Modernizing SecOps: A Guide to Moving Beyond Legacy SIEMs

A comprehensive playbook for the full Cloud SIEM detection lifecycle.

Legacy SIEMs were built for a different era. Security operations teams spend more time managing the tool than investigating threats - sifting through noisy alerts, dealing with unpredictable costs and working around workflows that weren’t designed for dynamic, modern cloud environments.

In this guide, we walk through a proven five-phase detection lifecycle, covering everything from data normalization and rule development, to AI-assisted investigation and automated response. You’ll learn how to:

• Build and validate detection rules against historical data before deploying to production
• Accelerate onboarding with 1,000+ pre-built integrations, detection content, and workflows
• Reduce alert fatigue using risk-based entity context and AI-driven prioritization
• Automate response with SOAR workflows for identity, host, and ticketing systems
• Scale log retention cost-effectively without compromising query performance
