SIEM vs Detection System of Record (DSoR)
What is the difference?
A SIEM is an execution system: it ingests telemetry, correlates events, and produces alerts. A Detection System of Record is a governance system: it governs how threats map to detections, how controls are validated, and how detection health is measured over time.
SecuMap is a Detection System of Record (DSoR) — a vendor-neutral governance layer that continuously maps threat intelligence to detection coverage, measures detection effectiveness, and governs detection health across the full threat-to-detection operating loop.
These two layers are complementary. SIEM executes detection logic. DSoR governs lifecycle confidence and improvement. Teams that treat them as interchangeable often over-index on alert volume while under-managing coverage quality and validation traceability.
SIEM responsibilities
- Telemetry ingestion and normalization
- Rule execution and event correlation
- Alert routing and search workflows
DSoR responsibilities
- Threat-to-detection mapping governance
- Validation and lifecycle traceability
- Detection health and effectiveness measurement
