'EDR' refers to Endpoint Detection and Response, a critical component in modern end-user security. EDR solutions continuously monitor and respond to threats on endpoints such as laptops and servers. They detect suspicious activity, provide analytics, and enable rapid response to potential security incidents. EDR enhances an organization's capability to identify and mitigate threats before they escalate, improving overall cybersecurity posture. This proactive approach to endpoint protection is essential for defending against increasingly sophisticated cyber attacks in today's threat landscape.
