[Introduction]
We're excited to announce performance and usability improvements to the DLP Alerts Page in Microsoft Purview Portal to help you triage incidents faster and more efficiently.
🚀 What's New:
Unified View: Events related to each alert are now available directly on the alerts page - no need to switch to new tab or drill down.
Faster Access: Access event details (e.g. Impacted assets) with just one click on the main alerts page itself, compared to four clicks earlier, reducing triage time significantly.
Enhanced Context: We've added four new columns - Location, DLP policy name, DLP rule name, and Rule action to display key alert and event attributes upfront - giving you more visibility at a glance.
Performance Boost: Cache improvements to ensure faster load times and a smoother experience.
These updates are designed to streamline your workflow, reduce response times, and give you the context you need - all in a single, efficient view.

explanation for non-techies**

Microsoft has introduced updates to the Data Loss Prevention (DLP) Alerts page in the Purview Portal, which are designed to make managing and responding to alerts more efficient. Imagine the DLP Alerts page as a control center where you can monitor and manage potential data breaches or leaks. Previously, getting the information you needed was like having to open multiple drawers in a filing cabinet to find a single document. Now, with these updates, it's like having all the necessary documents laid out on a desk in front of you, making it much quicker to find what you need.

The key improvements include a unified view where all events related to an alert are visible directly on the main page. This is akin to having a summary of all related documents in one place, rather than having to go to different sections to gather the full picture. Additionally, accessing event details now requires just one click instead of four, which is like having a shortcut that takes you directly to the needed information without unnecessary steps.

Four new columns have been added to provide more context at a glance: Location, DLP policy name, DLP rule name, and Rule action. Think of these columns as labels on folders that tell you exactly what's inside without having to open them. This added visibility helps in understanding the situation quickly.

The performance of the page has also been improved, meaning it loads faster and runs more smoothly. This is similar to upgrading from a slow computer to a faster one, making your work more efficient and less frustrating.

These changes will start rolling out in late September 2025, with general availability expected by early November 2025. No action is required from administrators for these updates, as they will be applied automatically. The goal of these improvements is to streamline workflows, reduce response times, and provide all necessary information in a single, efficient view.
