Endpoint Detection and Response (EDR) is a security technology focused on continuously monitoring and responding to threats on endpoints—such as computers, servers, and mobile devices—within a network. EDR systems collect and analyze vast amounts of data from endpoint activities, identifying signs of malicious behavior or potential cyber attacks. By leveraging machine learning and behavioral analysis, EDR detects threats that traditional antivirus may miss, such as zero-day attacks and advanced persistent threats. It provides in-depth insights and alerts, allowing security teams to investigate and respond quickly to incidents. Additionally, EDR tools often include automated responses, like isolating compromised devices, to contain threats and minimize damage, helping organizations improve their overall security posture by enabling proactive threat hunting and fast remediation.
