AhnLab XDR vs GrammaTech ARTCAT: Side-by-Side Comparison (2026)

GrammaTech ARTCAT

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.
