Stream.Security is a cloud security company that provides a cloud detection and response platform aimed at security operations (SecOps) teams. The company's core technology is called the "CloudTwin" model, which creates a real-time digital twin of an organization's cloud infrastructure to enable threat detection, exposure modeling, and accelerated incident response. The platform is designed for dynamic cloud enterprise environments and offers SecOps teams visibility into their cloud infrastructure by modeling the past, present, and future states of their environment. This approach allows analysts to identify exposures and threats, determine attack paths, and assess blast radius across cloud infrastructure elements. Key capabilities of the Stream.Security platform include AI-assisted investigation workflows, real-time cloud threat and exposure modeling, attack path analysis, and tools aimed at reducing mean time to response (MTTR). The platform also targets operational challenges within SOC teams, such as alert fatigue and analyst burnout, by streamlining investigation processes and reducing knowledge gaps. The company was previously known as Lightlytics, originally focused on helping DevOps teams predict and prevent cloud infrastructure failures before deployment. It has since repositioned as a cloud detection and response vendor targeting security operations use cases. Stream.Security is backed by investors including Citi Ventures, USVP, Energy Impact Partners, Cervin Ventures, Glilot Capital, and TLV Partners.
