Endpoint Detection and Response (EDR) is a modern cybersecurity technology that continuously monitors endpoint devices, detects suspicious or malicious activity, and provides automated and analyst‑driven responses to stop cyber threats like ransomware, malware, zero‑day attacks, and fileless intrusions.

EDR is a security technology that continuously monitors endpoints for evidence of threats and takes automatic actions to mitigate them.

EDR goes far beyond traditional antivirus tools—it provides behavioral detection, threat hunting, forensics, and rapid incident response.

‍

How it works

EDR operates through a combination of endpoint monitoring, behavioral analytics, and automated containment:

1. Continuous Monitoring & Data Collection

Lightweight agents record activity on endpoints—files, processes, network connections, and user behavior.

2. Behavioral Analysis & Threat Detection

Machine learning and analytics detect anomalies, unknown threats, and signs of compromise—not just signature‑based malware.

3. Automated Response & Containment

EDR can isolate infected devices, kill malicious processes, block connections, or roll back system changes (including ransomware encryption).

4. Investigation & Forensics

EDR tools store and analyze endpoint telemetry so analysts can determine:

• how the attack happened
• what systems were affected
• what remediation is needed

Why it matters

Better than Antivirus Alone

Traditional antivirus looks for known malware.
EDR detects unknown, fileless, and behavior‑based attacks.

Stops Ransomware

EDR can detect encryption behavior and roll back malicious changes to the state before files were encrypted.

Full Endpoint Visibility

EDR gives security teams a detailed timeline of events leading up to an attack.

Fast Incident Response

Most modern breaches begin at the endpoint, EDR empowers teams to stop threats early.
