Where does Open-Source SIEM (self-hosted) fit in a CISO program?
Security Information and Event Management (SIEM) platforms aggregate logs from across the estate, run correlation rules, and surface alerts to the SOC. SIEM is the analyst's lens onto everything else: detection engineering quality and the team's ability to tune rules drive most of the value, not the platform itself. Real-world SIEM is ingest-priced (cost scales with log volume in GB/day, not headcount), which is why CISO Game's SIEM tiers are flat-fee. Without a Detection Engineer to tune it, even an enterprise SIEM ships at 30% effectiveness in this game — the same gap that real-world deployments hit when staffing falls behind tooling.
