Active User (Public Preview)

The Active User feature assists security administrators quickly identify and assign recommendations to the most relevant users based on recent control plane activity. For each recommendation, up to three potential active users are suggested at the resource, resource group, or subscription level. Administrators can select a user from the list, assign the recommendation, and set a due date—triggering a notification to the assigned user. This streamlines remediation workflows, reduces investigation time, and strengthens overall security posture.

Update to Defender for SQL servers on Machines plan

April 28, 2025

The Defender for SQL Server on machines plan in Microsoft Defender for Cloud protects SQL Server instances hosted on Azure, AWS, GCP, and on-premises machines.

Starting today, we're gradually releasing an enhanced agent solution for the plan. The agent-based solution eliminates the need to deploy the Azure Monitor Agent (AMA) and instead uses the existing SQL infrastructure. The solution is designed to make the onboarding processes easier and improve protection coverage.

Required customer actions

  1. Update Defender for SQL Servers on Machines plan configuration: Customers who enabled Defender for SQL Server on machines plan before today are required to follow these instructions to update their configuration, following the enhanced agent release.

  2. Verify SQL Server instances protection status: With an estimated starting date of May 2025, customers must verify the protection status of their SQL Server instances across their environments. Learn how to troubleshoot any deployment issues Defender for SQL on machines configuration.

Note

After the agent upgrade occurs, you might experience a billing increase if additional SQL Server instances are protected with your enabled Defender for SQL Servers on Machines plan. For billing information, review the Defender for Cloud pricing page.

Enhancements for Defender for app service alerts

April 7, 2025

On April 30, 2025, Defender for App Service alerting capabilities will be enhanced. We'll add alerts for suspicious code executions and access to internal or remote endpoints. Additionally, we have improved coverage and reduced noise from relevant alerts by expanding our logic and removing alerts that were causing unnecessary noise. As part of this process, the alert "Suspicious WordPress theme invocation detected" will be deprecated.

Upcoming change to the recommendation severity levels

March 11, 2025

We're enhancing the severity levels of recommendations to improve risk assessment and prioritization. As part of this update, we reevaluated all severity classifications and introduced a new level — Critical. Previously, recommendations were categorized into three levels: Low, Medium, and High. With this update, there are now four distinct levels: Low, Medium, High, and Critical, providing a more granular risk evaluation to help customers focus on the most urgent security issues.

As a result, customers might notice changes in the severity of existing recommendations. Additionally, the risk level evaluation, which is available for Defender CSPM customers only, might also be affected as both recommendation severity and asset context are taken into consideration. These adjustments could affect the overall risk level.

The projected change will take place on March 25, 2025.

Important

The availability of File Integrity Monitoring in Azure China 21Vianet and in GCCM clouds is not currently planned to be supported.
