EDR Explained: Why Every Business Needs Endpoint Detection and Response

What EDR Does That Antivirus Cannot

Traditional antivirus focuses on preventing known malware from executing. Endpoint Detection and Response (EDR) goes further by continuously monitoring endpoint activity, detecting sophisticated attacks, and providing the tools to investigate and respond. Think of antivirus as a lock on your door and EDR as a security camera system with an alarm and remote response capability.

Continuous Visibility

EDR records detailed telemetry from every endpoint: process execution chains, file modifications, network connections, registry changes, and user activities. This data is indexed and searchable, enabling security teams to ask questions like "show me every process that connected to this IP address in the past 30 days" or "which endpoints have this file hash." This visibility is essential for threat hunting and incident investigation.

Automated Response

When EDR detects a threat, it can respond automatically without waiting for a human analyst. Response actions include isolating the endpoint from the network (while maintaining management connectivity), killing malicious processes, quarantining files, and collecting forensic data. Automated response reduces the time between detection and containment from hours to seconds, limiting the damage an attacker can cause.

Investigation and Forensics

After an incident, EDR provides the forensic data needed to understand what happened. Process trees show exactly how the attack progressed. Timeline views reconstruct the sequence of events. Network connection logs reveal data exfiltration attempts. True Protection's EDR capabilities give you complete attack visibility with the ability to pivot from a single alert to the full scope of an incident within minutes.
