Who this page is for
IT and security leaders, SOC teams, procurement and anyone evaluating, rolling out or improving EDR.
What is EDR?
Endpoint Detection and Response collects detailed endpoint telemetry, detects suspicious behaviour and enables responses such as quarantine or network isolation, usually centrally.
Difference from classic antivirus
Antivirus mostly detects known patterns. EDR analyses behaviour, captures context across processes, network and files, and enables traceable investigation. Modern solutions combine both.
Typical capabilities
Telemetry: processes, command lines, network, files, scripts.
Behaviour analytics: chains of activity, not just signatures.
Isolation: cut affected devices from the network.
Response: kill processes, collect files, automated workflows.
Forensics: retrospective view of past activity.
Limits of EDR
EDR only protects where it is installed and allowed to collect telemetry. Servers without agents, third-party systems or unmanaged devices fall outside its view. Without analysis by a SOC or MDR, much of the value is lost.
Value for SOC and incident response
For a SOC EDR is often the most important log source because endpoints are the primary target. During an incident EDR provides telemetry for incident response and enables fast containment.
Checklist
- EDR rolled out to all relevant endpoints
- Server workloads included
- Telemetry forwarded to SIEM or detection platform
- Clear ownership of analysis
- Playbooks for typical EDR alerts
- Update and exception management defined
Frequently asked questions
+Do I still need classic antivirus?
Modern EDR usually includes classic protection. Stacking two products often causes more problems than benefits.
+Does EDR replace a SOC?
No. Without human analysis and context, value stays on the table. EDR provides the data, the SOC or MDR interprets it.
+How does EDR relate to XDR?
[XDR](/en/xdr) extends the endpoint view to further sources such as identity, mail and cloud.
