The Cybersecurity SaaS-pocalypse: Open-Source SIEM on Bare Metal

说明与用途

组织通过将日志存储和处理迁移到自有 NVMe 服务器，消除了昂贵的云 SIEM，成本降低 96.7%，并消除了出口税。

问题

Organizations face exploding security telemetry volumes, making traditional SaaS SIEMs financially unsustainable and vulnerable during attacks due to per‑GB pricing and cloud egress costs.

结果

By decoupling compute from storage and moving to bare‑metal NVMe, SOCs reduced annual TCO from ~$180,000 to ~$6,000, a 96.7% savings, while eliminating cloud egress taxes and ensuring real‑time log ingestion.

工作流

• 1. Deploy Wazuh, OpenSearch, and MinIO on dedicated bare‑metal NVMe servers.
• 2. Configure fluent‑bit to tail AI agent logs, drop debug noise, and forward all logs to MinIO.
• 3. Set fluent‑bit to forward only critical events to OpenSearch for real‑time analysis.
• 4. Store long‑term logs in MinIO cold storage, eliminating egress costs.
• 5. Monitor write IOPS to ensure unthrottled performance and maintain data sovereignty.

证据

Commercial SIEM platforms utilize data-volume pricing models averaging roughly $1,800 per GB per day, annually.
