To which of the following security categories does an EDR solution belong?

An EDR (Endpoint Detection and Response) solution is a technical security control. Technical controls use technology to protect systems and data, such as firewalls, intrusion detection systems, encryption, and antivirus software. EDR specifically uses software agents on endpoints to monitor for malicious activity, detect threats, and respond to incidents, directly implementing security through technological means. Physical controls relate to tangible barriers and environmental security (e.g., locks, fences, cameras). Operational controls involve processes and procedures (e.g., incident response plans, security awareness training). Managerial controls are about governance and risk management (e.g., policies, regulations, audits). EDR does not fit into these categories as its primary function is technology-based threat detection and response.
