Endpoint Detection and Response (EDR)
EDR (Endpoint Detection and Response) is a security solution that continuously monitors endpoint devices — laptops, desktops, servers — to detect suspicious activity, investigate threats, and enable rapid incident response.
Core Capabilities
- Continuous Monitoring: Real-time collection of endpoint telemetry (process execution, file modifications, network connections, registry changes)
- Threat Detection: Behavioral analysis and machine learning to identify malicious activity
- Incident Investigation: Detailed forensic data for understanding attack scope and timeline
- Automated Response: Ability to isolate compromised endpoints, kill malicious processes, and quarantine files
- Threat Hunting: Query capabilities for proactive searching across endpoints
How EDR Works
EDR agents installed on endpoints capture behavioral telemetry and send it to a central platform for analysis. Detection engines apply rules, machine learning models, and behavioral analysis to identify threats. Security analysts investigate alerts, and automated playbooks can take immediate containment actions.
EDR vs. Traditional Antivirus
| Feature | Traditional AV | EDR |
|---|---|---|
| Detection Method | Signature-based | Behavioral + ML |
| Visibility | Limited | Full endpoint telemetry |
| Response | Block/quarantine | Isolate, investigate, remediate |
| Threat Hunting | Not supported | Core capability |
| Forensics | Minimal | Rich historical data |
Key Considerations
- Agent performance impact on endpoints
- Cloud vs. on-premises deployment models
- Integration with SIEM and SOAR platforms
- Coverage across Windows, macOS, and Linux
- Detection validation against real attack techniques
