EDR / XDR: detection at the endpoint level
EDR (Endpoint Detection and Response) continuously monitors the behavior of a workstation or server to detect malicious activity, whereas a traditional antivirus is limited to comparing files against known signatures. XDR extends this approach to multiple sources (endpoints, network, cloud).
Definition
A traditional antivirus blocks threats that are already catalogued. An EDR observes process behavior in real time — creation of suspicious files, abnormal network connections, privilege escalation — and can detect an attack even when the malicious file has never been seen before.
XDR (Extended Detection and Response) broadens this monitoring beyond the endpoint by correlating signals between endpoints, network and cloud environments, to reconstruct an attack chain that may span several systems.
Key points
Behavioral monitoring
EDR observes what a process does, not just what it is, making it possible to detect previously unseen threats.
Tool-supported response
Automatic isolation of a compromised endpoint, blocking a process: EDR is not limited to alerting.
XDR: a broader view
By cross-referencing multiple data sources, XDR helps reconstruct an attack that progresses from one system to another.
How BCIT can support you
Deploying an EDR is often one of the recommendations that emerges from our security audits, particularly when facing the risk of ransomware.
Frequently asked questions ❓
Does an EDR replace an antivirus?
It complements it and goes further: EDR continuously observes process behavior, making it possible to detect previously unseen threats that a traditional antivirus would miss.
Is XDR useful for a small organization?
Its value increases with the diversity of environments to monitor (endpoints, cloud, network); a small organization can first focus on a well-deployed EDR.
