Which security solution combines prevention, detection, and response to threats?

• A. Endpoint Detection and Response (EDR)
• B. Endpoint Protection Platform (EPP)
• C. Signature File Detection
• D. Continuous Real-Time Monitoring

Answer: (A)

Think of a security system that not only blocks threats but also watches for suspicious activity and takes action to stop and fix problems once they’re found. Endpoint Detection and Response provides this combination: it continuously monitors endpoints, uses analytics to detect anomalies or malicious behavior, and offers automated or guided response options to contain, kill, or remediate threats and to collect details for investigation. This integration of prevention (through proactive controls), detection (through monitoring and analytics), and response (through containment and remediation actions) embodies a complete threat-focused approach, not just a single capability.

The other options don’t deliver the full trio. An Endpoint Protection Platform emphasizes preventive controls and may include some detection, but it’s generally more focused on stopping threats upfront than on post-compromise detection and fast response. Signature File Detection relies on known signatures to catch threats, which misses unknown or polymorphic malware and typically lacks robust response workflows. Continuous Real-Time Monitoring describes ongoing visibility, which is valuable but is a capability rather than a full security solution that actively prevents, detects, and responds.
