An Endpoint Agent is a lightweight software component installed on endpointssuch as laptops, desktops, servers, and mobile devicesto monitor, detect, and respond to security threats in real time. It acts as a frontline defense, collecting telemetry data, enforcing security policies, detecting anomalies, and blocking malicious activity such as malware, ransomware, or unauthorized access. Endpoint agents are key elements in Endpoint Detection and Response (EDR), Extended Detection and Response (XDR), and Zero Trust frameworks. They integrate with central security platforms to provide continuous visibility and control, even when devices are off-network. By securing endpoints, organizations strengthen their overall cybersecurity posture and reduce the risk of breaches from the ground up.
