Our verdict on OpenEDR

OpenEDR is an open-source endpoint detection and response platform for organizations and security professionals investigating activity on Windows endpoints. Its agent collects process, file, registry, and network telemetry for analysis, with local event storage, suspicious-activity alerts, MITRE ATT&CK visibility, event search, and root-cause investigation views. It is a fit for teams that want to operate an EDR platform themselves and can manage that deployment; it is not a match for teams requiring verified support for endpoint operating systems beyond Windows.

Deployment choice shapes the cost and operating model. The project supports self-hosting, which has no Xcitium fees, and an optional Xcitium-hosted platform. According to the product notes, the hosted option charges for event storage and limits storage to three days. OpenEDR is described as free, but organizations weighing the hosted path should account for that storage charge and retention limit; self-hosting avoids Xcitium fees while leaving platform operation to the organization. No paid plan tiers are described.

The investigation workflow is the product's main draw: collected telemetry can be searched, mapped to MITRE ATT&CK, and examined through process hierarchy and file or device trajectory views. Elasticsearch and Filebeat are named integration options for telemetry streaming, which suits teams already working with that stack. Community support and documentation are the listed support channels. Choose OpenEDR if free, open-source Windows EDR visibility and investigation are the priority and self-hosting is practical. Consider another option if broader endpoint OS coverage or specified automated response is required; neither is established for this product.
