Stellar Cyber is an AI/ML-driven Open XDR platform that unifies NDR, SIEM, SOAR and TIP into a single platform — automatically correlating events and accelerating the entire SecOps lifecycle from detection to response.
Stellar Cyber is an AI/ML-based Open XDR platform that consolidates NDR (Network Detection), SIEM (log analytics), SOAR (automated response), TIP (threat intelligence) and UEBA (user/entity behavior analytics) in a single platform. It ingests logs from any vendor's firewall, EDR or cloud service, then uses AI to correlate fragmented events and stitch them into a single "attack story" (Incident) for the analyst.
Modern cyber attacks unfold over weeks and months in multiple stages, scattered across many security products' logs. Manually stitching these together is too slow, and security teams are chronically understaffed. Stellar Cyber lets AI do the correlation 24×7, rebuilding attack chains automatically so analysts can focus on prioritized incidents and SOAR can trigger automated block, isolate and notify workflows.
