Why EDR is not Enough?

Why EDR is not Enough? If we need XDR (Extended Detection and Response)? XDR, or Extended Detection and Response, is the next step in the evolution of Endpoint Detection and Response (EDR): a group of tools or capabilities focusing on the detection of suspicious activities on endpoints. Unlike earlier security solutions, EDR tools were designed to identify anomalous activities and alert security teams to trigger further investigation, rather than simply identifying and quarantining files suspected of malware. However, most EDR solutions aren’t scalable because they’re too resource intensive. Waiting for a response from the cloud or for an analyst to take action isn’t always feasible in the modern threat landscape. Today, networks have far too many endpoints for traditional EDRs to be effective, from mobile phones and IoT devices to cloud-native applications and containers. Sometimes referred to as “Cross-Layered” or “Any Data Source” detection and response, XDR solutions extend beyond these endpoints and make decisions based on data from a variety of sources. They act across an organization’s entire stack, including email, network, identity, and beyond and optimize threat detection, investigation, response, and hunting in real-time. XDR solutions unify security-relevant endpoint detection with telemetry from security and business tools such as network analysis and visibility (NAV), email security, identity and access management, cloud security, and more. How Does XDR Work? XDR solutions deliver detection and response capabilities across all data sources by breaking down traditional security silos.
