What it means
EDR can reveal process chains, command execution, persistence, credential access, file changes, and network connections that are difficult to see from network logs alone.
Why it matters
Because many attacks execute on endpoints, detailed host telemetry helps analysts distinguish a blocked event from an active compromise.
Practical focus
- Deploy coverage to critical and remote endpoints
- Protect the agent and management plane
- Tune detections using environment context
- Define approval and safety rules for response actions
Common mistakes
- Assuming installation equals effective monitoring
- Ignoring gaps on servers and privileged workstations
- Taking destructive response actions without preserving evidence
