Stellar Cyber MSSP Providers

Stellar Cyber is an Open XDR platform that provides security operations capabilities by correlating data from multiple security tools and data sources. The platform uses AI-driven analytics to detect threats, automate investigation, and orchestrate response across network, endpoint, cloud, and application environments without requiring vendor lock-in to a single security ecosystem.

MSSPs use Stellar Cyber as a vendor-agnostic security operations platform that integrates with existing client security tools rather than replacing them. The Open XDR approach allows providers to deliver managed detection and response services across diverse technology environments.

How to Evaluate an MSSP for Stellar Cyber

  • Ask about the provider's integration depth with your existing security stack, since Stellar Cyber's value depends on how many data sources it correlates.
  • Evaluate whether the MSSP configures Stellar Cyber's AI-driven correlation to reduce noise specific to your environment rather than running default analytics.
  • Understand how the provider handles response orchestration across the multiple security tools that feed into the Open XDR platform.
