CrowdStrike's Threat Graph is a sophisticated security analytics tool designed to manage and analyze massive amounts of data with remarkable speed and flexibility. It processes hundreds of billions of security events daily by employing an innovative "append-only" data collection approach, which reduces latency and increases throughput. The simplicity of its design, using a single table to represent both vertices and edges, allows it to scale effectively while maintaining system performance. CrowdStrike emphasizes the importance of a tight feedback loop to monitor changes and ensure system reliability, supported by extensive metrics collection and visualization tools. This approach not only addresses the need for processing large data volumes but also allows Threat Graph to adapt to evolving market demands, securing the cybersecurity of millions of customers worldwide.
