Buying a SIEM won’t fix detection. A SIEM is an operating platform—your outcomes depend on telemetry quality, detection workflow, and the team model that runs it.
Overview
The “best SIEM” is the one that your team can operate: ingest the right logs, build and test detections, investigate quickly, and produce audit-ready evidence.
Define requirements
- What threats matter (ransomware, account takeover, insider, cloud misconfig)?
- What must you detect in under 15–30 minutes?
- What compliance reporting do you need (UU PDP, ISO 27001, sector regulations)?
- What is your coverage scope (endpoints, identity, cloud, network, apps)?
Telemetry & retention
- Priority logs: identity auth, endpoint activity, admin changes, cloud audit logs.
- Retention: choose based on investigations and compliance—then model cost realistically.
- Normalization: consistent fields and parsing impact every downstream query.
Detection workflow
Evaluate how the platform supports the cycle: hypothesis → build → validate → tune → deploy → measure.
- Rule management and versioning
- Testing with sample events and replay
- Alert enrichment and investigation views
- Case management and handoffs
Cost drivers (don’t get surprised)
- Ingest pricing (GB/day), retention tiers, and query costs
- Log sources that explode volume (DNS/proxy/netflow) without filtering
- Engineering time to maintain parsing and detections
- Integration and automation add-ons
