During December 2025, Nixhub contributed to the SeleniumHQ/docker-selenium repository by developing a security-focused feature for the Selenium Grid Helm chart. They implemented network policy injection using YAML and Helm, enabling opt-in pod network isolation for Grid nodes deployed in Kubernetes environments. This enhancement addressed the need for stronger security in multi-tenant and CI/CD scenarios, aligning with Kubernetes best practices while minimizing disruption to existing deployment workflows. Nixhub ensured the integration was well-documented and maintained compatibility with current Helm processes, demonstrating a focused approach to DevOps and infrastructure security within the scope of a targeted, single-feature contribution.
