TL;DR: MTTR stays high long enough to widen the exposure window, and Todyl says that gives attackers time to move laterally, exfiltrate data, and raise remediation cost. MXDR operations need faster containment workflows because delayed response turns detection into a separate event.
Editorial analysis by NHI Mgmt Group, based on content published by Todyl: “How MXDR Reduces Mean Time to Respond (MTTR) for MSPs”.
By the numbers:
- The global average detection-and-containment lifecycle sits at 247 days, according to IBM's 2025 Cost of a Data Breach Report.
- Attackers exfiltrate data in under five hours in 25 percent of incidents.
Key questions
Q: Why do identity events matter in cloud incident response?
A: Identity events explain how a change became possible and which session or role made it happen.
Q: How can MSPs tell whether automation is actually improving response?
A: Look for shorter containment times, lower dwell time, and fewer manual handoffs in high-confidence incidents.
Q: What breaks when security teams cannot reduce MTTR consistently?
A: The main failure is that detection and containment become separate events, which gives attackers time to move laterally, collect data, or trigger destructive actions.
Practitioner guidance
- Define MTTR by incident class Track MTTR separately for ransomware, credential compromise, cloud misconfiguration, and suspicious identity activity so response bottlenecks are visible instead of averaged away.
- Pre-authorise containment for high-confidence alerts Allow endpoint isolation, process termination, and credential flagging to execute without a human approval cycle when the alert meets a defined confidence threshold.
- Add identity signals to response playbooks Include authentication anomalies, privilege changes, and service-account activity in the containment workflow so responders can shut down the access path, not only the host.
Bottom line: MTTR is the clearest indicator of whether security operations can stop an incident before it expands into lateral movement or data loss.

MTTR is a control variable, not a reporting metric. If a security team cannot shorten the time between detection and containment, it has not yet turned visibility into control. The article is right to treat MTTR as the practical test of whether operations can interrupt an attack before it spreads. For identity-heavy environments, that means the response layer must be able to act on hosts, sessions, and credentials, not just log the incident.
A question worth separating out:
Q: Should teams prioritise MTTR over more detection tools?
A: Yes, when detection already exists but containment still lags. More tooling does not help if the team cannot act quickly enough to stop progression. Organisations should prioritise response workflows, delegated authority, and automation first, then add detection depth where it closes a genuine visibility gap.
