CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Mid-market and enterprise teams drowning in alert fatigue will find real value in Fidelis Security's deep session inspection and AD-aware network detection, which cut false positives by correlating endpoint and network signals that most XDR platforms treat separately. The platform covers all four NIST Detect and Respond functions with particular strength in continuous monitoring and incident analysis through 300+ forensic attributes and automated response capabilities. Skip this if you need a lightweight, cloud-native XDR; Fidelis is built for organizations with the infrastructure to run hybrid deployments and the analyst headcount to operationalize deception strategies like poisoned data and decoys.
