How to choose security monitoring software

  1. Identify the threat surface

    Logs across many sources: SIEM (Splunk, Sumo, Sentinel). Cloud posture (AWS/GCP/Azure config): CSPM (Wiz, Lacework, Prisma). Endpoints (laptops, servers): EDR (CrowdStrike, SentinelOne). Each has different data ingestion and analysis patterns.

  2. Audit cost vs coverage

    Splunk is famously expensive at volume; Sentinel/Sumo are cheaper for similar coverage. Wiz pioneered the agentless CSPM model; legacy agent-based tools (Prisma) feel heavier. Get a real quote for your data volume.

  3. Plan for analyst workflows

    SIEM is only useful if security analysts actually triage alerts. The platform's correlation, deduplication, and alert quality matter more than raw feature count. Test with your real alert volume before committing.

Honorable mentions

Tools that didn't crack the headline list but deserve a look depending on what you optimize for.

  • Microsoft Sentinel logo
    Microsoft SentinelBest SIEM for Microsoft shops

    Microsoft Sentinel integrates natively with Entra ID, Defender, and the Microsoft security stack. For Microsoft customers, it's the rational default at lower cost than Splunk.
