Stellar Cyber

Stellar Cyber is an AI-native security operations platform founded in 2015 by Aimei Wei, a former Cisco and Nortel engineer, on a mission to democratize and transform security operations through artificial intelligence. The company's Open XDR platform unifies detection, investigation, triage, and automated response across the entire attack surface — covering cloud, SaaS, applications, users, endpoints, and network environments — into a single consolidated solution. By correlating telemetry from hundreds of integrated security tools into AI-driven cases and workflows, Stellar Cyber dramatically reduces the alert noise and manual correlation burden that overwhelms analysts at mid-market enterprises and MSSPs. The platform is purpose-built for lean security teams and Managed Security Service Providers (MSSPs) who need enterprise-grade protection without the cost and complexity of legacy SIEM and point-product stacks. Stellar Cyber has earned recognition from Gartner Peer Insights and industry analysts for its cost-effectiveness and comprehensive attack surface coverage, and serves customers across five continents with approximately 147 employees as of 2026.
