TL;DR: Financial services MDR models increasingly miss the very alerts that matter, with Intezer reporting that providers investigate only about 40% of received signals while nearly 1% of confirmed incidents start in low-severity or informational alerts. Coverage, evidence retention, and accountability now matter as much as response speed in regulated environments.
NHIMG editorial — based on content published by Intezer: Financial services need to rethink the MDR model
By the numbers:
- Intezer’s research across 25 million alerts found that nearly 1% of confirmed incidents originated in low-severity or informational alerts.
Questions worth separating out
Q: What breaks when MDR services never fully investigate alerts?
A: When alerts are filtered, auto-closed, or only partially reviewed, the organisation loses timely visibility into real identity and access risks.
Q: Why do identity and cloud signals matter in MDR coverage?
A: Because many attacks begin with credential theft, account takeover, MFA abuse, or cloud misconfiguration rather than endpoint malware.
Q: How do you know if MDR coverage is actually working?
A: Look for evidence that the provider can prove full alert handling by severity tier and telemetry source, not just an SLA on response time.
Practitioner guidance
- Measure actual investigation coverage Break out the percentage of alerts investigated by severity tier and by telemetry source, then compare it with the systems your institution is formally accountable for.
- Extend the control boundary beyond endpoint data Verify whether identity, cloud, email, and network telemetry are fully covered or only lightly batched, especially where credential theft and account takeover are realistic entry paths.
- Demand internal ownership of evidence and detections Require exportable case histories, retained investigative evidence, and SIEM rule ownership so the institution can answer examiner questions without relying on the provider.

MDR is becoming a governance issue, not just a detection service. Financial institutions cannot delegate accountability away from themselves even when they outsource triage. When a provider investigates only part of the queue, the institution still owns the evidence gap, the regulatory response, and the board-facing explanation. That makes MDR renewal a control-design decision, not a procurement refresh.
A question worth separating out:
Q: Should financial services keep MDR or move to an owned AI SOC model?
A: The decision depends on whether the provider can cover the institution’s real attack surface and preserve the evidence the institution must answer for. If the service only partially investigates alerts, then owned investigation and automation become more attractive because they reduce dependence without sacrificing auditability.
