How Defender XDR Automation Works
Automated Investigation and Response
You can use Defender XDR Automation to transform your security operations. Automated investigation and response (AIR) helps you handle threats at scale. When Defender XDR detects suspicious activities, it launches an automated investigation. The system collects evidence, analyzes indicators of compromise, and determines the best automated response actions. You see the results in the Microsoft Defender portal, where you can track the status and review each step.
Automation rules play a key role in this process. You can set automation rules to trigger specific actions when high-fidelity alerts appear. For example, you might want to quarantine a device, block a file, or add actions to close the incident. These automation rules help you respond faster and reduce manual work. You can also use advanced hunting to search for threats across your environment and trigger automated device vulnerability management when you find a risk.
Automated investigation and response deliver measurable results:
42% reduction in security operations staff hours
20% decrease in general IT security project hours
Up to 254% return on investment
Faster incident response through automated correlation and containment
You can track key metrics like Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR) in your dashboards. These metrics show how automation rules and automated response actions improve your security posture. By using AIR, you can manage thousands of endpoints and respond to threats in seconds, not hours.
Device Groups and Remediation Levels
Device groups and remediation levels give you control over how automation works in your environment. You can organize devices into groups based on attributes like device name, domain, operating system, or tags. This structure works much like Organizational Units. Each device group can have its own remediation automation settings. You decide if you want full automatic remediation, semi-automated approval, or manual intervention.
When you create a device group, you set the automation level. For example, you might want full automation for laptops but require approval for servers. Automation rules apply to each group based on its remediation level. If a device matches more than one group, Defender XDR uses the highest-ranked group. This ranking ensures that only one set of automation rules and remediation settings applies to each device.
Tip: Regularly review your device groups and remediation levels. Remove unused groups and adjust automation rules to match your current security needs.
This approach supports automated device vulnerability management. You can target specific device groups with automation rules to address critical vulnerabilities quickly. The system helps you prioritize and remediate vulnerabilities, reducing risk across your organization. A strong vulnerability management solution relies on well-defined device groups and clear remediation levels.
You can scale this setup as your organization grows. Defender XDR supports centralized management, role-based access control, and integration with multi-cloud environments. You can manage incident management and vulnerability management solution tasks from a single interface, making it easier to protect your assets.
Balancing Automation and Human Oversight
Automation rules and AIR handle many routine tasks, but you still need human oversight for complex threats. Defender XDR lets you balance automation with analyst review. You can set automation rules to require approval for certain actions, especially when dealing with critical vulnerabilities or sensitive systems.
This balance reduces false positives. AI and machine learning enrich alerts with context, but human analysts provide judgment and situational awareness. You can use advanced hunting to investigate indicators of compromise that automation might miss. Analysts can review automated investigations, validate findings, and adjust automation rules as needed.
A tiered approach works best:
Low-risk, high-confidence alerts can be closed automatically.
Medium-risk alerts trigger automated evidence gathering, but analysts verify the results.
High-risk or complex incidents require full analyst review before automated response actions occur.
Note: Continuous feedback and regular audits help you refine automation rules and improve your vulnerability management solution.
By combining automation rules, advanced hunting, and human expertise, you create a robust incident management process. You can respond to threats faster, reduce manual errors, and focus your team on the most important tasks. Defender XDR Automation empowers you to manage vulnerability, indicators of compromise, and suspicious activities with confidence.
