Behavioral detection and incident-response solutions for endpoints and, in the case of XDR, across all infrastructure layers.
An EDR (Endpoint Detection and Response) is a security agent deployed on each endpoint (workstation, server) that continuously collects system events, analyzes behavior in real time and can automatically isolate or remediate detected threats, independently of classical antivirus signatures. It records detailed telemetry (launched processes, network connections, file modifications, registry keys) that is valuable for post-incident investigations. XDR (Extended Detection and Response) extends the EDR logic to all of the infrastructure's telemetry sources: network, email, cloud, identities, enabling broader correlation and more accurate detection of complex attack chains. These solutions have become a major cyber underwriting criterion as their deployment is correlated with significantly shorter detection and containment times. Some insurers contractually require an EDR to cover high limits, or grant premium reductions for its presence. The CrowdStrike incident of July 2024, however, illustrated that the EDR itself can become a vector of systemic risk when a single agent is deployed on millions of machines.
A cyber insurer analyzes its portfolio and finds that the average loss ratio for insureds with a certified EDR is 35 percent lower than for those without. It integrates this criterion into its underwriting questionnaire with a premium reduction grid of up to 12 percent.
