Endpoint Detection and Response (EDR)

Traditional antivirus software mainly matches files against a list of known-bad signatures. EDR goes further by watching behaviour in real time — what a process is doing, what it is connecting to, what it is trying to change — so it can catch attacks that do not match any known signature, including many ransomware variants. Modern EDR platforms typically combine this monitoring with automated response, such as isolating a compromised device from the network the moment suspicious activity is detected, and feed alerts into a security team or managed detection service for investigation.

EDR has become a practical necessity rather than a luxury for organisations of any size, because ransomware and other malware increasingly evade signature-based defences. For smaller Caribbean businesses without an in-house security team, EDR is usually deployed with a managed detection and response (MDR) service, so alerts are triaged and acted on around the clock rather than sitting unread in a console.
