Endpoint Detection and Response (EDR), also referred to as endpoint detection and threat response (EDTR), is an endpoint security solution that continuously monitors end-user devices to detect and respond to cyber threats like ransomware and malware.

EDR security solutions record the activities and events taking place on endpoints and all workloads, providing security teams with the visibility they need to uncover incidents that would otherwise remain invisible. An EDR solution needs to provide continuous and comprehensive visibility into what is happening on endpoints in real time.
