CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams already invested in Microsoft 365 should use Defender XDR because automatic attack disruption stops compromises mid-chain without waiting for human intervention, cutting response time from hours to minutes. Its NIST RS.MI (Incident Mitigation) strength,auto-healing of affected assets and real-time containment,means threats don't expand while your analysts are still triaging. Skip this if your environment is non-Microsoft heavy; XDR's correlation engine is built around Microsoft signals, and bolting on third-party tools dilutes that advantage.
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.
