TL;DR
CDR focuses on detecting and responding to threats inside cloud environments (IaaS/PaaS/SaaS, containers, serverless) using cloud‑native telemetry. XDR unifies detections and response across domains (endpoints, network, identity, email and cloud). Use CDR for deep cloud visibility; use XDR to correlate signals enterprise‑wide.
As organizations rapidly migrate to cloud infrastructures, the security landscape has become increasingly complex. With 99% of cloud security failures attributed to customer misconfigurations and a projected 300% increase in cloud-targeted cyber threats by 2025, choosing the right detection and response solution has never been more critical. Security teams face a pivotal decision: should they invest in Cloud Detection and Response (CDR) or Extended Detection and Response (XDR)?
Both technologies promise unified threat visibility and faster response times, but they approach the problem from fundamentally different angles. While XDR casts a wide net across your entire digital infrastructure, CDR dives deep into the unique complexities of cloud-native environments. The question isn’t which one is better—it’s which one (or both) fits your organization’s cloud security architecture.
What Is Cloud Detection and Response (CDR)?
Cloud Detection and Response (CDR) is a cloud-native security solution specifically designed to identify, analyze, and respond to security threats within cloud environments.
