The great SIEM paradox: does more data equal better security?

This whitepaper explains that collecting everything into a SIEM leads to noise, high storage costs, and analyst fatigue; it recommends prioritizing high-fidelity telemetry (cloud control plane, identity, EDR, Kubernetes) for SIEM, storing low-fidelity/high-volume data in a data lake, and using Expel MDR for alert enrichment, triage, and 24×7 monitoring to optimize costs and detection outcomes.
