EDR

A cybersecurity technology designed to monitor, detect, investigate, and respond to threats that target endpoints—such as laptops, desktops, servers, and mobile devices. Endpoints are often the first line of attack because they represent the devices users interact with daily, making them vulnerable to phishing, malware, ransomware, and insider threats.

EDR platforms continuously collect data from endpoints, including process activity, file changes, network connections, and system behavior. This telemetry is then analyzed to detect anomalies or malicious patterns that traditional antivirus solutions might miss. Unlike signature-based security tools, which rely on known threat databases, EDR uses behavioral analysis, heuristics, and increasingly machine learning to identify novel or advanced threats.

One of the defining features of EDR is its ability to facilitate incident response. Security teams can use EDR tools to isolate compromised devices from the network, stop malicious processes, and roll back harmful changes, all in near real-time. This helps contain attacks quickly and prevents lateral movement within the organization’s infrastructure.

In addition to detection and response, EDR solutions often integrate with broader security operations, feeding data into SIEM (Security Information and Event Management) systems or being extended into XDR (Extended Detection and Response) platforms. Together, they provide a holistic view of threats across endpoints, networks, and cloud systems.

For organizations of all sizes, EDR has become essential as part of a layered defense strategy. With the rise of remote work, cloud adoption, and sophisticated cyberattacks, securing endpoints is no longer optional—it is one of the most critical components of protecting digital assets and maintaining business continuity.
