EDR Security Explained: What are The Fundamentals of Endpoint Detection and Response?

Endpoint Detection and Response (EDR), also referred to as endpoint detection and threat response (EDTR), is an endpoint security solution that constantly monitors end-user devices to detect and respond to cyber threats like ransomware, malware and any other potential threats. This term was coined by Anton Chuvakin at Gartner to describe security systems that detect and investigate malicious activities on both hosts and endpoints. These systems heavily rely on automation, enabling security teams to identify and respond to threats immediately.

The key functions of the EDR security systems are to gather information about the activities happening at endpoints that may potentially indicate a security risk and prevent security breaches. It analyzes this data to identify potential threats and their patterns. Then it automatically responds to the identified threats in order to remove them and notify security personnel. It uses analysis tools to investigate security risks and seek for any suspicious behavior and then to isolate compromised endpoints in case of emergency. We can definitely name EDR solutions as the modern threat hunters in the digital world, looking for and preventing any suspicious system behavior.

EDR is designed with the purpose of protecting the users, devices, and IT resources of an organization against cyber threats that manage to bypass antivirus software and other security tools. EDR has the capability to identify risks such as ransomware and malware and to isolate them and prevent further damage.
