What is the primary purpose of Endpoint Detection and Response?

The primary purpose of Endpoint Detection and Response (EDR) is to provide visibility to changes on the endpoint. EDR solutions are designed to continuously monitor endpoint activities and gather data that helps detect potential threats, unauthorized changes, or suspicious behavior. By collecting and analyzing this data, EDR tools can identify security incidents in real-time, allowing for a quicker response to threats.

Having visibility into changes on an endpoint is crucial for security professionals as it enables them to understand the state of the system, detect anomalies, and respond to incidents effectively. EDR solutions not only monitor for known threats but also provide insights into various behaviors on the devices, which can help in identifying new or emerging threats.

The other options relate to beneficial but separate functions. Improving system performance or enhancing user experience are valuable, yet they fall outside the primary security focus of EDR. Monitoring network traffic is essential for overall network security but is more relevant to tools like firewalls and intrusion detection systems, rather than endpoints specifically.
