Extended Detection and Response (XDR) is a security solution that provides comprehensive visibility, threat detection, analysis, and highly automated response across all your cloud, hybrid, and on-premises data center resources. XDR tools create a unified security analysis environment across all the different security tools an organization has deployed. Open XDR solutions also support an open standard by being able to accommodate and use security telemetry from disparate vendors, unifying the signals and streamlining response operations. The benefits of modern XDR solutions fall into three major categories, including AI-driven correlation at scale, improving operational
efficiency, and addressing skills gaps.

Threat actors today have become extremely sophisticated and are operating as for-profit businesses. They are continuously testing against the most widely deployed security defense tools to bypass existing security solutions in place. This results in more sophisticated and targeted attacks, multi-stage attacks, ransomware, polymorphic malware, social engineering, phishing, and file-less malware reaching unsuspecting users.

In the face of these threats, XDR platforms are replacing Security Information and Event Management (SIEM) correlation by bringing modern AI-driven threat detection, big-data repositories, and streaming analytics to the cybersecurity arena. The amount of data generated by IT environments has grown by orders of magnitude, and the compute and analytics power required to effectively analyze this data has increased at the same rate. XDR analysis solutions can pull together and make sense of EDR, Network Traffic Analysis(NTA), User & Entity Behavior Analytics (UEBA), and several other sources of data deployed for security alerting across the enterprise today.
