Stellar Cyber, founded in 2015 by cybersecurity veteran Aimei Wei, develops an Open XDR platform that consolidates fragmented security tools into a unified security operations environment. The platform integrates AI-driven SIEM, Network Detection and Response (NDR), and a Multi-Layer AI engine to automate threat detection and response across identity, network, cloud, and endpoint domains.
The company's core product addresses a common operational problem: security teams managing thousands of daily alerts from disconnected tools. By unifying these inputs into a single platform, Stellar Cyber aims to reduce the time it takes to detect, contextualise, and respond to threats - from days to minutes, according to the company. The Multi-Layer AI approach combines machine learning, graph ML, generative AI, and hyper-automation to augment human analysts rather than replace them.
Stellar Cyber's platform is positioned primarily for two audiences:
- Mid-market enterprises that need enterprise-grade security capabilities without the resources to staff and maintain sprawling security stacks
- Managed Security Service Providers (MSSPs) that deliver security operations to multiple clients
The company describes itself as a pioneer of the Open XDR category - a security architecture designed to integrate with existing tools rather than requiring organisations to replace them. Technical work at Stellar Cyber spans AI and machine learning research, platform engineering, and security data infrastructure.
