Extended Detection and Response (XDR) is a unified security incident platform that leverages AI and automation to protect organizations against advanced cyberattacks across various domains. Unlike targeted systems like Endpoint Detection and Response (EDR), XDR expands its coverage to safeguard against more sophisticated threats. Here are some key capabilities of XDR:
Incident-based investigation: XDR collects low-level alerts and correlates them into incidents, providing security analysts with a comprehensive view of potential cyberattacks. This streamlines productivity and enables faster responses.
Automatic disruption of advanced cyberattacks: By using high-fidelity security signals and built-in automation, XDR detects ongoing cyberattacks and initiates effective incident response actions. These actions include isolating compromised devices and user accounts, effectively disrupting attackers.
Cyberattack chain visibility: XDR ingests alerts from a wider range of sources, allowing analysts to view the complete cyberattack chain of sophisticated attacks that might otherwise go undetected by point security solutions. Enhanced visibility reduces investigation time and increases the likelihood of successful remediation.
Auto-healing of affected assets: XDR employs built-in automation to return compromised assets (such as those affected by ransomware, phishing, or business email campaigns) to a safe state1.
In summary, XDR provides a holistic approach to threat protection and response, integrating detection, investigation, and response capabilities across endpoints, hybrid identities, cloud applications, email, and data stores.
