Matthew Horrocks developed and enhanced security observability features for the elastic/endpoint-package repository over four months, focusing on Windows telemetry, firewall anti-tamper controls, and kernel process event metrics. He implemented new schema definitions and data modeling in TypeScript and YAML, expanding metrics coverage for Windows HTTP interactions and kernel-level events. His work included documentation-driven development, configuration management, and policy observability, enabling more accurate monitoring and faster incident response. By updating internal state management and integrating advanced policy settings, Matthew improved the reliability and flexibility of endpoint security, delivering deeper diagnostics and supporting data-driven optimization without introducing major bugs during this period.
In January 2026, shipped Kernel Process Events Metrics and Observability Enhancements for elastic/endpoint-package, strengthening kernel-level observability and data stream metrics. Implemented new kernel_process_events fields and updated internal state management documentation, enabling stronger monitoring and faster issue resolution.
