Next, we’ll look at the latest enhancement to Defender for Endpoint P2—enhanced automated remediation through AIR, currently in Private Preview.

Microsoft continues to raise the bar for endpoint security by enhancing the automation capabilities within Defender for Endpoint Plan 2 (P2). The latest improvements to Automated Investigation and Response (AIR) are designed to reduce response time, lower analyst workload, and contain threats before they can spread laterally within your organization.

Traditionally, responding to endpoint alerts—especially across a large fleet—meant manually reviewing each incident and executing remediation steps such as killing processes, quarantining files, or removing registry entries. With Defender for Endpoint’s AIR, these actions are now intelligently automated. When a threat is detected, AIR initiates an investigation that collects forensic evidence, determines threat confidence, and—if confidence is high—executes remediation actions automatically without requiring analyst approval.

AIR uses contextual signals and correlation from Microsoft Threat Intelligence to determine root cause and scope of impact, allowing it to remediate not just symptoms (e.g., malware files), but also persistence mechanisms and related artifacts. These actions can include:

• Stopping malicious processes
• Deleting or quarantining malicious files
• Removing scheduled tasks, services, and registry keys
• Containing the device if the threat is deemed high-severity

All actions are fully auditable through the Action Center, and investigations are transparently documented with timelines and outcomes. This ensures that security teams maintain visibility and control over automated workflows while benefiting from reduced manual overhead.

The operational payoff is clear: routine threats are remediated within minutes rather than hours, freeing analysts to focus on strategic threat hunting and complex investigations. For environments managing hundreds or thousands of endpoints, AIR is a force multiplier—especially in resource-constrained organizations like schools, public sector entities, and mid-sized enterprises experiencing fast growth and evolving threat landscapes.

Up next, we’ll explore how Defender for Endpoint P2 integrates these automation capabilities into broader security operations—streamlining collaboration with Microsoft Sentinel, Microsoft Purview, and identity protection features within Entra.
