Microsoft has announced a new Library Management feature in Microsoft Defender for Endpoint, aiming to enhance the management of scripts and tools for security analysts during live response investigations.
Microsoft has announced a new Library Management feature in Microsoft Defender for Endpoint, aiming to enhance the management of scripts and tools for security analysts during live response investigations.
Released on Fri, Feb 16, 2026, this update resolves the issue of having to upload scripts and executables during active sessions, which previously slowed incident response and hindered consistency across teams.
The new Library Management feature provides a proactive and efficient way to manage investigation assets, improving operational readiness, visibility, and control. This enhancement streamlines response workflows for security operations center (SOC) teams.
Centralized Management — Security teams can upload, manage, and organize Live Response scripts and files outside active investigations, enhancing preparation and alignment. Pre-staged Uploads — PowerShell scripts, batch files, and other tools can be uploaded in advance for immediate access during critical investigations. In-portal Script Viewing — Analysts can review script logic directly within the Defender user interface, eliminating the need for external tools. Library Organization — Outdated or redundant scripts can be easily deleted to maintain a lean and audit-ready library.
This enhancement streamlines response workflows for security operations center (SOC) teams.
Understanding unfamiliar scripts can delay investigations, particularly for new team members. Microsoft Security Copilot enhances the library management workflow by analyzing scripts and providing behavioral descriptions and security insights. This AI-driven feature reduces execution errors and boosts analyst confidence.
Additionally, Microsoft’s script analysis capability includes MITRE ATT&CK technique mapping, helping analysts understand the tactics and techniques used in their environment. For junior analysts, Copilot’s natural language explanations bridge skills gaps common in large SOC environments.
The Library Management feature is accessible from the live response page within the Microsoft Defender portal and is available in preview. Security teams can utilize this feature to organize their investigation tools, explore script previews, and leverage Copilot for better script understanding, enabling a more organized and intelligence-ready response toolkit.
