Case Study: Wise achieves faster threat mitigation and reduced risk with Bugcrowd Bug Bounty

Platform-powered Bug Bounty Helps Transferwise Innovate Payment Security

TransferWise, a global technology company that moves money worldwide, found that traditional compliance-oriented penetration tests didn’t provide the depth or real-world coverage needed to protect its payment systems. Seeking more than a checkbox audit, the security team wanted a testing model that exposed more realistic threats across their applications.

TransferWise launched a Bugcrowd bug bounty—starting private and later going public—which delivered continuous, crowdsourced testing and rapid findings (including a P1 business‑critical vulnerability within 24 hours). The program reduced risk, sped threat mitigation, standardized vulnerability handling, and scaled into an efficient workflow, helping strengthen application security and foster a security-first culture.
