EDR Healthcheck

EDR Healthcheck is a security validation tool from Horizon3.ai that tests the effectiveness of endpoint detection and response (EDR) solutions. The product is part of the NodeZero platform and performs autonomous penetration testing to validate whether EDR systems can detect and respond to real-world attack techniques. The tool executes actual attack scenarios against endpoints to measure detection capabilities, providing organizations with empirical data on their EDR effectiveness. It operates as part of a broader autonomous pentesting platform that can assess internal networks, external attack surfaces, cloud environments, Kubernetes deployments, and Active Directory configurations. EDR Healthcheck enables security teams to identify gaps in endpoint security controls by simulating adversary techniques and measuring detection rates. The testing approach provides actionable insights into which attack methods evade detection, allowing teams to tune their EDR configurations and improve overall endpoint security posture. The product supports continuous security validation through automated testing cycles, enabling organizations to verify EDR effectiveness after configuration changes, updates, or new deployments. Results are delivered through the NodeZero platform interface, which provides detailed reporting on detection successes and failures across tested endpoints.
