confusion regarding the proper deployment strategy, specifically whether installing the AIP client on a web server can replace scanner-based repository discovery.
Before you start

Verify that your Windows servers expose supported repositories like shared folders (SMB) and ensure you have the appropriate administrative permissions for Microsoft Purview or Azure Information Protection.

Solution 1Recommended

Deploy the AIP Scanner for Server Repositories

Use the AIP scanner for automated server-side document discovery instead of the AIP client, which is designed exclusively for interactive end-user labeling.

The AIP scanner and AIP client serve entirely different purposes. The AIP scanner is designed to operate from a central server to automatically scan, discover, and label data at rest in network repositories such as file shares and SharePoint locations.

In contrast, the AIP client is built for end-user computers to allow individuals to manually classify and protect documents. Installing the AIP client on a Windows web server will not function as a replacement for automated repository discovery.

1
Evaluate Server Repositories

Review your Windows web servers to determine if they currently expose shared folders or other supported on-premises repositories.

2
Configure Accessible File Shares

If your web servers do not expose supported repositories, configure an accessible network file share (SMB) so that the central AIP scanner can reach and scan the stored documents.

3
Review Purview Scanning Options

Log into the Microsoft Purview compliance portal to deploy and configure the AIP scanner node, pointing it to the newly configured file shares for automated discovery.

Frequently Asked Questions

Can I use the AIP client on a Windows Server to automatically scan local documents?

No, the AIP client is designed strictly for interactive use on end-user computers. To automate scanning and labeling of documents on server repositories, you must deploy the AIP scanner.

What types of repositories can the AIP scanner discover?

The AIP scanner is designed to discover, classify, and protect documents stored in on-premises network file shares (using SMB protocols) and SharePoint Server document libraries.

Is the AIP scanner included with Microsoft Purview?

Yes, the AIP scanner functionality is integrated into Microsoft Purview Information Protection, allowing you to extend your cloud-based labeling policies to on-premises data stores.

How should end-users protect their documents interactively?

End-users should protect documents interactively by installing the AIP client (or using the built-in sensitivity labels in modern Office apps) directly on their personal Windows desktops or laptops.
