Why Query Optimization Matters

Inefficient SIEM queries are one of the biggest hidden costs in security operations. A single poorly written detection rule running every 5 minutes can consume more compute than an entire team's ad-hoc investigations combined.

  • Cost: Cloud SIEM billing scales with data scanned. Wildcard-heavy queries can scan 10-100x more data than necessary.
  • Speed: Slow queries delay alerts, widening the gap between compromise and detection.
  • Reliability: Queries that time out produce gaps in coverage, creating blind spots adversaries can exploit.
  • Capacity: Optimized queries free up ingestion and compute budget for broader coverage.
