EDR

Also known as: Endpoint Detection and Response

Endpoint Detection and Response — a security platform that monitors endpoint activity, detects threats, and supports incident response.

Endpoint Detection and Response (EDR) is a category of security software that monitors endpoint activity (workstations, servers, laptops) in real time, detects suspicious behavior, and enables rapid response to incidents. Modern EDR platforms include CrowdStrike Falcon, Microsoft Defender for Endpoint, SentinelOne, Trellix, and Sophos Intercept X.

For CMMC purposes, EDR is the most common way to satisfy SI.L2-3.14.2 (malicious code protection), SI.L2-3.14.3 (security alert monitoring), SI.L2-3.14.4 (update mechanisms), and SI.L2-3.14.5 (periodic scans) simultaneously.

A C3PAO will verify EDR coverage on every in-scope endpoint (no gaps), the alert response workflow, and the chain of custody for any flagged events.
