Key Capabilities
Core Components
PowerShell Module The backbone of the tool, this module includes pre-built cmdlets for authentication, live response execution, detection rule management, and advanced threat hunting. It eliminates repetitive scripting, allowing teams to focus on strategic tasks.
Orchestration Platform A serverless automation engine that handles large-scale actions like script deployment and live response across multiple endpoints. No infrastructure management is required, making it ideal for lean security teams.
Threat Intelligence Manager Automates the lifecycle of IOCs (indicators of compromise), including file hashes, domains, and certificates. It also validates and syncs custom detection rules from Azure Blob Storage with built-in version control.
Action Manager Tracks pending security actions and includes an emergency stop feature to halt operations if needed, critical for maintaining control during rapid response scenarios.
Hunt Manager Facilitates proactive threat hunting with scheduled or manual queries, storing results in Azure Blob Storage for analysis.
Incident Manager Provides a unified view of Defender XDR incidents, tracking updates and comments to improve collaboration during investigations.
Available for free on GitHub, MDEAutomator is a game-changer for organizations looking to maximize their MDE investment. By automating routine tasks, security teams can redirect their efforts toward high-priority threats and strategic initiatives.
