EDR uses more complex analysis to detect abnormal user or process behavior or data access, and then tag or possibly block it. More importantly, EDR systems have a wide range of capabilities that can detect and fight attacks and malware infections after occurrence, while antivirus systems are usually invalid if they cannot capture malware when they arrive.
EDR vs. Extended Detection and Response (XDR)
EDR is not the only detection and response security software on the market. Just as EDR focuses on endpoints, there is Network Detection and Response (NDR), which works similarly but focuses on network traffic. Then there is the extended detection and response (XDR), which is bundled with detection and response capabilities, focusing on multiple infrastructure components, including endpoints and networks, as well as email, cloud environments, and others.
When we say “bundle”, we mean: XDR products tend to be a single collection of tools concentrated at different infrastructure layers, and a range of services that take XDR as XDR can be a bit confusing. In fact, many XDR products start with EDR tools that have new layers and capabilities. Intrusion detection and prevention systems (IDS/IPSES) like antivirus are signature-based and are one of the traditional security tools that are swallowed up into NDR and XDR solutions.
