You’re Investing in EDR, But Are You Actually Protected?

Keeping every EDR agent properly installed, tuned, and effective across hundreds or thousands of endpoints is a constant challenge. Attackers now use AI to evade, disable, or blind EDR tools, and most organizations have no proof their defenses are actually working.

Autonomous, Agentless, Evidence-Based Validation

NodeZero safely emulates real-world attacks in production to test whether your EDR detects, alerts, and blocks what matters, then provides forensic proof mapped to MITRE ATT&CK.

Which attacks were detected, blocked, or missed

Coverage gaps across MITRE ATT&CK techniques

Timestamps and forensic proof aligned with your SIEM/EDR logs

One-click verify after policy changes — no agents required
