Halon operates a security-focused email platform built on C++, Linux, and Postfix, with an active ML engineering track (MLflow, end-to-end threat forecasting pipelines, automated MLops). The hiring mix—3 engineers, 2 security roles, and 3 marketing—reflects a company shifting from pure infrastructure toward threat-detection automation and category positioning. Internal pain points center on manual processes and transitioning MLops to production, consistent with project work on ML model deployment and threat forecasting at scale.
