Airbnb Data Privacy and Security Engineering: Inspekt Data Classification Service and Angmar Secret Detection

Airbnb’s second privacy‑security article describes how the Inspekt service automatically classifies personal and sensitive data across diverse stores using regexes, Aho‑Corasick tries, machine‑learning models and custom validators, measures validator quality, and how the Angmar system scans code repositories for secrets via CI checks and pre‑commit hooks, with plans to broaden coverage to more APIs and data stores.
