Endpoint detection and response, or EDR, is a security capability that monitors endpoint activity and helps teams investigate and respond to threats. EDR matters because many attacks begin or become visible on user and server devices before defenders understand the full scope.
What is Endpoint Detection and Response (EDR)?
EDR tools collect endpoint telemetry, detect suspicious behavior, preserve evidence, and support containment or remediation actions. They are commonly used to identify malware, persistence, privilege escalation, credential abuse, and lateral movement on devices.
Unlike traditional antivirus alone, EDR focuses not just on blocking known threats but on visibility, investigation, and response for active attacks.
What EDR Helps Detect
EDR helps detect suspicious processes, malicious scripts, ransomware behavior, credential theft techniques, unusual parent-child process chains, persistence mechanisms, and attacker use of legitimate tools.
EDR vs. Antivirus
Antivirus mainly focuses on preventing or removing known malicious software. EDR goes further by capturing endpoint behavior and helping security teams investigate and respond to active or evolving threats.
Frequently Asked Questions
Does EDR replace all endpoint security controls?
No. EDR is powerful, but it works best alongside patching, hardening, MFA, encryption, least privilege, and broader endpoint security operations.
Why do attackers care about endpoints so much?
Endpoints are where users click, credentials are handled, scripts run, and many attacks first gain traction before spreading deeper into the environment.
