Endpoint Detection and Response (EDR) technologies provide comprehensive visibility and real-time threat prevention directly on endpoint devices. EDR continuously monitors process activities, file executions, and system calls to detect malware, suspicious behaviors, and zero-day threats at the source. Palo Alto Networks’ Cortex XDR platform exemplifies this by correlating endpoint telemetry with network and cloud data to provide a holistic defense against attacks. Operating locally on endpoints allows EDR to prevent lateral movement and respond to threats quickly, filling security gaps that network-centric tools alone cannot address. This endpoint-level insight is critical to identifying sophisticated threats that initiate or manifest on user devices.
