View company profile

Through groundbreaking technology, Stellar Cyber is revolutionizing cybersecurity at Stellar Cyber, Inc. by empowering organizations to illuminate the darkest corners of their security operations. The company's core mission is to enable businesses to see incoming attacks, understand how to combat them, and act decisively to protect what matters most. Stellar Cyber's innovative Open XDR (Extended Detection and Response) platform is at the forefront of this revolution, offering a comprehensive, unified, and AI-powered solution designed to simplify complexity and empower lean security teams of any skill level. This platform uniquely integrates Next-Generation SIEM (NG-SIEM), Network Detection and Response (NDR), and Multi-Layer AI™ into a single license, providing unparalleled visibility and control.

Stellar Cyber's approach addresses critical challenges faced by modern security operations centers (SOCs), such as tool fatigue from managing multiple, siloed security products and the overwhelming volume of alerts. By ingesting data from virtually any source across the entire security stack – including EDR, email, firewall, cloud logs, identity providers, and OT environments – the platform normalizes and enriches this data, providing a consistent format for context-aware analysis. The Multi-Layer AI™ engine then automatically analyzes this unified data to detect and correlate alerts into actionable incidents, significantly reducing alert fatigue and improving threat detection accuracy. This automation extends to response, with capabilities embedded directly into the analyst's workflow, eliminating the need for separate SOAR tools and streamlining the entire incident lifecycle from detection to remediation. The platform's API-first architecture ensures seamless integration with existing security tools and workflows, including ticketing systems and collaboration platforms, allowing organizations to retain their current investments while enhancing their overall security posture. Stellar Cyber is committed to an open ecosystem, as demonstrated by its Open Cybersecurity Alliance Program, which fosters integration with a wide array of best-in-class cybersecurity solutions. This focus on openness and automation translates into tangible benefits for customers, including a reported 20X improvement in Mean Time to Detect (MTTD) and an 8X improvement in Mean Time to Remediate (MTTR).
