About Realm.Security
Realm.Security sells a security data pipeline that sits between telemetry sources and destinations such as SIEM, data lake and AI SOC. It reduces the volume of data sent to the SIEM, which lowers ingest costs, while keeping a full searchable copy in Data Haven. The company says customers typically cut SIEM costs by 40% or more and reduce data volume by 50 to 70% without losing detections. It sells to security operations teams, including those at a benefits and payroll provider and a global manufacturer. The platform uses Realm Clarity AI to read sources and destinations, recommend what to keep, cut, enrich, redact and route, and show the reasoning. Rules run in a pending state against live data before the customer approves them. Detection Integrity then checks that every reduction still lets detections fire, on the customer's own data. The company also offers a 7-Day Data Assessment, where it proves reduction, detection integrity and ROI on one chosen source.
