In cybersecurity, an endpoint is any device that connects to a network, such as a computer, server, smartphone, tablet, virtual machine, or IoT device. The word means the end point of a network connection. Endpoint security or EDR (Endpoint Detection and Response) protects these devices from malware, intrusions, and ransomware by monitoring activity and responding to threats directly on the device.
EDR (Endpoint Detection and Response) is a cybersecurity solution that monitors endpoint activity to detect and respond to threats. It plays a key role in MDR (Managed Detection and Response), which combines EDR tools with expert analysis and real-time response.
Domain names are relevant in this context because many threats involve malicious domains used for phishing, malware delivery, or command-and-control. MDR services analyze domain activity to detect such threats and block them.
Leading EDR providers include CrowdStrike, Microsoft, SentinelOne, and Sophos, whose platforms are often used as the core detection layer in MDR offerings.
