Stellar Cyber is a cybersecurity technology company that builds an AI-native Open XDR SecOps platform designed to unify security tools, automate threat detection and response, and empower lean security teams in enterprises and Managed Security Service Providers (MSSPs).[1][2][8] The platform solves the problem of fragmented security stacks by providing comprehensive visibility across cloud, on-premises, OT environments, endpoints, networks, and SaaS apps through features like AI-driven SIEM, NDR, UEBA, ITDR, Multi-Layer AI™, and automated hunting—serving mid-sized organizations and MSSPs with over 14,000 customers in 50+ countries.[2][3][4][8] Its growth momentum is evident in adoption by one-third of the top 250 MSSPs, patented innovations like Kill Chain Loop™, and recognition as a leader in award-winning AI-powered security operations.[3][4]
Stellar Cyber was founded in 2015 by Aimei Wei, who aimed to democratize cybersecurity by leveraging AI and machine learning to address the dilemma of complex, inefficient security tools.[3] Wei invented a family of cybersecurity sensors that index security metadata at ingestion for easy normalization and correlation, enabling AI to spot anomalies across the attack surface including cloud, SaaS, apps, users, endpoints, and networks.[3] Early traction came from integrating with popular security tools and delivering visibility into hidden threats, evolving into the leading Open XDR provider for enterprises and MSSPs through relentless R&D.[3]
Stellar Cyber rides the trend toward AI-native, unified SecOps platforms amid exploding cyber threats, cloud migrations, and OT vulnerabilities, where traditional point solutions create blind spots and alert fatigue.[1][2][3][8] Timing is ideal as organizations demand Open XDR to consolidate tools—Stellar Cyber influences the ecosystem by enabling autonomous SOCs, supporting MSSPs in scaling services, and integrating seamlessly with EDR, IAM, email, and cloud security, thus reducing costs and risks across the kill chain.[2][4][6] Market forces like regulatory pressures and skilled analyst shortages favor its human-augmented automation, positioning it as a trusted leader shaping proactive cybersecurity.[3][4][7]
Stellar Cyber is poised to expand its dominance in AI-driven SecOps, with next steps focusing on enhancing Multi-Layer AI™, cloud/OT integrations, and autonomous response to counter evolving threats like AI-powered attacks.[1][3][8] Trends such as zero-trust architectures, generative AI in security, and MSSP growth will propel it, potentially growing its 14,000+ customer base through global expansion and partnerships.[2][4] Its influence may evolve by setting standards for open platforms, helping lean teams "see what’s coming and act fast," reinforcing its mission from a scrappy sensor innovator to cybersecurity illuminator.[2][3]
Stellar Cyber has raised $65.1M across 4 funding rounds. Most recently, it raised $38.0M Series B in November 2021.
