View source for Definition:Endpoint detection and response (EDR)

🛡️ '''Endpoint detection and response (EDR)''' is a category of cybersecurity technology that continuously monitors and analyzes activity on individual devices — laptops, servers, mobile phones, and other network endpoints — to detect, investigate, and contain threats in real time. In the insurance context, EDR has become a critical factor in [[Definition:Cyber insurance | cyber insurance]] [[Definition:Underwriting | underwriting]], with many carriers now requiring policyholders to have EDR solutions deployed across their environments as a precondition for coverage. The presence or absence of EDR can directly affect [[Definition:Premium | premium]] pricing, available coverage limits, and even whether a [[Definition:Risk | risk]] is bindable at all.

⚙️ EDR platforms work by installing lightweight software agents on each endpoint, which collect telemetry data — process executions, file modifications, network connections, registry changes — and transmit it to a centralized analysis engine. This engine applies behavioral analytics, machine learning, and threat intelligence feeds to identify anomalous patterns that signature-based [[Definition:Antivirus software | antivirus]] tools might miss, such as fileless malware or lateral movement by an attacker who has already breached the perimeter. When a threat is detected, EDR can automatically isolate the compromised endpoint, terminate malicious processes, and generate a forensic timeline that proves invaluable during [[Definition:Cyber incident response | incident response]] and subsequent [[Definition:Claims management | claims]] investigations. For insurers and their appointed [[Definition:PCI forensic investigator | forensic investigators]], the logs and telemetry preserved by EDR tools often determine whether a [[Definition:Data breach | breach]] was contained quickly or escalated into a systemic event.

📈 From a [[Definition:Risk management | risk management]] perspective, EDR adoption has reshaped the cyber insurance market's approach to loss prevention. Carriers and [[Definition:Managing general agent (MGA) | MGAs]] specializing in cyber lines increasingly treat EDR not merely as a checkbox but as a measurable indicator of an organization's security maturity — comparable to how fire suppression systems influence [[Definition:Property insurance | property insurance]] terms. Insureds that deploy EDR with 24/7 managed detection and response (MDR) services tend to experience shorter dwell times and lower average claim costs, which feeds back into more favorable [[Definition:Loss ratio (L/R) | loss ratios]] for portfolios that enforce EDR requirements. As ransomware and supply-chain attacks continue to drive [[Definition:Cyber insurance | cyber]] losses globally, EDR has evolved from a technical nicety into a foundational element of insurable cyber hygiene.
