XDR is new to the marketplace, and there remains confusion about what it is - and is not. Alex Kirk of Corelight likes to dispel the myth that it's about endpoint security. "You've got to have the N," he says - network technology. In this interview, he dispels myths and expounds on possibilities.

In this video interview with Information Security Media Group, Kirk discusses:

• How XDR distinguishes itself from other solutions
• The critical importance of network technology
• XDR's relationship with the SIEM

Kirk is a veteran open-source security evangelist with a deep engineering background. In 10 years with Sourcefire Research (VRT), he wrote the team’s first malware sandbox and established its global customer outreach and intelligence sharing program. He has spoken at conferences across the globe on topics ranging from "Malware Mythbusting" to "Using Bro/Zeek Data for IR and Threat Hunting" and was a contributing author for "Practical Intrusion Analysis," an oft-used textbook for university courses on IDS.
