Endpoint detection and prevention refers to security controls that monitor devices such as computers and servers, along with related systems, for suspicious behavior and attempted compromise. These tools collect activity signals and may block malicious actions, isolate a device, or alert security teams for investigation.
Endpoints are common targets for malware, credential theft, and unauthorized access, so monitoring them helps organizations detect threats that may bypass other defenses. In real attacks, endpoint tools can flag suspicious processes, unusual file changes, or attempts to disable security software. Defenders use their alerts alongside access controls, network monitoring, and incident-response procedures; effectiveness depends on proper configuration, coverage, and timely response.
