explanation for non-techies**

Microsoft Purview is rolling out a new feature to help security teams manage data loss prevention (DLP) alerts more effectively. Think of this feature like sorting your emails into folders based on their importance or relevance. Just as you might label an email as "important," "spam," or "personal," this new feature allows you to classify DLP alerts as True Positive, False Positive, Benign Positive, or Not Set.

This classification helps in organizing and prioritizing alerts, making it easier for admins to handle them. Imagine if you had a pile of documents on your desk, and you could instantly sort them into categories like "urgent," "review later," or "ignore." This is similar to what the new classification property does for DLP alerts.

The classifications sync between Microsoft Purview and Microsoft Defender, much like how your phone and computer might sync contacts or calendar events. This means that any changes you make in one place will automatically update in the other, ensuring consistency and saving time.

Admins can apply these classifications individually or to multiple alerts at once, similar to how you might select multiple files on your computer and move them to a folder in one go. This bulk action capability is particularly useful for managing large volumes of alerts efficiently.

The feature will be available by default, so there's no need for any setup or activation. It's like buying a new car that comes with built-in GPS; you can start using it right away without any additional installation.

Overall, this new feature aims to streamline the process of managing DLP alerts, making it easier for security teams to focus on what truly matters and respond to incidents more effectively.
