ETALON is a privacy auditing platform built for developers and AI-powered coding agents who need to detect data privacy risks within applications. Delivered as a Rust-based command-line tool, it performs deep analysis of source code, configuration files, and live websites. The system uses six parallel scanners to inspect code imports, database schemas, server behavior, DNS records, and tracking technologies. It identifies privacy concerns such as unauthorized trackers, cookie misconfigurations, and server-side analytics that bypass consent mechanisms. ETALON’s domain registry tracks more than 111,000 known tracking domains and vendor services, enabling accurate identification of third-party data flows. Every detected issue is enriched with GDPR references, severity scores, and contextual insights to help developers understand compliance implications. The platform can also automatically generate GDPR-ready privacy policies by analyzing the technologies and data processing patterns present in the codebase. A built-in website scanner runs through headless Chromium to detect frameworks, intercept network requests, and verify consent banner behavior. ETALON integrates with AI development tools through the Model Context Protocol, allowing AI assistants to audit pull requests and suggest privacy fixes. By combining static analysis, live scanning, and AI integration, ETALON provides a comprehensive solution for privacy engineering.
