CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams with mature detection programs need Splunk Enterprise Security for alert fatigue reduction, not raw event collection. Risk-Based Alerting cuts false positives by surfacing genuine threats first, while built-in SOAR automation and UEBA handle investigation at scale; the platform covers detection and response workflows with particular strength in incident analysis and mitigation (RS.AN, RS.MI). Skip this if your primary need is asset discovery or you're still building foundational monitoring; Splunk assumes you already have detection signals worth prioritizing.
Teams running hybrid infrastructure who can't justify a $500K annual XDR bill will find Wazuh's free tier genuinely capable for threat detection and log analysis across endpoints and cloud workloads. The platform handles agent deployment at scale without licensing friction, and it covers NIST Detect functions well enough that most mid-market organizations won't feel the gap. Skip Wazuh if your team needs managed SOC services or hands-off threat hunting; this is a build-it-yourself platform that demands internal ops expertise to tune detection rules and manage alert noise.
