About
Realm.Security is an AI-native security data pipeline platform that gives security teams complete control over what gets collected, filtered, and routed—without needing a dedicated engineering team. Built by veterans of Boston-area cybersecurity firms Rapid7 and Carbon Black, Realm offers modular products including Realm Focus (ML-powered log filtering to cut SIEM costs), Realm Unity (log normalization for faster detection), Realm Privacy Guard (sensitive data detection and masking), and Realm Data Haven (compliance-ready data archiving). The platform enables organizations to reduce log volume by 80%+ while preserving critical detection signals, achieving vendor-agnostic data normalization and eliminating pipeline complexity. Realm raised $15M in a Series A led by Jump Capital and has more than doubled its customer base, serving Fortune 500 enterprises and mid-market security teams looking to reduce SIEM spend.
