Stellar Cyber

Stellar Cyber offers an Open XDR platform designed to simplify your security operations by consolidating data from all your existing tools. Instead of jumping between disconnected consoles, you can view your entire attack surface—including cloud, network, and endpoints—within a single unified interface. The platform uses machine learning to correlate alerts and identify complex threats that individual tools might miss on their own.

You can automate your incident response workflows to stop attacks in real-time and reduce the manual workload on your security team. It is built for mid-market enterprises and Managed Security Service Providers (MSSPs) who need enterprise-grade protection without the complexity of managing dozens of standalone products. By integrating with your current tech stack, it helps you maximize your existing investments while significantly cutting down your mean time to detect and respond to breaches.
