Stream.Security is a Cloud Detection and Response (CDR) platform built for security operations teams. It uses a proprietary real-time CloudTwin™ technology to maintain a live, stateful model of an organization's cloud environment, enabling context-aware threat detection and investigation across cloud, Kubernetes, identity providers (IdP), and SaaS platforms. The platform addresses gaps in traditional SIEM-based approaches by enriching raw log data with contextual cloud state information, making it suitable for AI-driven analysis and autonomous triage. It provides full MITRE ATT&CK coverage out of the box, supports custom rule creation via AI, and delivers correlated attack storylines that combine posture, network, identity, and runtime activity — without requiring manual queries. Stream.Security supports multi-cloud environments including AWS, Azure, and GCP, as well as SaaS platforms and Kubernetes. It offers stateful User and Entity Behavior Analytics (UEBA), dynamic detection traps, and the ability to integrate existing endpoint and runtime signals into a unified threat picture. The platform is positioned to reduce SIEM cloud log processing costs, and can displace point tools such as AWS GuardDuty and AWS Config. It targets SecOps teams ranging from startups to large enterprises.
