Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams that need to catch zero-days and unknown exploits before they spread should deploy GrammaTech ARTCAT for its behavioral runtime monitoring that works without signatures. The tool's reasoning engine automatically generates corrective actions from policy templates, letting you move from detection to mitigation in seconds rather than hours, and NIST CSF 2.0 coverage across Detect, Respond, and Protect reflects that end-to-end capability. Skip this if you're looking for a general-purpose EDR to replace your existing endpoint agent; ARTCAT is purpose-built for runtime anomaly response and works best as a specialized layer on top of your existing detection stack.
Mid-market and enterprise teams managing high-risk web applications should pick Source Defense Platform if third-party JavaScript is your actual attack surface. The platform's real-time sandboxing and AI-driven detection of formjacking and keylogging attacks addresses a gap most ASPMs ignore, and its support for PCI DSS and GDPR compliance violations gives you the audit trail you need. Skip this if your threat model centers on server-side vulnerabilities or you need deep integration with your existing WAF; Source Defense is client-side focused, which is its strength and its limitation.
