A BRIEF HISTORY AND CURRENT TRENDS OF EDR (Endpoint Detection and Response)

The term EDR stands for Endpoint Detection and Response. It was coined by Anton Chuvakin of Gartner in 2013. It refers to tools primarily focused on detecting and investigating suspicious activities and other problems on hosts/endpoints such as PCs used by end-users.

EDR software gathers data from endpoint devices and then analyzes the data to reveal potential cyber threats and issues

Organisations used antivirus systems until early 2012 when this technology transitioned to EDR. This transition was informed by attackers developing evasive techniques for running malicious code on endpoints without detection, commonly known as file – less attacks.

Modern EDR tools overcome these threats by continually collecting, processing and centralizing large amounts of data from client systems. They then allow the integration of various tools and techniques to apply more effective and automated filtering and protection to endpoints and systems.

To cope with the continued development of new threats and attack methods, EDRs have had to adapt in various ways such as extending protection and detection beyond endpoints. This is known as XDR. They extend detection and response across broader systems and networks such as cloud services and IOTs. For smaller organizations that want to explore the benefits of XDR without having the necessary security personnel, can rely on managed EDR (MDR) tools. This is offered by managed security services providers as Software as a service (Saas).

EDRs and their continued evolution have proven vital in the protection of organizations’ resources from the ever-persistent threat of cyberattacks
