How EDR Collects Endpoint Telemetry and Adds Context Beyond Antivirus

Summary

The article explains how EDR collects endpoint telemetry over time to add context beyond antivirus alerts, and outlines the data and response capabilities Huntress says its managed EDR provides.

Key points

• The article contrasts traditional signature-based antivirus and machine-learning-based NGAV with EDR’s ongoing collection of endpoint activity.
• EDR telemetry can provide context before, during and after an antivirus alert, helping teams investigate an attack’s timeline and root cause.
• Examples of telemetry include process commands and lineage, user logons, file and registry changes, network activity, autoruns and host surveys.
• The article notes that telemetry kept only on an endpoint may be exposed to ransomware encryption, adversary modification or deletion, or device failure.
• Huntress says its managed EDR aggregates telemetry in its cloud and combines analytics with human detection engineering, threat hunting and analyst review.
• Huntress also describes ransomware canaries, investigative data collection and remediation actions as features of its managed service.
