## 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

## What’s Included in Your Healthcheck

- Agentless setup in under 1 hour
- Full report showing real attack scenario outcomes
- Evidence for tuning and verification
- Expert review session with our team
- Continuous validation options after your checkup

## Understand the Full Impact of EDR Healthcheck

This solution brief shows how NodeZero evaluates your EDR stack the way an attacker would—highlighting missed detections, ineffective rules, and real opportunities for improvement. Use it to align stakeholders and plan targeted remediation with confidence.
