Stellar Cyber is a security analytics provider MoreLess
Stellar Cyber operates in the cybersecurity market, offering an advanced security platform designed to enhance the efficiency and effectiveness of security operations. The company serves a diverse range of clients including enterprises, managed security service providers (MSSPs), and public sector organizations. Stellar Cyber's core product is its Open XDR (Extended Detection and Response) platform, which integrates with existing security tools to provide a unified view of security data. This platform helps in reducing Mean Time to Identify (MTTI) and Mean Time to Respond (MTTR) to threats by at least 8x and 20x respectively, thereby improving the overall security posture of its clients. The business model is primarily subscription-based, generating revenue through licensing fees for its software solutions. Stellar Cyber also offers additional services such as threat hunting and security consulting, further diversifying its revenue streams. The company's platform is built on a scalable data lake architecture, enabling pervasive data collection and transformation across all tools. This ensures comprehensive visibility and faster investigation and response to security incidents. By automating detection and response, Stellar Cyber helps organizations reduce risk without disrupting their operations.
