XDR, SIEM, or Beyond?

Security operations options continue to multiply, and terminology is cluttered. Will XDR replace SIEM? Is SIEM truly dead? And what does AI SOC actually solve? This document organizes these three frameworks by technical layer, demonstrating that whether your starting point is EDR, XDR, or if you do not yet have dedicated monitoring tools, as your business grows, the destination converges on a configuration where AI SOC handles response built on a SIEM foundation.

Key Findings
01 — 60% of alerts go uninvestigated. SOCs receive thousands of alerts daily, with 62% remaining unaddressed. 73% of organizations identify false positives as their biggest challenge.
02 — XDR and SIEM are not mutually exclusive. XDR prioritizes deep integration and operational agility over broad coverage and long-term retention. Aggregating diverse logs and compliance auditing remain the job of SIEM.
03 — The value of AI and automation is proven. Organizations employing extensive AI and automation shortened the time to identify and contain breaches by 80 days, saving approximately $1.9 million per incident.
04 — Adoption stands at just 1% to 5%. AI SOC agents are at the peak of inflated expectations, with implementation still in its infancy. Designing the scope of automation and final human decision-making beforehand is essential to unlocking its value.
