Session overview

Mean time to respond is shaped by the full incident path: signal quality, triage, investigation, decision-making, action, and review. Optimising only one step can move the delay elsewhere rather than improving the operating model.

This session examines the practical levers that reduce response time: Defender XDR correlation, response automation, Security Copilot assistance, and the measurement discipline that keeps improvements honest. The emphasis is on where technology removes friction and where human judgement and governance remain essential.

What attendees will take away

  • A practical model for identifying the stages that contribute to MTTR
  • Where correlation, automation, and Copilot assistance can reduce response friction
  • How to measure improvement without relying on speed alone

Audience

  • SOC and security operations leaders
  • Defender XDR architects and practitioners
  • Teams introducing automation or Security Copilot into incident response
