Case Study: Houwzer achieves API-level security and automated threat blocking with Traceable AI

Reinventing how people buy and sell homes—securely online

Houwzer, a modern real estate and mortgage brokerage, needed to secure a highly complex, monolithic API that powers personalized and localized home‑buying and selling workflows. The company lacked visibility into how the API was used and where sensitive data flowed, creating the risk of unauthorized access to PII. To address this, Houwzer turned to Traceable AI to protect and observe its API layer.

Traceable AI provided API‑level observability and ML‑driven, real‑time threat detection and blocking, surfacing inappropriate information flows between user roles and delivering security insights directly to developers. As a result, Traceable AI helped Houwzer uncover and fix three previously undetected vulnerabilities, automatically block hundreds of threats per day, prevent private‑data leaks, avoid hiring a dedicated security team, and securely support 1,300+ digital real‑estate transactions per year as the company scales.
