Microsoft Defender XDR is an industry-leading extended detection and response (XDR) platform that provides unified investigation and response capabilities across various assets, including endpoints, IoT devices, hybrid identities, email, collaboration tools, and cloud applications. It offers centralized visibility, powerful analytics, and automatic cyberattack disruption to help organizations detect and respond to threats more effectively. By integrating multiple security services, such as Microsoft Defender for Endpoint, Microsoft Defender for Office 365, Microsoft Defender for Identity, and Microsoft Defender for Cloud Apps, it enables security teams to correlate signals across these services, providing a comprehensive view of threats and facilitating coordinated responses. This integration allows for automatic actions to prevent or stop attacks and self-heal affected assets, enhancing overall security posture.
