@Vernham, Kyle William - Thanks for the question and using MS Q&A platform.
Microsoft Purview comes with multiple pretrained classifiers. They appear in the Microsoft Purview compliance portal > Data classification > Trainable classifiers view with the status of
Ready to use.
Optical character recognition (OCR) scanning enables Microsoft Purview to scan content in images for sensitive information. An optional feature, OCR scanning is first enabled at the tenant level. Once enabled, you select the locations where you want to scan images. Image scanning is available for Exchange, SharePoint, OneDrive, Teams, and Windows devices. Once the OCR settings are configured, your existing policies for data loss prevention (DLP), records management, and insider risk management (IRM) are applied to images and text-based content.
For more details, refer to Trainable classifiers definitions and Learn about optical character recognition in Microsoft Purview.
