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.
