Cylake develops a cybersecurity platform designed to analyze and protect enterprise infrastructure using an integrated data architecture. The platform combines hardware and software components that collect and process operational and security data from networks, endpoints, cloud workloads, and other technology systems. Its system uses artificial intelligence models and automated workflows to analyze activity, identify abnormal behavior, and generate alerts for investigation and response. Cylake’s platform is designed to operate within on-premises or private cloud environments so organizations can process and store security data within their own infrastructure. The technology consolidates multiple security functions into a unified system that provides visibility across an organization’s technology stack and supports monitoring, analysis, and incident response activities.
