EDR vs Traditional Antivirus: What Actually Changed

Traditional antivirus relies heavily on signatures — a database of known malicious file hashes. It's fast and lightweight, but blind to anything it hasn't seen before, including most modern targeted attacks.

Endpoint Detection & Response (EDR) instead monitors process behavior continuously: what's spawning what, what's touching sensitive files, what's trying to escalate privileges. This catches fileless malware and 'living off the land' techniques that never touch disk in a way antivirus would flag.

EDR also gives you the investigation trail antivirus never could — a timeline of exactly what happened on an endpoint before, during and after an alert, which is critical for both response and post-incident learning.

For most organizations today, EDR isn't a replacement decision anymore — it's a baseline expectation, especially for anything handling sensitive data.
