CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams with network visibility gaps who lack budget for commercial NDR will find Joy's free flow analysis genuinely useful for baseline threat hunting and anomaly detection. The 1,356 GitHub stars and active open-source community signal real production use, particularly among smaller shops and resource-constrained security groups. Skip this if you need managed threat hunting, automated response playbooks, or vendor support; Joy is a capture-and-analyze tool that demands internal expertise to operationalize effectively.
Mid-market and enterprise teams managing hybrid infrastructure need IronNet IronDefense for east-west traffic visibility that most NDR tools skip in favor of perimeter-only monitoring. The 30, 60, and 90-day PCAP retention windows combined with behavioral ML analysis let you hunt backward through months of traffic without relying on external logs, which is where IronDefense's forensic edge actually sits. Skip this if your organization treats NDR as a checkbox for compliance rather than an active hunting platform; the tool prioritizes detection and investigation over automated response, so it rewards teams with dedicated SOC capacity.
