Extended detection and response, better known as XDR, is a security technology that combines multiple point solutions, including but not limited to endpoint protection and endpoint security tools, into a unified incident detection and response platform. First described in 2018 by Palo Alto Networks' CTO Nir Zuk, XDR collects, correlates, and contextualises alerts from different solutions across endpoints, servers, networks, applications, and cloud workloads.

How many times can we say, “It’s been a busy week for the security industry,” before it becomes cliche? We recently discussed changes in the SIEM market, with mergers and acquisitions disrupting the traditional SIEM vendor landscape and XDR vendors introducing new SIEM solutions. This week, we continue to see a range of mixed messages from the market around the future of XDR and SIEM.
