Realm.Security

Featured

Realm.Security describes itself as a SOC-aware security data pipeline, scoped to security telemetry rather than spanning IT and observability. The vendor states it reduces, enriches, redacts and routes security telemetry, validates filtering against live detections before it is applied, and retains an immutable raw copy of everything by default. Vendor-stated: a customer cut FortiGate log volume by 83 percent with no detections lost, and deployment takes 7 to 10 days without professional services.
