Case Study: Finder secures 300,000 users' financial data with Auth0

How Finder Protects 300,000 Users’ Financial Data With Auth0

Finder is a global comparison site (2.6 million monthly visitors) that launched an app connecting users’ bank accounts to track spending and recommend savings. To protect sensitive financial and membership data for roughly 300,000 users, Finder needed a robust identity strategy to consolidate multiple user systems, reduce the attack surface, and defend against brute‑force and breached‑password attacks.

Finder implemented Auth0 as its IAM provider, migrating hundreds of thousands of accounts into a single, secure system and enabling anomaly detection, brute‑force protection, and continuous token reauthentication. The solution blocked malicious login attempts, strengthened data security, sped up product development by outsourcing identity, and created a secure foundation for international rollout and future innovation.
