Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams at mid-market and enterprise organizations that need detection and response without the SaaS licensing overhead should seriously consider Wazuh Extended Detection and Response. Its open source foundation means you control deployment costs across hybrid infrastructure, and the platform covers the full detection-to-mitigation chain: continuous monitoring catches anomalies, behavioral analysis flags compromises, and the active response module actually stops threats instead of just alerting on them. Skip this if your team is understaffed and wants a fully managed service; Wazuh requires hands-on tuning and threat intelligence curation to deliver its value.
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.
