SOC Tooling Overview

This page will survey the major tool categories in a Security Operations Center — SIEM, EDR, IDS/IPS, and SOAR — with honest comparisons of the leading options in each category on features, cost, operational overhead, and organizational fit. It will help a team choosing their first SOC stack or evaluating whether to replace an existing tool make an informed decision without vendor-driven noise.

Topics to cover

SIEM platforms — Splunk (enterprise, expensive, powerful), Elastic SIEM (open core, flexible, operationally demanding), Wazuh (fully open source, SIEM + HIDS), Microsoft Sentinel (cloud-native, Azure-integrated): strengths, real costs, and fit by org size
EDR solutions — CrowdStrike Falcon, SentinelOne, Elastic EDR (free tier), Microsoft Defender for Endpoint: detection quality, response capabilities, platform compatibility, licensing models
IDS/IPS — Snort (rules-based, widely deployed), Suricata (multi-threaded, Suricata rules + Snort rules), Zeek (network metadata, not alerts): how they differ and when to use each
SOAR platforms — XSOAR (Palo Alto), Swimlane, open-source options (Shuffle, TheHive + Cortex): playbook automation, case management, alert triage
Threat intel integration — MISP, OpenCTI, commercial feeds (Recorded Future, Mandiant): how to operationalize threat intel in your SIEM and EDR
Open-source vs commercial trade-offs — total cost of ownership, operational staffing requirements, detection quality, vendor support, compliance reporting
Sizing and cost estimation — rule of thumb ratios (EPS, GB/day, analyst headcount), common underestimation pitfalls, how to build a realistic budget ask
