Stellar Cyber

AI-driven security operations platform combining SIEM, NDR, and automated response for lean teams.

Stellar Cyber packages the security operations stack, including data collection, SIEM, network detection, and automated response, into one platform priced and designed for MSSPs and smaller enterprise teams. Its Open XDR approach ingests from existing tools rather than requiring rip-and-replace. Founded in 2017, it emphasizes outcomes achievable without a large SOC staff.
