Endpoint Detection and Response (EDR) functions by continually monitoring endpoint activities, evaluating events, generating notifications, and providing automated or guided remediation to reduce the impact of cyber attacks. EDR is adept at collecting and analyzing data to identify potential attacks, thereby increasing visibility into systems and alerting when something appears abnormal.

EDR tools offer a thorough analysis of a wide range of events, covering everything from:

  • standard laptops and desktop PCs
  • mobile devices
  • servers
  • IoT
  • cloud workloads

This helps identify any potential suspicious activity. These tools generate alerts to aid security analysts in uncovering, investigating, and remediating any issues. EDR tools gather telemetry data on any dubious activity. This data can be enhanced even more with additional contextual information gained from connected events.
