Modern security operations teams are drowning in alerts - facing thousands of daily notifications from fragmented tools while sophisticated attacks slip through the cracks. Stellar Cyber exists to end this chaos with an Open XDR platform that unifies security operations, transforming overwhelmed teams into efficient threat hunters who stop attacks in minutes, not days.
Founded in 2015 by cybersecurity veteran Aimei Wei, Stellar Cyber pioneered the Open XDR category to solve the fundamental problem of tool sprawl. By integrating AI-driven SIEM, Network Detection and Response (NDR), and Multi-Layer AI into a single platform, Stellar Cyber empowers lean security teams at mid-sized organizations and MSSPs to see incoming attacks, understand their context, and respond automatically. The platform's human-augmented autonomous SOC approach combines machine learning, graph ML, generative AI, and hyper-automation to detect threats across identity, network, cloud, and endpoint environments - delivering enterprise-grade security without requiring enterprise-scale resources.
